Push-Back Pallet Storage Rack
Push-back pallet rack combines the density of drive-in rack with the selectivity of single-selective pallet rack. The uniqueness of push-back rack is the series of mobile carts that ride on rails within each row. A loaded pallet is placed on the upper cart within the system. As the next pallet is loaded, the forklift gently pushes the first pallet load back, exposing the 2nd cart. The process continues until all carts are used (typically 3-4 deep), with the last pallet resting on the rails. As each pallet is extracted the subsequent pallet flows to the aisle face for selection, allowing for highly productive pallet retrieval.
Push-back pallet rack is a last-in/first-out (LIFO) warehousing storage solution and is most often used for LIFO inventory rotation, but can be used for first-in/first-out (FIFO) depending on how the product comes in and out of the warehouse, as well as the depth of the system. For example, produce facilities with fast inventory turns use 2-4 deep push-back with FIFO rotation – all pallets are loaded to fill a push-back lane at the same time, then subsequently picked for shipment together as well. Additional vertical clearance is needed per level to accommodate stacked carts which may limit the number of vertical positions available. To learn more, see our video showing push-back in action.
Advantages | Considerations:
- High-density pallet storage system
- Requires limited number of aisles
- Ideal for high-volume, low-SKU applications
- LIFO stock rotation
- Minimized travel time for load and unloading
- Full SKU selectivity for every pallet position
