Shuttle type shelves generally use pallets as storage units, which is a more advanced space use scheme, suitable for first in, first out and first in, second out operation. The specific implementation process is that the forklift will place the shuttle and goods to the required operation channel, and through the remote control, the shuttle will independently complete the lifting and driving of goods, and send the pallet to the designated location. The position of the stored tray is identified by the sensor. During pallet access, there is no contact between pallets. Shuttle type shelf is characterized by high utilization rate of warehouse space and good system stability, especially suitable for the storage of large quantities and single varieties of goods such as food and beverage, cold storage, fast-moving products and third-party logistics industry.
