Carbody connection system and crane using same

摘要

A mobile lift crane (10) includes a carbody (12) made from two side members (11) and two end cross members (13) connected to each other with a carbody connection that can be disconnected such that the side members (11) and end cross members (13) can be individually transported between job sites and reassembled at a new job site. Preferably the two side members (11) are interchangeable with each other when making the carbody (12) , and the two end cross members (13) are also interchangeable with each other. Further, each of the side members (11) and end cross members (13) preferably has a section of a roller path and section of a ring gear (31) attached to them while being transported and assembled.
