The prototype arrives in Wilmington, North Carolina, from manufacturer IHI of Japan in March (when US-made boom sections will be fitted). The prototype will be delivered in May. The company plans to bring in 20 more in 2007, according to product manager Mark Swartz.
The crane fills the gap between the 165 US ton (149t) HC 165 and the 275 USton (249t) capacity HC 275.
It can be used for different types of work: it has a single-sheave offset tip and a six-sheave hammerhead tip. Freefall is available on main and auxiliary drums, and a third rope drum is an option. The crane will also feature a heavy-duty load chart with an optional 64,000 lbs (29t) more upper and carbody counterweight, for a total of 192,000 lbs (87t). The initial launch will not include a luffing jib, although one is currently being planned, Swartz says.
Standard features include an LMI with interactive screen and shockless stop system, adjustable seat, air conditioning, radio, overhead window, fan, overhead and front wipers and drum rotation indicators.
Hydraulic cylinders set inside the carbody extend and retract the crawler side frames. The crane has 48in (1.2m) wide crawler shoes. The open-circuit hydraulic system has two variable-displacement piston pumps for travel and hoisting, and three gear pumps power swing, hydraulic cylinders, and pilot pressure. With 260ft (80m) of boom, the crane breaks down into nine truck loads.
