A stacker crane-operated automated storage and retrieval system (AS/RS) and four-way parking garage are constructed for dense storage. The tracks of the four-way parking garage are directly connected to the stacker crane warehouse. During loading and unloading, four-way vehicles retrieve and place goods at the stacker crane's docking point, and then the stacker crane handles the inbound and outbound operations.

Chain conveyors are installed at the inbound and outbound entrances of the stacker crane warehouse. After the stacker crane places goods on the conveyor line, the system calls an AGV to retrieve the goods from the conveyor line and deliver them to the human call point. Humans use PDAs to request goods and return materials to the warehouse, while AGVs handle the transfer of logistics within the workshop. The AS/RS is used for material storage.
