ABSTRACT:
A lightweight, self-powered, transportable crane assembly is disclosed which includes a frame that can be selectively coupled to and uncoupled from the bed of a transport vehicle or carrier, such as a pick-up truck or trailer. The frame assembly also includes stabilizing legs which can be extended laterally from the frame assembly to stabilize the crane during use and further to allow the crane assembly to be self supporting apart from the truck or trailer. The crane assembly also can be coupled to a ballast structure such as a water tank or the like, to permit its use apart from the transport vehicle.
