Push-back racking is a high-density storage system, allowing up to six pallets deep storage on either side of an aisle.
Push-back racking works with at least three nested mobile carts, gliding on sloped rails to hold and carry pallets. The first pallet, loaded from the front, sits on the top cart. When the second pallet is loaded onto the cart, it pushes the top cart with the first pallet back.
It operates like a soft drink cooler in a convenience store, where when you pull a bottle out, a new one slides forward.
The pallet 'push-back' mechanism makes pushback racking ideal for operations using the Last-In, First-Out (LIFO) inventory method.
Push-back racking can achieve higher density storage – up to 75% more than selective racking – while allowing more selectivity with storage. But you can only store the same SKU in a single lane.
