A cumulative storage system that allows storage of up to four pallets depth per level. All pallets on each level are placed on a set of carts that are pushed along the support rails.

The backward motion is ideal for storing mid-rotation products, with two or more pallets at storage level using the Last In First Out (LIFO) system.

Its name comes from the fact that the pallets push the stored material, moving it to the bottom and when it is removed, the material is positioned at the beginning.

Advantages
• The forklift has access to the material as if it were a selective rack.
• Similar materials can be stored.
• Easy inventory control.

Applications
• Non-perishable products.
• Refrigeration or freezing chambers.
• Distribution centers.
