Push Back Rack Systems are defined as being a high-density pallet storage system. This particular system allows for pallets to be stored about six pallets deep on carriers with slightly inclined rails. Pallets are loaded onto the rack via forklift, and as loads are removed, the following load moves down, which allows it to be picked from the rack face in sequence.
Pallets are placed on carts with wheels, which allows them to move to the picking position by gravity. When the front pallet is chosen, the following pallet moves forward.
Push Back Racks are installed against a wall for a single-sided system or on a center aisle for a double-sided system. When a new pallet is added, the cart will slide back and forth until capacity is reached.
