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.
A load-handling device comprising a carriage (21) adapted for movement on a floor, and a load-handling assembly arranged on said carriage and including a cam track, a driving mechanism and a load-engaging member (29) which is driven by said driving mechanism and is vertically movable as well as extendable and retractable relative to said carriage, said driving mechanism of said load-handling assembly comprising a first endless driving element (34) which is adapted for movement along a path between spaced-apart guides (33, 35) and a driving member for driving said driving element, said load-engaging member (29) of said load-handling assembly including a first and a second arm designed as a double-armed lever (29, 30, 39) with a fulcrum (40) that is rotatably connected to the first endless driving element (34) so as to follow the movement thereof, and said first arm (29) constitutes at least a portion of the load-engaging member (29), and said second arm (30) has a cam follower member (38) which, for the purpose of absorbing torque, is arranged to cooperate with and abut against said cam track (36, 37) included in the load-handling assembly.
