Abstract
An adjustable system for lifting and transferring load containers which comprises a frame, a container lifting device, and a cable attached to the frame and lifting device. A first actuator is provided for raising and lowering the lifting device, which lifting device has a plurality of remotely controllable latches for engaging and disengaging latchable portions of the containers, to permit grasping and lifting of containers by the lifting device. New features of adjustability are provided, to permit the system to lift containers of varying sizes. Also, the lifting device preferably carries an electrically operated location sensing device for sensing and signalling to the operator a proper location of the latches relative to the latchable portions, to permit such latching.
