The objective of push back racking systems is to eliminate honeycombing or empty pick faces. Obviously, the ideal application for Push back Racks will be where all loads in a lane are identical and first-in/first-out stock rotation is not crucial.
How Push Back Racks work: Pallets are placed by forklift on nested carts riding on inclined rails. Each pallet is then pushed back by subsequent pallet loading, exposing the next cart. When removing product, the forklift takes out the front pallet, allowing the pallets on carts behind it to roll gently to the front of the rack. The nested carts make placement and retrieval easy.
