What Is Push Back Racking?
Push back racking (often called pushback rack) is a high density pallet storage system that allows pallets to be stored from 2 to 6 units deep. Pallets ride on nested shuttles that are pushed up a gradual slope as products are loaded, or “pushed back” from the front of the racking system.
When products are later unloaded, the pallet immediately behind the front pallet glides back down the gradient to the facing position.
Push Back Rack Advantages And Disadvantages
Pushback racking is perfect for some operations, but is not a fit for every warehouse. Here are some of the favorable and possibly unfavorable aspects to investigate.
Higher Density Storage
Because push back pallet racks can accommodate anywhere from 2-6 pallets in any given lane, they can eliminate somewhere from 1-5 aisles, which can be a significant chunk of warehouse space.
Less Forklift Travel
With a reduction in aisle number, lift trucks don’t have to rack up as many hours, reducing equipment wear and increasing efficiency. Lower lift truck movement also greatly increases safety inside the warehouse. Less travel means a lower number of collisions.
Pushback rack gives warehouse managers an ideal blend of product selectivity and storage density. Different from drive-in rack, where entire storage bays are generally one SKU, push back features straightforward access to a much greater number of pallet positions from the aisle.
Dissimilar to pallet flow rack, which is a First In First Out (FIFO) type of system, push back rack is a Last In First Out (LIFO) type of plan. This means that it’s not generally suitable for goods that are perishable, because products that are added early will often sit for quite a long period of time as products are added and depleted from the rack face.
How Does Push Back Racking Work?
Push back racks utilize a couple of rails sloping in the direction of the aisle and a set of nested shuttles which ride on these rails.
An initial pallet is placed on the highest cart by a forklift. When a new pallet is positioned, the forklift operator forces the first pallet back and positions the next pallet on the second cart. The last pallet placed in the lane sits on the rails.
In the unloading process, shuttles loaded with pallets slide down the rails. Workers remove each pallet in succession until the lane is empty, or supplement additional pallets, refilling the lane.
