Abstract: A telescopic arm of a load-handling system for transferring storage units into and out of a rack stage of a racking system is displaceably supported on a support frame and has a plate-shaped middle slide and a plate shaped top side displaceable relative to the support frame and to each other. The support frame is in the form of a hollow section and has first and second upright longitudinal side walls and a bottom and a top side wall. Lateral guide tracks and a vertical guide track are arranged on the first upright longitudinal side wall. The top slide has lateral guide tracks and a vertical guide track as well as movable drivers for pushing a front or rear face of the storage unit. The middle slide is slidably guided between the support frame and top slide.

Abstract: The invention relates to a load-bearing frame (18) for a conveyor device, in particular a shelf-stacking device (1), with a support frame (19) which can be secured on a lift (17) of the conveyor device and, disposed on it, mutually parallel support mechanisms with displaceable telescopic support arms for receiving a storage unit such as a pallet (6), box, etc., and a conveyor system forming a conveying direction extends parallel with a displacement direction of the support mechanisms (21). The conveyor system consists of conveyor mechanisms (27) with two linear conveyors (26) arranged in pairs, disposed symmetrically by reference to a mid-plane (31) and extending between the support mechanisms (21) perpendicular to the standing surface (8) of the shelf-stacking device (1), forming a conveyor direction parallel with a displacement direction of the support mechanisms (21).
