Chicago-area crane-rental operation, Stevenson Crane, has demonstrated setting up the 120-ton Liebherr LTR1100 with only a 10-foot assembly jib in 30 minutes. The telescopic crawler crane transports on three truck loads, and requires no set-up crane. Retracted, the telescoping track units offer an overall width less than 11 feet. On-board jacks simplify track removal for a transport width of less than 10 feet. The LTR1100 has a 172-foot telescopic boom and can be used with two 23-foot boom extensions. The angle of the optional swing-away jib can be adjusted hydraulically under full load to as much as 40 degrees.
