Push-Back Rack
Push back rack is a type of high density pallet storage rack for Last-In-First Out (LIFO) inventory storage. Multiple factors should be considered before selecting this storage type, including product inventory, shelf life, product accessibility, forklift type, and others.
How A Push-Back Pallet Rack Works
Push-back storage systems consist of a pallet rack structure supporting gravity flow lanes that are pitched from back-to-front. The flow lanes are made up of parallel rails that support a series of carts to support the pallets stored in the system. When the lanes are empty, the carts flow forward and nest over each other in the front load position until new pallets are added to the lane. As pallets are added to a lane, the loaded pallet pushes back the pallets already in the lane until the lane is full. Pallets are picked from a lane at the same place they are added and all pallets flow forward by gravity until the last pallet in the lane is in the front position. Pallet flow rack typically allows pallet storage from 2 deep up to 6 deep per lane of storage.

Common Questions Regarding Push-Back Rack
The biggest advantages of push-back pallet rack are the ability to offer both selectivity (access to different pallets/SKU’s) and storage density by storing multiple pallets per location.
Customized push-back pallet rack systems are indeed available, making an already custom-engineered system even more individualized to unique applications. Push-back systems can be engineered to accommodate special pallets, such as extra-long and extra-wide pallets, as well as pallets that are not strong enough to support themselves. In the latter situation, push-back carts are outfitted with additional reinforcement and wire mesh to create additional structure for support.
