Abstract
The invention provides a storage device with storage racks and a shaker where the undesired horizontal oscillations of the upper ends of the storage racks are small. For this purpose, rotating bodies with non-horizontal end faces are provided, each of which is contacted by a follower member, with the follower member carrying out an up and down movement when the respective rotating body rotates. In a second embodiment, a moving counterweight assembly is provided that counteracts the oscillations. The counterweight assembly is connected to the upper end section of the storage racks and includes a vertically displaceable counterweight. The counterweight is mounted eccentrically on rotating tables.
