Push Back Rack Systems

Push Back Rack offers exceptional space utilization by storing pallets 
two to five deep while allowing for high selectivity



Push Back is an accumulative, high density storage system that allows multiple-product storage conformations. These systems are available in two, three, four or five deep pallet configurations and offer optimization of the storage area while combining excellent selectivity and a maintenance-free design.


The pallets are placed on a free-rolling carriage that is pushed back into the system by loading additional pallets. Gravity moves the pallets forward to the aisle on the telescoping carriages, eliminating the need to reach or drive into the rack.


The pallets are arranged in a Last In First Out (or LIFO) system where the last pallet stored is the first one to come out. This system minimizes space requirements and maximizes the number of picking faces.


Push back rack systems operate very simply:

1. Each rack level is equipped with one, two or three sets of parallel carts at different heights.

2. The forklift places the first pallet on the highest set of parallel carts.

3. When loading the second pallet, the forklift pushes the first pallet until it reaches the next set of carts and places the pallet on them.

4. If the facility is designed for storing four pallets, this operation is repeated with the third pallet and the last pallet rests directly on the rolling tracks, and not on the carts.

5. The operation is reversed when unloading pallets. When the first pallet is removed, the others move forward one place toward the aisle.


The system can be adapted to store two, three or four pallets in depth. After the pallet model and measurements, the available space, and the type of forklift to be used have been analyzed, the number of pallet depths assigned for storage can be determined. The construction system is similar in all of these cases; the only varying difference is the number and measurements of the carts and rails.
