Pallet Live Storage Flow Racking is high density and low energy consumption storage system. The pallet is supported by steel rollers. The pallets slide down from entrance side to exit side along the sloping roller conveyer. The brake installed in the roller system can control pallets sliding speed. The safety separator can separate the first pallet from the following one at the exit side so that forklift can easily take away the pallets. By this way, first-in-fist-out working mode can be realized. Due to this working mode, Pallet Live Storage Flow Racking is widely used in many industries which have requirement on guarantee period, such as food, pharmacy, beverage, chemistry and so on.
