Push back racking is a type of high-density storage system used in warehouses and distribution centers to maximize storage capacity and improve efficiency. It is designed for storing palletized goods and utilizes a dynamic “last in, first out” (LIFO) storage principle.

In a push back racking system, the pallets are loaded onto a series of nested carts or trays that are mounted on inclined rails. When a new pallet is loaded into the system, it pushes the previously loaded pallets back along the inclined rails, hence the name “push back.” This allows for multiple pallets to be stored in a single lane, with each pallet positioned behind the previous one.

The system relies on gravity to move the pallets along the rails, eliminating the need for additional power sources or equipment. When a pallet is retrieved from the system, the remaining pallets move forward, making the next pallet easily accessible at the front of the rack.

Push back racking offers several advantages. It provides excellent space utilization since it maximizes the use of vertical space and eliminates the need for multiple aisles. It also offers selectivity, allowing access to a range of products stored within a single lane. Additionally, the system is relatively easy to operate and can accommodate a variety of pallet sizes and weights.

However, it’s important to note that push back racking may not be suitable for all types of products. It is best suited for high-density storage of homogeneous goods with a large number of pallets per SKUs. Additionally, because this system operates on castors/wheels, it requires proper maintenance to ensure smooth operation and safety.
