ABSTRACT:
A crane has an upperstructure that is mounted on a carrier by a quick-disconnect turntable mounting. The upperstructure can be transferred from the carrier to a transport, and back to the carrier, by a system that does not require an auxiliary crane. A live mast on the crane is used for positioning a front lift assembly and a rear lift assembly for attachment to the upperstructure. The front lift assembly is connected to the upperstructure frame by boom foot pins, and the rear lift assembly is connected to the frame by the counterweight mounting mechanism. These lift assemblies enable vertical movement of the upper structure, and outrigger jacks on the carrier enable vertical movement thereof. Air pad assemblies are provided between the outrigger jacks and the surface supporting the carrier. These air pad assemblies can also be provided between the lift assemblies and the surface supporting the upperstructure. These assemblies enable horizontal movement of either the carrier or the upperstructure with minimal frictional resistance.
