Gravity rack is a high-density and low-power mode of storage. The bottom of rack is a slope and is made of steel drums. Pallets of goods are sliding by its own gravity. Speed controllers are interluded in ordinary rollers. The sliding speed of pallet is controlled by speed controller. There is safety separator at the exit of roller lain. It separates the first tray from the latter one automatically, thus forklift can remove goods from rack easily. Different designs can achieve FIFO and LIFO mode.
FIFO-style: Goods are stored on one end of the racks and removed from the other end, requiring only two operating channels to achieve FIFO, particularly applicable to food, pharmaceuticals, beverages, chemical industry, etc.
LIFO-style: Goods are stored and removed form the same end, requiring only one operating channel.
