After the transport orders are entered, the Storage and Retrieval Unit brings the system pallet – including the material – to the preliminary storage bay.
The scissor lifting table with the lifting and lowering position retrieves the pallet from the preliminary storage bay and transports it outside for removal of the material. During this time, the Storage and Retrieval Unit (SRU) brings another pallet to the now-unoccupied preliminary storage bay.
The lowest rack, made of steel, serves as a return storage station. After the "return storage" order is issued, the scissor lifting table travels into the safety area and deposits the pallet in the lowest rack, the return rack. The SRU accepts the system pallet and again stores it in the storage tower. After the SRU has retrieved the pallet and placed it in return storage, the scissor lifting table retrieves a pallet from the preliminary storage bay and transports the new system pallet outside.
- Quicker material provisioning cycle because the storage pallet is already located at the preliminary storage bay
- Possible for loading and unloading cycles
