The mobile shelving system includes a tray or cantilevered rack mounted on a mobile base. The motor drive base is used to drive the shelf to move along the track, and the position where the goods need to be stored/extracted is used as a passage. This saves 9 to 10 working channels and creates new storage space. They can be controlled on the shelf or controlled by a remote control. Safety opto-electronic devices on both sides of the shelf channel initiate an emergency stop when the shelf encounters an obstruction. advantage: Save more than 90% of the shelf channel Higher space utilization Automatic control FIFO can be achieved
