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.

Abstract: A lifting and turning device for work objects comprises a stand (14) and a holding frame (10) which is supported thereby and in which the work object is fixable. The holding frame is connected in a vertically adjustable as well as turnable manner with the stand. Driving elements are provided for lifting, lowering and turning the holding frame. According to the invention, the holding frame (10) has parallel driving and idling wheel tracks (12, 13) which have curved corners and, connected thereto, straight portions extending substantially perpendicular to one another. Furthermore, the device has a driving wheel (15) and an idling wheel (17), respectively, engaging the tracks (12, 13) and being provided at a distance from one another as seen in the direction of the tracks, one on the inside and the other on the outside of the parallel tracks. The wheel (17) on the inside is disposed on a higher level than the wheel (15) on the outside.
