Abstract

The invention relates to an apparatus (1) having at least one supporting surface (3) for containers (4) and having a device. This device serves to load or unload and comprises a part (11), which can be slid onto the supporting surface (3) and withdrawn therefrom and which has a drive (12) therefor. The drive (12) consists of at least one drive wheel (44, 45), an articulated system (42, 43) and of a winding system (46, 47) for the articulated system (42, 43). The drive wheel (44, 45) can rotate about an axis (40), which extends approximately perpendicular to the direction of motion of the part (11). The winding system (46, 47) is situated in the plane of the drive wheel (44, 45).
