ABSTRACT:
A load-handling device is designed as a carriage movable along a floor and having a load-handling assembly whose load-engaging member is vertically movable as well as extendable and retractable relative to the carriage. According to the invention, the driving mechanism of the load-handling assembly comprises an endless driving element which runs along an elongate path between guiding wheels. The load-engaging member of the assembly is designed as a double-armed lever. The fulcrum of the lever is rotatably connected to the driving element so as to follow the movements thereof. One arm of the lever constitutes the load-engaging member or forms a part of the load-engaging member. The other arm of the lever has a cam follower. The cam follower serves to absorb torque produced by the load and, to this end, engages a cam track.
