The Cat® C6.6 ACERT engine is an excellent choice for Link-Belt cranes — now and in the future. Extending toward the sky and the future

t takes years of experience to develop the expertise to design and manufacture cranes that lift heavy loads several hundred feet in the I air. And it takes a special kind of know-how to design cranes that perform these functions in rough-terrain environments. Link-Belt, head- quartered in Lexington, Ky., has the process down to a science. As a crane manufacturer with more than a century of experience under its belt, the company currently manufactures an entire line of mobile telescopic and lattice boom cranes. For the power needs in its rough-terrain and hydraulic truck cranes, Link-Belt has turned to Caterpillar industrial diesel engines.

diverse application Link-Belt currently uses the Cat® C6.6 ACERT engine in its RTC-8065 Series II and RTC-8090 Series II cranes and the Cat 3126B in its RTC-8075 rough-terrain crane. The Cat C11 ACERT powers Link-Belt’s HTC-8640SL and HTC-8660 Series II hydraulic truck cranes (on-highway cranes). The application for these cranes is diverse, from construction to material handling to equipment rental — in both on- and off-highway models. A main difference between the rough-terrain and hydraulic truck cranes is their travel speed and mobility. The hydraulic truck cranes are made to travel down the highway at 55 to 60 mph while the rough-terrain models’ top traveling speed is around 20 mph. The rough- terrain models are equipped with off-road tires and tend to be operated for longer periods of time on a single jobsite, often on a long-term rental basis. The hydraulic truck cranes, due to their mobility, can travel to multiple jobsites in a day.

The engine is rated at 167.8 bkW (225 bhp) at 2,200 rpm. 4 Industrial Engine Power Report • SPRING 2007 Regardless of application or model, the Uniform power requirement cranes’ engine powers both the drivetrain and Link-Belt’s newest Cat engine is the C6.6 the hydraulic system.

Industrial Engine Power Report • SPRING 2007 5 ENGINE TECHNOLOGY

® CAT engines with acert™ technology

rom the very beginning, Cat® engines have been Fon the cutting edge of technology. For example, Caterpillar introduced electronic engine control — and turbocharging — years ago. That innovative spirit continues today in Cat engines with ACERT™ Technology. ACERT Technology began as a better way to reduce diesel engine emissions, and it has culminated into a revolu- tionary engine design breakthrough that actually enhances diesel engine performance by burning fuel more precisely. The key to ACERT Technology is injection timing. Instead of injecting fuel in one burst, ACERT Technology delivers fuel in a series of smaller microburst injections. As a result, Cat engines with ACERT Technology are pro- grammed to achieve maximum performance and efficiency with lower combustion temperatures, which reduces emissions and prolongs the life of lighter, more power-dense engine platforms. ACERT Technology also varies the injection timing based on factors like engine load and speed. This allows the engine to maintain optimum performance under a wide range of operating conditions. As technology advances, Cat engines with ACERT Technology continue to remain ruggedly durable, reliable and cost-efficient. Caterpillar continues to leverage technology to boost performance and efficiency, while retaining operational simplicity, reducing emissions and maintaining long service life. And the unparalleled worldwide Cat dealer network continues to back it all up. •
