Abstract
A mobile crane with rotating bed, mast, gantry and gantry backhitch is arranged for disassembly and ease of transport without unreeving the boom hoist rigging by collapsing the backhitch, folding the gantry back onto the backhitch, pinning together the backhitch, gantry and boom hoist assembly -- which includes the boom hoist drum and motor, and releasing the gantry, backhitch and boom hoist assembly from the rotating bed. A bracket is fixed to the gantry to provide an anchoring point for the equalizer assembly normally secured to the boom.
