Abstract: The invention describes a method and a position control system (22?) for controlling operation of a computer-controlled load handling device, with a displacement drive for a displacement unit, a lift drive for a vertically displaceable lifting unit and an actuator drive for a loading and unloading device, and a computer predefines a target position for the displacement and lifting units and loading and unloading device and controls the travel to it. Time-minimized reference trajectories are set first of all, optimized with respect to the maximum permissible loads of the load handling device and with respect to the displacement between the start and target positions, and from these, the desired trajectories are calculated for desired positioning forces (Fxsoll, Fysoll, Fzsoll) of the displacement and lifting units and the loading and unloading.

Abstract: The invention relates to a device (11) and a method of regulating a temperature of a drive element (2) which can be employed in a deep-freezing application in particular, such as a band, belt or similar, in which at least a part-region of the drive element (2) is heated at least during a relative displacement between the drive element (2) and a machine part. The drive element (2) is adjusted to a pre-definable minimum temperature and a pre-settable minimum temperature is maintained. To this end, the device (11) has at least one module (12), which supplies the drive element (2) with mechanical, electrical or electromagnetic energy, for example.

Abstract: The invention relates to a method of storing and retrieving load-bearing units (16) and a conveyor trolley with a load-bearing means (12) to accommodate a trolley (21), having a platform (40) for receiving a load-bearing unit (16), in particular a pallet, as and when necessary, which is equipped with bogie assemblies (30) with height and lateral guide elements (31) for storing and retrieving the load-bearing unit (16), and the height guide elements (31) are displaceable along at least one guide track (23) on the load-bearing means (12) and are linked to at least one displacement drive (30) to initiate the displacement motion of the load-bearing means (12), and the displaceable platform (40) is linked to a drive (41).
