Abstract
Abstract The installation comprises an endless circulating shelf plant which is divided into a plurality of individual endless bucket belts having run returning stations with horizontal run returning axis in a common plane. A shelf serving apparatus is located in front of this plane and can access every location of the shelves of the individual endless bucket belts which arrive in the mentioned plane. Due to the combination of the endless circulating shelves and the shelf serving apparatus the access time is substantially optimized by the installation which also utilizes the available space to its best.
