Add gravity roller track and slight slope Gravity Racking so that the tray can slide. It is introduced at one end of the higher track, and the goods are slid to the other end by gravity and velocity control, from which the goods are extracted.

 The first-in-first-out storage system is adopted to make the movable storage complete product turnover and carry out the first-in-first-out operation of the tray thoroughly. This trait is ideal for short-term storage.

 This system can be applied to the manufacture or sale of products in any industry (food industry,automobile industry, pharmaceutical industry, chemical industry, etc.), and its huge advantages provide great flexibility.
