In the logistics industry, high-bay warehouses are rack systems that are between 12 m and 50 m high and built in silo design. They are characterized by large storage quantities and space utilization up to ceiling height. As a rule, the storage concept is electronically controlled. Goods are stored and retrieved by automatically controlled computers. Warehouse personnel or digitalized transport systems take care of incoming and outgoing goods at predetermined delivery points. In high-bay warehouses, there are different zones. There is a storage area where the goods are located directly for storage, the pre-zone with an infeed and storage area for receiving the goods and the outfeed area for delivering the goods.
Fully automated and with few personnel
The storage of flat goods and long goods is possible with a high rack. It is also used, for example, for sensitive goods such as electrical appliances. High racks are very clear, but the investment of this type of rack, especially the fully automatic ones is very expensive. However, a saving is made in the required warehouse personnel. Loading and unloading of high-bay warehouses is usually done with forklifts, roller conveyors, automated guided vehicles, etc. In automated systems, the storage areas are closed off to personnel for safety reasons. IT systems are used to coordinate the goods processes.
