The Editor’s Perspective
The year started with a plethora of trade shows starting of with the World of Concrete, the Asphalt Show and the Rental show early in the year - all in the USA. Then followed SAMOTER in Italy which was the precursor for the big one - ConExpo/ConAgg which took place in Las Vegas. Following this was the Spanish show SMOPYC. For editors, exhibitors and visitors it has been a busy start to the year. Fortunately, although there has been a lot of new plant and equipment introduced, the global state of the construction industry (with a few exceptions) means that although there is a great deal of interest in what is new, the finance is not available to take advantage of the higher productivity offered by most. For me, it also means that I can take time to review the new equipment and not rush to hit the headlines without due consideration to the facts. (For instance the Cat TH514 on show at ConExpo was not, as some international magazines have said, ‘new’ - it has been available in Europe for over 2 years. Those that have come to read Contractors World over the past 20 months - yes it is almost 2 years already - will have recognised that we prefer to give a more detailed review than most other magazines - for instance, there are 6 pages of editorial in this issue on the Caterpillar stands alone but, given the amount of new equipment being unveiled I believe it is justified. Atlas Copco, Wirtgen, Bomag and others are also covered in depth according to the new equipment introduced. To our 13,000 plus regular readers each month (increasing all the time), there will be other ‘At The Shows’ supplements covering leading brands such as Komatsu, Doosan, Volvo and others, as well as some of the smaller, lesser known brand names with interesting products. I am often asked ‘How do I select the order of companies to feature?” There is no magic formula and circumstances often dictate timing. In many instances, the equipment display has been so new that very little information was available, so we prefer to wait until we can get sighting of the specifications and other information that is important to our reader. However, more often than not, it is the order in which the slowly reducing pile of press releases is stacked. We have no favourites and editorial cannot be bought. If any reader would like me to review specific information on a company’s products then please let me know and we will see what can be done, but, of course, it also has to be of interest to of our worldwide readers. The big challenge now is to get reports on how the new machines are actually performing and that can be difficult. Manufacturers are only too pleased to tell you how productive the new models are but are slow to actually send in field reports from customers to support their sometimes incredible claims. You would not believe the number of superlatives and spurious claims that are made which we have to delete, but that is the job of an Editor. Many thanks to our increasing global readers and the positive comments emailed in as each issue is distributed. We are pioneering a new style of digital publishing and appreciate feedback to further enhance our offering. We are trying to keep up with developing technology and our magazines should be available FREE, and without any need to register, on any digital display. If you have problems with any specific type of reader, please let me know so I can get the technical people to solve the problem.

Wirtgen Latest milling machine offers more versatility
The Wirtgen Group never fails to show the world why the group is a world leader in road paving and mine milling industries, and the company delivered at ConExpo 2011 with a large stand on which the various group companies where represented - Wirtgen, Kleemann, Vögele and Hamm. Under the ‘Wirtgen’ brand, was the latest model in the range of twin-engine cold milling machines. The largest in the range, the W 250 is designed for high productivity, being able to remove up to 1,200 t of asphalt per hour. The operator can chose to use both engines giving a combined maximum output of 730 kW (980 hp). Alternatively, one engine can be turnoff to save fuel for applications where an engine rated at 380 kW (510 hp) is still significant. As Wirtgen management explained to Contractors World, the variety of applications in many countries, especially North America, requires a machine that is easily adapted to suit different requirements - even on the same job. With six different milling widths ranging from 2.2 m (7.2 feet) to over 4.4 m (14.4 ft) at depths up to 350 mm, it can work single carriageways or dual-lanes and airport runways at high speed. A choice of three milling drum speeds facilitates matching material to productivity The W 250 is also equipped with WIDRIVE,which is Wirtgen’s intelligent machine management system, which not only eases the workload of the operator, but also guarantees fuel efficient and environmentally compatible milling. WIDRIVE: Intelligent Machine Management The Widrive automatically manages a range of functions which the operator would normally have to do. It balances various function for optimum performance - engines, travel speed, milling drum drive and conveyor belt, water spray systems as well as the automatic PTS system (a device to ensure that the machine is always parallel to the road surface) and Level pro levelling system. In order to optimize fuel consumption, milling output and the overall efficiency can be managed by using a selector switch. This means that the ideal milling output can be achieved even under unpredictable milling conditions, by directly switching to the optimal speeds during the milling process. The operating platform provides the operator with an optimal work environment to aid productivity. A key component is a multifunctional control display which can be swung to the left or right of the operator
Wirtgen SP15 Slipform Paver

– together with the Level Pro control panel. The total unit is designed to show operating status and servicing data in an easily comprehensible way. The W 250 joins the W 210, the first dual engine model and the W 200, a single engine model. Latest slipform pavers introduced to the North American market Launched in Europe last September, ConExpo was the first opportunity for the wider North American market to see close up the latest models in the Wirtgen range of slipform pavers - the SP 15 and SP 25 concrete slipform pavers. Until now, Wirtgen has not heavily marketed these product in the USA and Canada, even though they have been producing such machines for over 50 years. Although the SP 15 and SP 25 are the first two models to be made available through the company’s dealer network, the other models in the line - SP 500, SP 850, SP 1500 and SP 1600 – will be gradually introduced. Wirtgen chose these two models as presenting the widest applications as they are multipurpose machines able to lay curbs and gutters, barriers, sidewalks, V-ditches, slabs, and special applications. Both machines can be quickly configured on-site for left- or right-side pouring. The SP 15 has a maximum paving width of 1.88 m (6 ft) maximum barrier/parapet placement height of 1.3 m (4 ft 3 in), and weighs 12,747 kg (27,500 lb). The SP 25 has a maximum paving width of 3.65 m (12 ft), and maximum barrier/parapet placement height of 1.88 m (6 ft) Its maximum weight is 18,000 kg (39,600 lb). GPS technology aids productivity Wirtgen is also promoting the latest in automatic profiling using advanced GPS and laser technology. When specified with the SP15 and SP25, the technology allows for accurate profiling of curves and other dimensions with little operator involvement. It eliminates the need for string lines and additional workers. This advanced solution speeds up the process, is more accurate and more efficient.

Allu New Stabilisation Mixer The Finnish manufacturer of various types of screening buckets and other excavator attachments used ConExpo to officially launch the new ALLU PMX Power Mixer. The new mixer is a part of the ALLU Mass Stabilisation System primarily designed for stabilising soft soils or contaminated soils and processing dredged sludge but is also suitable for other purposes. The new PMX mixer has many new innovations such as Allu soil stabilizer in action inclined drums that minimize the “dead area” of the bottom frame. This ensures easy penetration through hard crust soil layers. Designed as a hydraulic mixing tool for excavators, the drums rotate simultaneously in three ways at the same time mixing the material in a controlled way. Inclined drums and streamlined frame design ensure easy penetration through hard crust layers. ALLU PMX can process different materials up to a depth of 7 m (using the option 2 m extension tube), depending on the chosen model, the excavator’s reach and the quality of the material. The binder is fed by compressed air into the ground through a tube to the selected location near the drums. Hydraulic final drives get power from the excavator’s hydraulic system. The final drives rotate the mixing drums directly. The PMX is equipped with automatic torque adjustment on the hydraulic motor, gear box temperature indicator and drum rotating speed indicator to ensure effective jobsite control. The mixer is mounted as an accessory onto a standard excavator by a pin mounting or quick hitch adapter plate. Crusher-screening buckets Allu also demonstrated the D-Series crusher-screening buckets for excavators and wheel loaders. Available in 3 distinct series for light, medium and heavy-duty application. There is a screening bucket to suit excavators from 10 tonne and upwards and for wheel loaders from 4 tonnes. The buckets can screen and crush materials in different fragment sizes from 40 mm to 100 mm The heavy-duty buckets use two hydraulic motors; the others use only one. It is a standard fitting plate for use on excavators and wheel loaders. 2011 is also a milestone for the company as it celebrate 25 years since founded in 1986.

Atlas Copco Plenty to shout about as order books swell The Swedish company, Atlas Copco, certainly maximized on the opportunity that ConExpo 2011 and other shows presented to unveil new products from almost every division supplying the construction and related industries. This is not surprising given the strength of the company and its positive financial figures during a difficult global economic downturn. Atlas Copco’s first-quarter 2011 results show very strong growth in all business areas, both in terms of orders received and operating profit. The development was good in nearly all geographical regions and Atlas Copco expects demand to grow somewhat in the near term. “We have achieved a great result, thanks to the good global demand situation, our improved market presence in China and India, investments in products and services, and the hard work of our employees to strengthen the support for our customers,” says Ronnie Leten, President and CEO of the Atlas Copco Group. Revenues increased 27% organically while orders received grew 33% organically to US$3.6, a new record. Operating profit increased 52%, corresponding to a record margin of 21.9% . The margin was positively affected by efficiency improvements, Ronnie Lete, growing volumes and price increases, while changes in currency exchange rates had a Atlas Copco negative impact of about one percentage point. President and Chief Executive Officer “We faced big challenges in the quarter with the turmoil in northern Africa and the Middle East, and the tragic events in Japan,” Ronnie Leten says. “We’re glad that our businesses are adapting well and that all of our employees are safe.” The group has also announced a change to its business area structure. As of July 1, the Group will have four business areas instead of three, including a dedicated business area for construction equipment and related services. “With a stronger operational focus on specific customer segments and a steady stream of innovations, we have an excellent opportunity to grow our share of the market,” Ronnie Leten says. Mobile Crushers ConExpo and Samoter was the first opportunity for many to see what Atlas Copco is doing with the range of mobile crushers that is acquired as a result of taking over the German company, Hartl, in 2010. Atlas Copco’s new line of track-mounted mobile crushers and screeners are suitable for demolition, quarrying and road construction applications. The product range covers jaw crushers, impact crushers and cone crushers with a crushing capacity from 242 to 606 tons per hour and includes screeners with a capacity of 242 to 485 tons per hour. The four models of Powercrusher jaw crushers incorporate the unique “Quattro Movement.” Quattro Movement is made possible by an up-thrust toggle plate position. This causes a figure-eight motion in the moving jaw, which increases the feeding capacity and also produces a post-crush at the crusher outlet. There are six Powercrusher impact crusher models, all of which use optimized geometry in the crusher box with hydraulically adjustable swing beams. The result is a minimal percentage of oversized material, and high reduction ratios and throughputs.
Originally designed by Hartl and now part of the Atlas Copco group, and renamed the Powercrusher PC3, AT THE SHOWS
The PC 1000 cone crusher features cones that are compact units designed to accept an “all-in” infeed. This all-in feeding increases the particle-on-particle crushing, which in turn increases the quality of the end material shape, decreases wear and can eliminate the need for pre-screening. Bo-Göran Johansson, Vice President of Marketing for the Surface Drilling Equipment division, said, “The features of these products fit very well with the benefits we give our drill rig customers. The current generation of Powercrushers combines a straightforward design and user-friendliness with long-term reliable performance.” The complete Powercrusher line includes eleven different models of rock crushers and six screener models.
Latest in surface drill rigs ConExpo was the launch pad for Atlas Copco’s latest addition to the SmartROC range of surface drill rigs. The company boasts that SmartROC T40 for construction and aggregate production, is not only the most fuel efficient rig on the market but also the easiest one to use. The SmartROC T40 is a true 4- inch drill rig with air delivery of 335 cfm. The rig control system gives a wide hole range (76- 127 mm, 3”- 5”). Field tests show that decreasing the hole size by ½-inch reduces the fuel consumption by 15%. To contractors, flexibility is a major advantage, meaning that they can safely bid for road cut jobs in 3 inch applications as well as quarry work in 5 inch applications using the same rig. Add the optional radio-remote-control function soon to be available on this rig, and this will provide not only increased operator safety but also wider application coverage. The COP 2560 rock drill gives on average 10% higher impact energy efficiency than other rig types on the market. The unique driver design extends the driver life length of the rock drill. The completely new rig platform is the result of more than five years R&D work and feed back from field tests have confirmed that the operators really like the newly designed ergonomic user interface. The main operations are performed by just using two main joysticks and one screen. “For the first time it is as easy and comfortable managing a drill rig as an excavator. We listened to the customer feedback from existing rigs and made it so easy that even a non- driller, with a little training, can manage it,” says Hakan Aytekin, Product Manager, Atlas Copco Surface Drilling Equipment. Multiple savings The SmartROC T40 is Atlas Copco´s first drill rig with the new Tier 4 engine as required by legislation from 2011. The engine reduces the engine emissions from NOx by 50% and particulate matter by 90%, resulting in substantially less impact on the environment. Furthermore, ongoing field tests have shown that this rig lowers fuel consumption by up to 50%, depending on rock condition and, as a result, also reduces CO2-emissions. The design of the new SmartROC tries to reduce the number of areas which commonly cause problems. The amount of hoses has been reduced by 50%, couplings by 70% and hydraulic oil by 65%, reducing the risk of leakages and saving on maintenance. Depending on configuration, a SmartROC can help to improve factors such as drilling productivity, loadability and fragmentation. With Atlas Copco’s new version of the PC software ROC Manager, soon to be released, the documentation of the drill and blast operation is easily managed and analysed.

New Atlas Copco ROC FlexiROC T20 rock drill is highly manoeuvrable and ideal for construction site operations and other difficult access areas.
. . . also introducing the FlexiROC T20 R Atlas Copco has launched the FlexiROC T20 R compact radio-controlled, all-wheel drive surface drilling rig. This is for the construction industry requiring a low cost- per-meter drilled in the 1 ½ to 2 ½ inch (38 to 64 mm) range. The new rig is designed for such jobs as trench drilling and rock reinforcement applications. The T20 is matched to the Atlas Copco COP 1140, a new generation of hydraulic rock drill with double dampening. Self-drive to site through narrow city streets is one of the outstanding performance characteristics of the Atlas Copco The T20 is powered by a Tier III Cummins engine delivering FlexiROC T20 82 kW - enough power for use in numerous anchoring and bolting applications and for specialized drilling applications. For added versatility, options include a hydraulic rollover boom to increase coverage for bolting and specialized construction applications, and a hydraulic winch for securing the unit while tramming in extreme terrain. It is available with direct control or full radio remote control. The control panel on the rig controls tramming, drilling, and boom and winch functions, as well as any of the options. The panel can also be run from a cable extension as a backup to radio control.
New Power Pack The latest generation of hydraulic power packs from Atlas Copco provides a hydraulic power source for equipment requiring 5-10 gpm of hydraulic oil. The 118 kg Atlas Copco LP 18 horsepower power pack has an electric and recoil start system and features a thermostatically controlled oil cooler. This allows for faster warm-up times, which helps protect the hydraulic oil from overheating. A large front- mounted cooler and air fan cool both the hydraulic system and the engine in warmer climate conditions. The power pack features a new top cover to better protect the 18 HP B&S Vanguard petrol engine. The cover is opened easily for quick access to the hydraulic parts and air and oil filters to simplify maintenance. It is also equipped with flat-face, quick-release couplings that are placed on the front panel, along with the controls and hydraulic oil reservoir sight glass, for easy access. A strong frame, large air filled tires and foldable handles optimize their mobility. Fuel capacity is 7.2 litres and maximum pressure is 145 bar.

Page 11 Contractors World Vol 2 No 5 Show Supplement The Sandvik QI440 impact crusher for aggregate
At ConExpo, Sandvik Mining & Construction introduced some new products Crushing & Screening and used the occasion to launch some products into the North American from Sandvik market for the first time, although these had been pre-announced or shown in Europe at some time last year. Totally new was the QI440 - a purpose built tracked impact crusher designed to process aggregate and construction materials on site wherever, and whenever, they are required. Powered by a 330 kW C-13 Tier 3 compliant diesel engine, the Sandvik QI440 is carried on a manoeuvrable tracked undercarriage and incorporates a Sandvik CI322 impactor with a fluid clutch drive. Fed via a two-deck pre-screen, the crusher is a four hammer open-style rotor with a diameter of 1,150 mm and a width of 1,330 mm and discharges onto a secondary pan feeder. The plant is also equipped with a primary feeder and a separate two-deck pre-screen. The unit has an operating weight of 49.8 tonnes and is 15.5 m in length in transport configuration - this means that it is transportable in a single load, allowing it to be readily moved and redeployed for maximum utilisation. Optional equipment includes a remote diesel and water pump, an overband magnet for recycling and demolition applications, a dolly chassis for ease of transport and a recirculation conveyor The machine is designed to deliver throughputs from 300 to 350 tonnes per hour in materials such as granite, slate, limestone, brick and asphalt. However, the company says that it is also suitable for a wide variety of other applications such as secondary or fine crushing of softer rocks and in various demolition and recycling applications. On show for the first time, following the prelaunch at Hillhead 2010 (UK), the Sandvik QA331 is a three way split screener based on the QA330. The new model has improved screening capacity, and it has been built more durable for the demands of the recycling and contractor market. At the heart of the model lies a 4.27 m x 1.52 m (14’ x 5’) two bearing screen box that possesses an increased 6º screening angle in-built into the bottom deck of the screen. The hopper has a 7 m³ capacity and is complete with a radio controlled tipping reject grid as standard. The main conveyor is fitted with a 1050 mm heavy duty belt and the track width is 500 mm wide. A user friendly feature is a unique folding access walkway fitted as standard around the screen box to provide the operator with easy access for maintenance. Variation on a theme A variation on the QU440 is the QH440 cone crusher developed for the demands of aggregate producers. At the centre of this model sits the Sandvik CH440 cone crusher, which has been used in the applications for over 50 years. It can process material of up to 215 cm and is capable of producing up to 388 tph, at an excellent reduction ratio and cubicity. The machine is designed for ease of mobility, transportation and quick set up time, which means it can be taken to the most remote areas. It features a heavy duty, wear resistant hydraulically folding feed conveyor, dual coil metal detector and is powered by a CAT C13 Tier 3A & 3B Engines both delivering 328 kW (440 HP). It comes with a choice of six different crushing chambers, ranging from fine to extra course, paired with eight different bush settings ranging from 16 mm to 44 mm. The product shape and grading can be easily adjusted by changing the throw to ensure the machine provides the exact quality and quantity of material required, in both secondary and tertiary applications.

Page 12 Contractors World Vol 2 No 5 Show Supplement AT THE SHOWS Bobcat Latest in the M-Series compact excavators Joining the Bobcat M-Series line is the E55 Conventional Tail Swing compact excavator, which fits between the existing E50 and E60 models. The new family member has an operating weight of 5,660 kg (12,478 lbs), an overall width of 1,960 mm (77.2 inches) and is powered by a 36.4 kW (48.8 hp) turbocharged diesel engine that is interim Tier 4 compliant. Although the new model was launched at ConExpo, initially only for the North American market, deliveries will start in July 2011. The company has indicated that it will be rolled out across the world during the year with some minor modifications to basic specifications to suit different regions. The US model comes with TOPS/ROPS certified cab, full climate control (HVAC), and a deluxe high- back cloth suspension seat with retractable seat belt. The “radio ready” cab also includes a 12V power port, adjustable armrests, lockable toolbox and a convenient beverage holder. Within the operator’s area, the new model features convenient “finger-tip” control for boom swing and auxiliary hydraulics functions. Large travel pedals fold up to provide more floor space while flush-mounted floor mats make cleanup easier. A keyless start system that discourages theft and vandalism is available as an option. A fuel saving and noise reduction feature is the ‘Auto-Idle’ function which, when activated by the operator, automatically returns the engine to idle if the excavator functions are not used for a period of four seconds. The engine automatically returns to the preset throttle position as soon as the operator starts working again. For more precise engine speed adjustments, a new easy-to-use rotary knob has been added to the controls. As with all other M-Series compact excavators, a load-sensing piston pump and closed centre valve system provide precise control of the machines travel and work-group functions. An automatic, integrated slew brake holds loads still and steady on slopes for more accurate placement. The need for the operator to manually engage the slew brakes during transport is eliminated, making it easier to load and position the machine for transport. Options available include “pad-ready” steel tracks, rubber street pads, a hydraulic angle blade, second auxiliary hydraulics, hydraulic clamp and Hydraulic X-Change attachment mounting systems for quickly switching between the 16 attachments approved for use on the machine. The E55 has a dig depth of 3.9 m (12 ft 11 inch); reach at ground level is 6071 mm (19 ft 11 inch) and dump height 4,132 mm (13 ft 7 inch). Bucket breakout force in 42 kN (9,442 lbf) and rated lift capacity (over blade at 3 m reach) is 2,268 kg (4,999 lbs). These are provisions figures and subject to change and will,of course, vary according to configuration.

Contractors World Vol 2 No 5 Show Supplement Page 13 Bomag New rollers, finishers, milling machines and more Bomag has kicked off 2011 with new product introductions to the North American market at ConExpo and new products to the European and global markets at Samoter in Italy. This wide range of new products introduction illustrates Bomag’s continued investment in R&D and optimism for 2011 despite subdued demand in Europe. Jörg Unger, President of Bomag said “We think it is more than likely that the market in Western Europe will remain at the previous year’s level. In contrast, the market in Central and East Asia will grow slightly, Jörg Unger, President of Bomag as will many other non-European markets. “In the Middle East, Africa and Asia, the market will continue to grow, although the market has not reached the level before the economic crisis. In China in particular, which is a significant market, the company has paved the way for growth by acquiring its dealer BOMA and introducing new products at its plant in Shanghai. However, the situation looks different on the American continent. While Bomag predicts stronger demand in Canada and some South American countries, such as Brazil and Chile, estimates for the North American market anticipate only slight growth in highway construction and repairs to bridges and roads.” The new BF 800 finisher - world premiere Samoter was the launch pad for the world première of its new finisher model BF 800 - the largest finisher in the current range. It has an operating weight of 20 t and maximum screed width of up to 10 m. Available in track and wheeled versions with 6x6 all-wheel drive as standard and depending on the screed and drive type, the maximum paving width is 9 to 10 m. The new base screeds, S 500 (2.5 – 5 m) and S 600 (3 to 6 m), enable the machine to be adapted quickly to up to twice the basic width. Mechanical attachments are available for larger paving widths of up to 10 m; these can be fitted using simpler quick fit slide couplings. The screeds have electric heating as standard; the heat is evenly distributed throughout the screed plates giving faster heat-up times. Designed for high production, the BF 800 has a theoretical output of 800 tonnes/hour. The high-capacity hopper and the wide bin width make loading easy. A hydraulic front flap, proportional scraper belt, proportional augers and a hydraulic auger height control precisely controls the material flow from bin to screed. The most important functions can be accessed on both sides from new side-mounted operator
The Bomag BF 800 finisher - the largest in the series was launched earlier this year at Samoter. Page 14 Contractors World Vol 2 No 5 Show Supplement AT THE SHOWS stations from which the sensors for the scraper belt and augers can also be selected and controlled. A new feature is the Bomag failure detection system, which detects and indicates inconsistencies and defects in material flow immediately: the operator can take action straight away. The driver’s station can be adjusted in many directions with the Bomag SIDEVIEW system. The entire driver’s station can be extended laterally to an overhang of 50 cm. This means the driver always maintains perfect visibility of the bin, travel drive and screed and always stays protected from the weather. From prototype to production - the BM 500/15 compact planer SAMOTER also saw Bomag announce that it will start selling its new BM 500/15 compact planer and milling drums for other makes of 500 mm class milling machines. The BM 500/15 compact milling machine was first shown as a prototype at Bauma 2010. Bomag say that this is the first compact milling machine that is truly focussed on the operator. Work is controlled from a comfortable sitting position, without health The BM 500/15 compact planer, shown risks due to wrong posture or long-term stress caused by vibration. This is because the as prototype at Bauma 2010 is now in full production. workplace, including all operating controls, is insulated from vibration. All functions can be accessed from a sitting position and a 45º swivel seat provides the optimum view, whether to the loading truck or the milled edge. New milling drum technology The result of three years of research is the wide range of quick-change milling drums for the BM 500/15. These milling drums feature innovative geometry. The teeth are arranged to ensure homogeneous, low vibration cutting. Due to the shell thickness, the milling drum also behaves like a flywheel transferring significantly fewer vibrations to the machine than a conventional drum. The special geometry of the edge cutter generates a smooth edge with a minimum of damage. New diagonal cutters protect the shell tube when working around bends and prevent abrasion to the bracket at the edges. The cutters can be knocked out from the rear quickly and easily. For the contractor, this means longer service life for the machine, less ancillary work, repair costs and greater availability. The new milling drums are not only for the BM 500/15, but also for compact milling machines from other manufacturers in the 500 mm class. New tandem rollers Bomag does not restrict product introduction to trade events. The company has just announced a new generation of vibrating tandem rollers -the ‘Dash 5’ series. The new generation is a significant improvement on the market leading Dash 2 machines that BOMAG has been selling in the UK for over 10 years. There are three new conventional modes available, all in the 1.5 t to 1.7 t class. These new models are the BW 80 AD-5 (operating weight 1,550 kg), BW 90 AD-5 (1,600 kg), and the BW 100 ADM- 5 (1,650 kg). These rollers were announced after the various trade shows. A full review is featured in the main magazine - Contractors World International Vol 2 No 5 of which this supplement is part. A variation of this for the North American market was launched at ConExpo. The BW 900-50 light tandem roller is the newest generation 1 - 1.5 ton ride on roller. Powered by the latest Honda GX630 gasoline engine, it has a working width of 900 mm (35.4 inches) and an overall width of 961 mm (37.8 inches) the machine is flexible for both small compaction applications and larger commercial jobsites. The compact design makes working in restricted areas with tight space clearances easier and safer. Powerful front drum vibration delivers 15.1 kN (3,395 lbs, 70 Hz (4200 vpm) and 0.5 mm (0.020 in) amplitude to ensure the required compaction is met for asphalt as well
The BW 900-50 light tandem roller was introduced to the Bomag range at ConExpo 2011
Contractors World Vol 2 No 5 Show Supplement Page 15 AT THE SHOWS as sub-base materials. A large 137 litres (36 gallon) water tank and a pressurized water sprinkler system with interval flow timer make the BW 900-50 ideal for use on a variety of asphalt applications. The water system is filtered for protection and incorporates an easy drain function for time savings. Asphalt Manager II The latest version of Bomag’s exclusive automatic compaction control for heavy tandem rollers made its North American debut at ConExpo. This intelligent compaction quality control tool provides optimal compaction quality through drum energy vectoring. The appropriate value is displayed in real time to assist the operator in minimizing the required number of roller passes while maximizing density and smoothness. Surface quality is optimized and aggregate crushing can be prevented. The system’s menu guide is designed to make operations simple and efficient. Manual mode delivers exact vector direction for application versatility. Automatic mode allows amplitude limitation for thin asphalt layers. BM 1300/30-2 Milling Machine. The BM 1300/30-2 Centre Rotor Milling Machine is the latest addition to Bomag’s milling machine family and, following launch at ConExpo, is now available to the North American market. With a 1,295 mm (51”) working width, the BM 1300/30-2 features four pivoting tracks, an optimized drive geometry, and extended crawler track columns making it the most manoeuvrable in its class. It also offers several innovative features that provide precision milling, speed and efficiency. The new raised undercarriage supports allow the undercarriage to be extended away from the milling track at full cutting depth, allowing the machine to be levelled on uneven ground or when milling trenches, for greater stability and safety. The water tank has a 25% greater capacity for greater productivity and the operating consoles are designed for easy and intuitive operation. BMP 8500 Articulated Compactor. Bomag also launched to the USA market at ConExpo the BMP 8500 Articulated Compactor which was at Bauma 2010. The remote controlled multi-purpose compactor has enjoyed tremendous success since its launch in 2010. Powered by a 14.46 kW (19.4 hp) Kubota diesel engine, it delivers high compaction output due to its dual exciters and directed centrifugal force. Being remote controlled it can be used in situations such as trenching where the operator can control it from a safe position. To reduce fuel costs,it comes standard with Bomag’s ECOMODE system, which automatically idles the engine during pauses in activity. A unique feature of the BMP 8500 is the bolt-on drum extension which significantly increases the versatility of the machine. With the extensions fitted (on site), compaction width is extended from 610 mm to 850 mm.

The new Komatsu D65-17 tractor dozer - one of two new models introduced at ConExpo
Komatsu America Continued product development to meet North American market demands Although Komatsu is a global brand, the company operates to very strict marketing regions. The products and services introduced at ConExpo are specifically for the North American markets. Some may eventually be introduced in to other parts of the world - or already have. So readers with an interest in any product should check with their local dealer to see if it is available. Contractors World wrote about the company being the first to introduce production hybrid machines and the introduction of their second model - the HB215LC was on show at ConExpo. See preview report. Naturally, there was a lot of interest in the hydrid model but on the stand there was the new dozer, the D65-17, and new articulated dump truck - the HM300-3, the WA380-7 wheel loader and new hydraulic excavators. New dozer series The new line of D65-17 crawler dozers are powered with the more fuel efficient and larger displacement, 8.9 litre, EPA Tier 4 Interim / EU Stage 3B emission certified Komatsu SAA6D114E-5 engines. The new engine demands 5% less fuel than the Tier 3 model it replaces. A standard (EX), low ground pressure (PX) and a wide (WX) track model are available to offer customers flotation and weight distribution options that best match their applications. Operating weight ranges from 44,355 lbs (20,120 kg) to 49,315 lbs (22,370 kg) depending on the version. Developed for heavy dozing and finishing operations, the D65-17 combines the SIGMADOZER blade with a new more efficient automatic transmission with torque converter lock-up to achieve exceptional productivity and fuel economy. A new Komatsu 6-way Power Angle Tilt (PAT) blade is also available for all models, creating a balanced and agile tractor for light and medium dozing operations. The blade also provides precise grade cutting required for site prep, golf course or house pad applications. Newly designed joystick controls gives operators full control, offering a relaxed posture and superb fine control to minimize operator fatigue. Thumb push buttons simplify transmission gear shifting. The pilot controlled hydraulic blade and ripper control joystick offer excellent blade and ripper fine control. The new comfortable working environment allows the operator to concentrate on the work at hand for increased productivity. The new larger cab is now integrated with ROPS (Roll-Over Protection Structure) and moves the standard air ride operator’s seat 3 inches (75 mm) higher and 4 inches (100 mm) closer to the blade for excellent front, side and rear visibility. The interior cab decibel has been decreased to 75 dB(A) for a quiet work environment. A new, large 7” high resolution colour LCD monitor in the cab displays all machine information. Also new in the Komatsu dozer range is the D155AX-7 crawler dozer. The new machine is powered by an EPA Tier 4 Interim / EU Stage 3B emission certified Komatsu engine rated at 354 net horsepower (260 kW). Three new tracked excavators Realising that the hybrid machines are a new phenomenon in the construction sector and not appropriate to every application (they are considerably more expensive to purchase), Komatsu continues to develop the range of tradition hydraulic tracked excavators. ConExpo saw the introduction of three new models - PC240LC-10 weighing 55,000 lbs (24,950 kg), PC360LC-10 at 79,000 lbs (35,833 kg) and the PC490LC-10 with operating weight of 108,000 lbs (48,987 kg). As virtually all Komatsu equipment today, KOMTRAX is fitted as standard and all three models feature an appropriate EPA Tier 4/EU Stage 3B compliant engine. To match the engine,

New WA380-7 wheel loader With a net power of 142 kW (191 hp), the WA380-7 is powered by a Komatsu EPA Tier 4 Interim / EU Stage 3B emission certified engine. Although there is more available power, the new model is up to 10% more fuel efficient than the previous model. Operating weight is 18,100 kg (39,900 lbs) apart from the new engine, other enhancements include a newly designed large capacity torque converter with lock-up as standard. This improves gradient ability and provides a higher speed at lower fuel consumption. The cab has also been further refined with more glass for better visibility/ A high-resolution 7” LCD monitors provides easy to read indication of critical machine functions and allows for the input of operator parameters. A reversing camera is fitted as standard with the monitor mounted on the right of the console for operator convenience. Latest in articulated dump trucks ConExpo was the opportunity to get close up to the HM300-3 articulated dump truck - the latest introduction to the series. Powered by a Komatsu engine that meet EPA Tier 4 interim and EU Stage 3B emission standard, it delivers 242 kW (325 hp). Gross operating weight is 52,230 kg (115,147 lbs) and can haul up to 28.1 tonnes (31 ton) at a maximum speed of 58.6 km/h (36.4 mph). By redesigning the body, the payload capacity is increased and a lower loading height of 2,820 mm (9’ 2”) matches the dump height of 30 - 60 t excavators or 3.8 - 5.75 m³ (5 - 7.5 yd³). The two single stage body lift cylinders provide a 70º dump angle. The Level 2 certified ROPS/FOPS cab features a new curved dash panel with more convenient;y placed switches. The high- back, heated, air-ride seat not only improves operator visibility but is fully adjustable to meet the operator’s convenience. Operator comforts include an auxiliary input for such devices as MP3 music player. There are also two 12 volt ports in the cab for tools and appliances. Through the large LCD display monitor, the operator can modify setting for features such as auto idle shutdown or the auto- reversing fan. The monitor also stores and shows, on demand, driving history, fuel consumption and other performance data. A rear facing camera is fitted as standard with the display unit placed for convenience in the cab.

The Cat 336E tracked excavator with Tier IV interim compliant engine.
Caterpillar An impressive display - what everyone expects and more If there is one stand that is a ‘must see’ at any construction trade event it is Caterpillar as visitors know it will be an impressive display of the company’s strength and almost always has something new to shout about. This year, the company was on home ground and they were expected to do something special and they did not disappoint. What they did was also a surprise as it showed another side to the company - their concern for the environment. However, what draws visitors to the Caterpillar stand is their equipment. Among the many ‘new attractions’ was the new highway truck but there were developments in excavators, rigid dump trucks, wheel loaders, pavers - in fact, something from every product group. Caterpillar did release in advance of the show, details of some of the new products and these were covered in earlier edition of Contractors World and can be found using the convenient ‘search’ function which covers our complete archive. It also has to be remembered that, although Caterpillar is a global company, products are often developed for specific market demands and regulations. Availability and specifications may, therefore vary. Contractors World tries to highlight differences and availability but, of course, these are subject to change. The local Caterpillar dealer should be the first point of contact to see if and when a machine is available. Latest addition to the excavator line-up ConExpo, Samoter and SMOPYC showed how companies are gearing up for the new emission regulations which come in to force soon. And, as to be expected, Caterpillar is no exception. The new Cat 336E hydraulic excavator, which replaces the 336D, has an operating weight of 36,570 - 39,370 kg (80,617 - 86,796 lbs) operating weight, features a more powerful engine that enables higher productivity while meeting Tier 4 Interim emissions standards. Bucket dig force is 184.9 Kn (41,570 lbs) and maximum digging depth is 7.5 m (24 ft 7 in); maximum forward reach 11.02 m (36 ft 2 “) and dump height 7.5 m (24 ft 7”) .[Note: specifications depend on configuration]. With a SAE net power rating of 236 kW (300 hp), the Cat C9.3 ACERT engine delivers 12% more power and 4% faster cycle times than the 336D—all the while improving fuel efficiency by 2%. Greater hydraulic pressure in heavy lift mode boosts lift capacity by 5%, contributing to high productivity when lifting large pipe and trench boxes. Other fuel-saving features include an electric regeneration valve to capture and recycle energy when the boom is lowered. Contractors World, however, has been told that this is not a semi-hybrid solution but a more efficient hydraulic function. Too often, machines are left idling while waiting for trucks or another job to be completed and this is an obvious waste of fuel. The automotive industry has recognised this and many new cars now feature an automatic engine switch-off/restart. Caterpillar now introduces a similar concept. A new engine shutdown setting enables owners and
Contractors World Vol 2 No 5 Show Supplement Page 19 AT THE SHOWS operators to specify how long the machine should idle before shutting down the engine. Additionally, the operator can reduce engine speed to idle with the touch of a button to help save fuel. A isochronous speed control also maintains a constant engine speed regardless of load, and an economy power mode help the operator manage and conserve fuel. Operator station promotes safety and efficiency A new cab safety feature is the addition of a Roll-Over Protective Structure (ROPS). The ROPS provides a seated operator, held by a seat restraint system, with a reasonably protected space in the event of a roll-over. The cab also is sealed and sound insulated and is designed to reduce operator fatigue and allows the operator to work more productively. A new monitor in the cab is 40% larger and provides enhanced resolution. It features quick-access buttons that complement a new screen layout, and can display as many as two camera images. A rearview camera housed in the counterweight area is an option. For enhanced operator comfort, heights of the joystick consoles are adjustable, and the seat cushion is wider. An optional air-cooled Cat 972K wheel loader - one of four new models seat improves operator comfort in warm weather, and a new air introduced at ConExpo 2011 conditioner compressor enhances cab cooling. For greater safety, time delay working lights remain on longer for entering and exiting the cab at night. North American unveiling of the Cat 374D ConExpo was the first opportunity for many to see the 71,132 kg operating weight Cat 374D excavator. Although new to the North American market, Europe first saw the machine at Bauma 2010 and a review can be seen here. Wheel Loader range enhanced with 4 new models The Caterpillar range of wheel loaders has been enhanced with the introduction of the Cat 950K, 962K , 966K, 972K and 980K models. All feature new designs and engines certified to meet Tier 4 Interim emissions standards in the United States and Stage IIIB regulations in the European Union. Improved operator environment The K-Series introduces further improvements to the operator environment across the range. Operators benefit from a cab that is designed to be comfortably and enhance productivity. The cab access steps now have a greater inclination angle making getting in and out easier - similar to stairs instead of a ladder. A wider door opening, better positioned grab bars and a new front-hinged door that can be opened and closed while seated allow for easy entry and exit. Left and right-hand sliding windows can be opened and closed with one hand while seated, making it easier to communicate with people on the ground, adjust natural air flow, etc. A streamlined four-post ROPS design, a new operator position that has been moved slightly forward enhance visibility to the front and sides, while a standard rear-view camera with large colour monitor gives visibility to the rear of the machines. Newly designed viscous cab mounts reduce noise and vibration and an automatic climate control adjusts temperature and fan speed to the operator’s preferred setting. A centre display panel with five analog-like gauges and a large text box displays messages in a choice of languages. A “help” button explains switch functions. Two new membrane switch panels are located on the front right ROPS post. Light-emitting diodes (LEDs) and an audible “click” let the operator know when the switches have been activated. The loaders also feature a new electro-hydraulically activated parking brake. Optional heated and powered mirrors improve operator comfort and clear condensation and ice. AM/FM radios with CD players are available along with a standard MP3 jack and three 12- The Cat 336E has a new monitor in the cab that is 40% larger and provides enhanced resolution. It features quick-access buttons that complement a new screen layout, and can display as many as two camera images.

volt power outlets. An optional communication radio package provides a mounting bracket, antennae and DC/DC converter. It is pre-wired for two-way radios. Advanced engine technology and high efficiency drive train Although the engine rating differs according to mode, all are certified as meeting new emissions standards while improving performance and fuel efficiency. The engines incorporate an upgraded ADEM 4 control module and a new high-pressure common rail fuel system to improve combustion efficiency and reduce emissions. Cat Clean Emissions Modules, securely mounted on its own platform The K-Series wheel loaders from Caterpillar offer excellent above the engine, contains a Diesel Oxidation Catalyst, Diesel Particulate visibility to the front and sides and are well equipped to enhance comfort and productivity. Filter and Cat Regeneration System. Regeneration, the process by which soot is removed from the Diesel Particulate Filter, can be set to take place automatically so that it does not interrupt the machine work cycle, and it can be initiated manually by the operator. To optimize the engine and transmissions lines, the K-Series have new torque converters that have been matched with the engine power curve to save fuel while delivering power increases. The loaders have new transmission shift logic for downshifting into first gear. Now the downshift occurs based on the torque requirements instead of ground speed, which enables operators to use the automatic transmission mode in first through fourth gears. This simplifies operation, reduces dig times and improves fuel efficiency. Also, transmission speed shifts are significantly smoother due to the new shifting strategy that reduces torque losses while shifting. The result is faster acceleration, better ramp climbing performance and improved shift quality. Designed for easier servicing for more uptime Cat K Series Wheel Loaders retain the convenient, one-piece tilting hood introduced with the G Series. However, the rear portion of the hood now incorporates a clamshell design that allows quick access to the engine oil dipstick, oil fill, fuel fill and cooler cores for cleaning. New fold-back external mirrors improve access to a convenient step near the top of the loader tower, and a redesigned window-cleaning platform improves visibility to work tools. The full coverage grab bar around the roof cap provides a secure hand-hold when cleaning windows, replacing wiper blades or inspecting lights. Two ground-level service centres for hydraulic and electrical components permit faster, more convenient maintenance. A look at the performance specifications The Cat 950K and 960K share the same Cat C7.1 ACERT engine delivering a peak net output of 157 kW (211 hp) and 165 kW (221 hp) respectively. Loading capacity ranges from 2.50 m³ to 9.20 m³ (3.25 -12.00 yd³). The Z-bar linkage has been tweaked to improve performance when used with the Fusion coupler and associated work tools. The 950K has an operating weight of 19,087 kg and the 960K is 20,080 kg.
Contractors World Vol 2 No 5 Show Supplement Page 21 AT THE SHOWS The Cat 966K and 972K have respective output of 199 kW (267 hp) and 215 kW (288 hp) with bucket capacities of 2.50 - 9.20 m³ (3.25 - 12.00 yd³) for the 966K and for the 972K capacities from 2.90 - 9.90 m³ (3.75 - 13.00 yd³). Generous breakout forces (196 kN /44,076 lb on the 972K), give aggressive material penetration for shorter cycle time. The Cat 980K has an operating weight of 30319 kg (66823 lb )and is powered by the new Cat C13 ACERT engine with peak net power of 275 kW (369 hp) at 1500 rpm. The loader accommodates buckets from 4.00 to 12.20 m³ (5.25 to 16.00 yds³) and, with a breakout force of 238 kN (53475 lb), is designed as a productive and cost effective tool in quarry, aggregates, construction and other high-volume applications. Maximum travel speed is 35.8 km/h (22.4 mph). Caterpillar Keep on trucking No show would be complete without Caterpillar rolling out a new off-road rigid dump truck and ConExpo was no exception. However, joining the new off-highway truck was the latest generation in articulated dump truck and the North American unveiling of the much anticipated highway truck First in a new series of rigid dump trucks Coming in close to the top of the range of Caterpillar off-highway dump trucks, the Cat 77G is the first model in the G-Series. So what has improved? Caterpillar says that “The new Cat 775G sets new performance standards for the model while meeting US EPA Tier 4 Final emissions standards. A combination of new drive train strategies and a 5% power increase over the previous model enable the 63.5 tonne (70 ton) payload class truck to hold a higher gear when climbing 10% grades in most applications.” There are a number of new components and control changes boost efficiency that are obviously designed to integrate with the modern engine management system for optimum power conversion. A key is the next generation of Cat transmission controls, named Advanced Productivity Electronic Control Strategy. The system enhances productivity, fuel efficiency and drive train durability, enabling enhanced machine control. Advanced control systems also integrate the optional engine compression brake with Automatic Retarder Control to enable faster downhill travel and reduced cycle times―without increased fuel consumption. To meet Tier 4 Final emissions regulations in the USA, the Cat C27 ACERT engine includes the Cat NOx Reduction System and Diesel Oxidation Catalyst. Working in combination with ACERT technology, the Cat NOx-Reduction System continually diverts and cools a small volume of the engine exhaust gases, then returns the cooled gases to the combustion chamber. This process reduces cylinder temperatures and, consequently, lowers NOx formation. The no-maintenance Diesel Oxidation Catalyst reduces certain hydrocarbons in the exhaust. Because the system requires the use of ultra low sulphur diesel fuel and does not use a diesel particulate filter, in the European Union and other areas, it will be configured to meet EU Stage II emissions standards, which is the EU regulation
The new B Series articulated dump trucks from Caterpillar now include the 735B, offering a 36 ton (32.7 tonne) payload,
Page 22 Contractors World Vol 2 No 5 Show Supplement AT THE SHOWS
applicable to the power output of the engine. Net power is 581 kW (779 hp), and target gross weight of the truck is 111,811 kg (246,500 lb). As with the previous model, a number of different body options enable a customer to configure a truck to achieve optimum capacity and durability. The 775G will replace the 775F when it goes into commercial production in the fourth quarter of 2011. Top speed is quoted as 67.6 km/h (42 mph) A new cab and other changes help the operator do the job safely and efficiently. The operator seat is in the centre of the cab, which provides more space for the operator, and the cab has access from either side. The access system is equipped with stairs illuminated by LED lights. The new cab is quieter - by a 4 db(A) reduction in noise experienced by the operator. The left window is electrically powered, and the cab heating and cooling features automatic temperature control. For more uptime, fluid level indication and fluid fill ports are grouped for efficient service, and fluid filters are grouped. Filter service intervals for steering, hoist/brake, and transmission/torque converter have been increased from 500 to 1,000 hours. Life gets easier for ADT operators with the new B-Series from Cat The new B Series articulated dump trucks from Caterpillar now include the 735B, offering a 36 ton (32.7 tonne) payload, the 740B with its 43.5 ton (39.5 tonne) payload, and the 740B EJ with popular ejector body, carrying a 42 ton (38 tonne) payload. As this is the global launch, all three models are available with either Tier 2/Stage 2 equivalent or Tier 4 Interim/Stage IIIB certified emissions configurations to meet the needs of customers. Both configurations feature revised transmission and traction control systems that enable higher productivity. The new trucks also focus on reducing driver effort and cutting operator fatigue through improved cab design. The systems employed on the Tier 4 Interim/Stage IIIB B Series trucks produce 90% less particulate matter (PM) and reduces nitrous oxides (NOx) emissions by as much as 50 percent. Emissions controls include a Diesel Particulate Filter (DPF) to trap soot. The necessary process of removing the soot is called regeneration. Optimized drive train To maximise the power and efficiency of the new engines, Caterpillar has improved its six-wheel-drive system. A new, fully proportional torque-distribution automatic traction control (ATC) system eliminates the need for any driver intervention to maintain maximum traction in difficult operating conditions. With the new proportional ATC system, the truck automatically and constantly varies the required proportion of lock- up on both cross-axle and inter-axle diff locks as underfoot conditions change. The automatic system leaves the operator free to concentrate on driving the truck, without having to think about how to gain the best traction. The new proportional
The ‘old and new’ - the latest in Cat rigid dump trucks alongside the all new highways truck from Caterpillar AT THE SHOWS
The new US vocational truck from Caterpillar was unveiled at ConExpo.
ATC system works in harmony with the hydraulic steering system—without compromise, in tight turning manoeuvres. The optimized proportional ATC system results in improved traction in all operating conditions for reduced cycle times and improved productivity. The automated system also reduces the possibility of system abuse, cutting wear as well as prolonging component life and reducing costs. Improved operator environment Sitting in the cab of an ADT all day, especially when much of the travel is over very uneven ground is both taxing and uncomfortable - regardless of the air suspension seat. Caterpillar has tried to address this issues and says that the B Series trucks are designed and built around the operator. Behind the tough exterior, with its powerful new styling, integrated heavy-duty bumper and fully enclosed belly guards, the Cat truck offers an improved operator environment. A new injection moulded dash panel with revised trim provides an improved fit and a more aesthetically pleasing working environment. The redesigned instrument cluster and multi-purpose display give the operator all of the information needed. Machine monitoring includes information as diverse as regeneration status, fuel levels, autolube status, load count and major component temperatures. It also incorporates a live feed from the rear view camera, which is automatically engaged when reverse gear is selected. An upgraded driver’s seat with new multiple position adjustments improves the ride quality further, while new materials offer improved durability and long service life. A heated driver’s seat is available as an option. New operator and passenger grab handles improve stability when travelling over rough or sloping terrain. On the road again - Caterpillar highway truck for North America A significant new product launch for Caterpillar is the Cat CT660, the first model in a full line of Class 8 vocational trucks designed to work as transit mixers, refuse haulers, dump trucks and in any application requiring a heavy-duty truck with the reliability, durability and low cost of ownership characteristic of Cat products. “This is an exciting historic milestone for Caterpillar,” said Steve Gosselin, vice president of customer services support division. “The CT660 is a natural expansion of the Cat product line and a perfect complement to other Cat equipment on the jobsite. The truck is a direct result of Caterpillar’s commitment to continuously developing new products that accelerate the business success of our customers—and its design results from hundreds of hours spent with vocational truck owners, fleet managers and drivers to determine their specific needs.” The trucks were received with the same enthusiasm as the launch in Australia which took place a few months ago when the first-ever Cat on-highway trucks - Cat CT610 and Cat CT630 - received an enthusiastic response from more than 300 people in attendance at a launch event in Uluru, Northern Territory, Australia. Read more The new products were developed by NC2, the joint venture between Navistar and Caterpillar. “These ground breaking new on-highway Cat trucks demonstrate the unique value proposition that NC2 is delivering to the global truck marketplace,” said Al Saltiel, president of NC2, speaking at the Australian launch. “We are proud to be bringing these new trucks to Australia, leveraging the potent combination of Navistar’s truck manufacturing expertise and Caterpillar’s powerful global network.” “Our goal was to design and manufacture the ideal truck—the truck that customers have always wished they had for specific vocational applications,” says George Taylor, director and general manager of the Caterpillar Global On-Highway Group. Caterpillar is obviously pursuing this line aggressively as they have already announced that the second model in its new line of on-highway Cat Vocational Trucks, the Cat CT680, will be available first quarter 2013. A Class 8 truck, it will be built in America and sold and serviced exclusively through the North American Cat Dealer network in the United States and Canada.

Production of the new models for markets in North America and Europe began at the end of March 2011. Cranes, with lifting capacities ranging from 60 to 250 tonnes for Europe and 85 to 275 U.S. tons for North America, have been newly designed, upgraded and improved from the customer’s point of view with safety, reliability and efficient operations in mind. Maximum lifting capacities ranging from 60 tonnes through to 250 tonnes. Depending on model, the basic boom length is 12.19 m (40’) to 15.24 m (50’). Maximum boom length plus fixed jib length ranges from 54.86 m (180’) + 18.28 m (60’) through the different models to 76.20 m (250’) + 30.48 m (100’). The larger three models can also be configured with luffing jib. All are powered by Hino engines developing from 213 kW to 271 kW and comply with current emissions standards as applicable to North American and European markets. New features To comply with latest emissions standards, all models are equipped with engines compliant with EPA Interim Tier IV and EURO stage IIIB. Rated output of the new engines has been upgraded from the previous series and tuned for optimum performance in crane operations. The efficiency of the new engines results in a fuel saving of up to 30% compared to previous models. A contributing factor was a totally new energy-saving assist system on all new models. Called the “G MODE” system, it assist systems such as Auto Idle Stop System, Energy Saving Winch Control System and Engine rpm Limitation System. • Auto idling stop function This function will stop the engine automatically during idling time under certain conditions. Immediate restart is possible by controlling the accelerator grip. • Energy saving winch function: This function enables the hoist winch to be turned at maximum speed without engine accelerating under no-load lifting. • Engine rpm limitation function - function to reducing the engine rpm range while enabling optimum performance in normal mode. For easier transport, the new models have a minimum width of 2.99 m and modules of 45 tonne or less. Not only does this simply set up for transportation but also eliminates the need for an escort car or special permission, in many instances. An optional feature is a new safety support device. This system monitors three aspects. The counterweight detection device always shows the correct amount of the counterweight. A swing angle detection device prevents over-swinging, while the ground level sensor prevents operations on uneven ground. Machine status is displayed on a new wide monitor in a newly designed operator cabin designed to allow the operator to work productively while sitting in comfort and safety. As if often the case when using the latest engines, to maximise performance it is also necessary to change associated systems such as transmissions and hydraulics. The new Kobelco range has had the hydraulics upgraded to be more e adaptable to work in both operating configurations - with a bucket and in lifting job applications.
Kobelco Cranes Prototype mini excavators from Kubota on show Samoter saw the Kubota showing two prototype machines amongst a display of existing models. Contractors World was told that the KX016-4 and KX019-4 mini excavators feature a larger cab and a longer arm for increased reach and digging depth. The 1540 kg KX016-4 has a bucket capacity of 0.035 m³, an engine rated at 9.6 kW. Maximum dig depth is 2.25 m, forward reach 3.79 m and dump height 2.29 m. The larger model has an operating weight of 1,780 kg and an engine rated at 11.8 kW. Maximum dig depth is 2.58 m, forward reach 4.07 m and dump height 2.56 m. Both models are available with canopy of fully enclosed cab and feature a digital display panel in the arm rest, There was no indication of when the machines will be available

Page 25 Contractors World Vol 2 No 5 Show Supplement Link-Belt Lots of changes across the ranges ConExpo was the show ground for the American crane manufacturer, Link Belt, to make several announcements. Among the new introductions was the company’s all new 275 ton (250mt) ATC-3275 all terrain crane. This model is the first all terrain crane engineered with a focus on the North American market and has been developed around customer feedback. It meets the toughest transport laws in North America while also meeting Tier IV Interim and EPA 2010 on- highway requirements. Link Belt claim that the ATC-3275 marks the first time a modern AT crane has been designed and manufactured in and for North America. Critical to any market is the ability to transport. The 3275 breaks new ground with its modular counterweight system. None of the weights is more than 22,000 lbs (9 979 kg) and can therefore be grouped together or with other components on transport trucks to maximize the loads. The 3275 with maximum counterweight, rigging, matting, and fly extensions can move with just four truckloads. Link-Belt expands its telescopic crawler line The 110- ton (100 tonnes) TCC-1100 telescopic crawler crane is third in a growing lineup of Link-Belt telescopic crawlers, strengthening the company’s presence in this rapidly growing market niche. According to the company, the TCC-1100 offers an impressive capacity chart at radius that rivals even lattice crawler cranes with a similar base rating. The main boom is 150 feet (45.7 m) long and incorporates Teflon wear pucks to eliminate boom grease. Fly options include a 31–55 ft (9.4–16.7 m), three-piece bi-fold lattice fly and a 10 ft (3 m) heavy-lift fly. The heavy-lift fly swings and pins into place and is integral to one of the on-board fly options. It has over 20 tons (18.1 tonnes) of capacity and lift procedures for two-load-line picks. All flies offset to 2, 15, 30, and 45º. New crawler The 150 ton (137 tonnes) 238 HSL a completely new model that joins the 138 HSL, 218 HSL and 298 HSL in the Link- Belt lineup. Designed for the general contractor, the new model will see action in steel erection, bridge work, pile driving and more. The crane comes standard with folding upper guardrails and full-length right and left catwalks with grab handles. A rear-view, high-resolution camera and a colour screen in the cab helps the operator stay up-to-date on jobsite conditions while an outside travel alarm helps keep the ground crew informed. Power is via a 286 hp (213.3 Kw) Isuzu 6HK1 engine with interim Tier IV DPF, which Link-Belt independently tested the new after-treatment system to help ensure critical uptime while producing reliable, clean-burning power. The proven Link-Belt hydraulic pilot operated control system directs and regulates flow to deliver millimetres when needed—every time and with great feel in the levers providing valuable feed back to the operator. The hydraulic cylinders detach in one piece with the base counterweight to reduce the weight of the main transport load. The upper counterweights consist of a 20,000 lbs (9,071.8 kg) “A” counterweight and six 15,000 lb (6,804 kg) biscuit counterweights. The 238’s main boom length is 50–260 feet (79.2–15.2 m). A fixed jib ranges from 30–80 feet (9.1–24.4 m) and maximum tip height is 310 feet (94.5 m) with a 230- plus 80 ft (70- plus 24.4 m) combination. A luffer will also be available. New truck crane On show for the first time, the HTC-86100 truck crane has a 35–140 ft (11.6–42.7 m), five-section, formed boom. Maximum tip height is 237 ft (72.2 m) with the additional two 16 ft (4.9 m) lattice inserts that can be installed between the boom head and the fly. Onboard tip height is 205 feet (62.5 m).
