Push-back pallet racking system is an accumulative storage system that allows up to four pallets deep to be stored per level.

All the pallets of each level, except the top one, are placed on a set of trolleys that are pushed along rolling rails.

Push-back racking is a type of pallet storage system that allows pallets to be stored on both sides of an aisle, providing higher density storage than other rack systems.

A push-back rack system is a LIFO system, which is normally composed of an inclined rail section that extends the full depth of the storage lane.

Working of push-back pallet racks

With a push-back pallet racking system, a forklift will place the pallets on nested carts that move along inclined rails.

Each pallet is pushed back by the next pallet, which brings out the next cart. When the forklift removes products, it takes the front pallet first.

This enables the pallets on the carts behind the first pallet to roll toward the front of the rack.

The carts create an easy system for stocking and picking. The push-back system utilizes product rather than aisles to fill the storage space.

Main features of push- back pallet racks

They have linked carts, which helps to eliminate the possibility of a load being stranded and suddenly rolling out of control.

There are also serrated pallet grips that allow imperfect placement of pallets by grabbing the underside of the pallet ensuring that the load remains properly positioned on the cart.

They also provide a very low profile as the industry's lowest stack height can measure 6'' on a 6-deep pallet rack system.

The welded rail frame means the rails are permanently aligned at the factory to prevent field misalignment and costly maintenance.

Advantages of push- back pallet racks

The push-back rack offers more versatile storage because each lane flows independently and vertical storage operates separately from the underneath lanes.

They have such a provision that even the carts that are used in the system prevent jamming and damage to products.

Push-back pallet racks are especially useful if you have a SKU (individual products) stored on multiple pallets because you can store these pallets anywhere from two to six pallets deep.

These racks are utilized in high-density storage because they can store a lot of products while still enabling rotation of your products.
