Push back racking system fills the storage cube with product, not aisles. Instead of single Pallet-deep selective racks, a Push Back Racking system lets you store pallets 2 to 5 deep while retaining easy access to a variety of different SKUs.
1, High densities - three and four deep systems are common, which allows blocks of 6 or 8 deep, with back to back rows. Depths of up to 6 deep are also available, at higher costs.
2, improved selectivity over Drive-In, which Push-Back often replaces.
3, Efficiency vs. Drive-In - trucks do not need to drive into rack loads come to them at the pick face.
4, Applicable for goods of "Small variety big quantity", and operation method of "First in, last out". Also applicable for condition of bigger spacer utilization ratio.
Advantages:
In a typical three deep, back to back Push Back system, space savings would amount to around 40% vs. Single Selective Rack.
Converting an existing space from Single Selective to Push Back would accommodate an increase of about 60% in pallets stored.
How push back rack works:
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.
