MORE POWER, FASTER CYCLE TIMES AND LESS FUEL CONSUMPTION FOR MORE APPLICATIONS • MORE PRODUCTIVITY with NEW 20 Ton model • LESS FUEL CONSUMPTION & EMISSIONS with NEW Tier IVi SCR technology • HIGH RELIABILITY with NEW Heavy duty axles • FAST CYCLE TIMES with NEW five-speed transmission AT THE SHOWS 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. Roger Lindley Publisher/Editor AT THE SHOWS 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 Page 6 Contractors World Vol 2 No 5 Show Supplement AT THE SHOWS – 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.
