CA 2520755

A heavy lift crane is mounted on a trailer for towing by a highway tractor; with a hydraulic pump and its driving motor mounted for rotation with the crane, with direct connection to the crane primary systems, enabling unimpeded slewing. The crane outriggers are powered by an auxiliary motor and pump, located on the trailer, with outrigger controls operable from ground level. An additional pair of outriggers enable safe use of the crane to position outrigger support pads for the outriggers. Access stairs and catwalks give the operator safer access. The construction format leads to lower cost structures with enhanced serviceability and safety.
