What is Push Back Rack?
Push Back Pallet Rack utilizes wheels in the rack structure. This type of pallet rack system allows palletized goods and materials to be stored by being pushed up a gently graded ramp. Stored materials are allowed to flow down the ramp to the aisle. This rack configuration allows for deep storage at each rack level and last-in, first-out (LIFO) storage.In push back, rack systems pallets are placed on rolling carts, which slide from the front of the rack to the rear of the rack. As new pallets are loaded into the rack from the aisle side of the rack system, exiting pallets are pushed to the rear to make space. Push back racks utilize standard forklifts and provide a cost-effective alternative when last-in, first-out (LIFO) inventory rotation is used. Pallets are typically stored two to six pallets deep providing more storage space with fewer aisles than conventional selective pallet rack. Push back racks allow greater selectivity than drive-in racks while providing excellent utilization of storage positions.
As budgets remain tight, proper space utilization becomes a must for all warehouses. Push back pallet rack increases the amount of pallets that can be stored and also offers more pick faces than typical high-density systems. When an average number of pallets per part or product exceeds five in quantity, push back systems become more justified. Push back pallet rack can offer 100% more storage than standard selective pallet rack and can also offer a solution to the honeycomb effect of standard high-density drive-in pallet storage systems.

10 Things to Know about Push-Back Pallet Rack:
- Compared to standard selective pallet rack many forklift operators think push back pallet rack is easier to load and unload.
- Rack damage is minimized because lift trucks never enter the rack system.
- Push back aisles usually only need to be 6″ larger than your manufacturers’ minimum aisle requirement.
- Push back is a low-maintenance pallet storage rack system.
- Most standard forklifts can be used with a push back rack system.
- Standard push back systems are designed to hold a max pallet weight of 3000 lbs but can be designed for heavy load ratings.
- Standard GMA pallets are most commonly used in push back systems although systems can be designed to hold other styles and size pallets.
- Push-back will require more height per level than selective rack- typically 6-8″
- Hybrid systems are commonly used (i.e drive-in on floor level- push-back on the upper levels
- Structural Rack is preferred and often required for push-back systems.
