Product Introduction:

Push back racking is evolved from pallet racking , it is a form of high-density storage.As a pallet is loaded from the front, it pushes the pallet behind it back one position. The front pallet is removed when unloading and the rear pallets automatically come forward to the front picking position.

This kind of rack offers more versatile storage than Drive-In rack because each lane flows independently and vertical storage operates separately from lanes below. Multiple pick facings for a variety of SKUs can be stored and retrieved without disturbing other product above or below in a single-lane or double-lane format.


Advantages:

1. Push Back Rack is designed to increase storage efficient, its concept is stackable carts move from the front to the back beam on special inclined rails.

2. First store-in pallet sit on the top cart, the second store-in pallet push the top cart to the back and vacant the second cart for the second pallet.

3. While picking up the front pallet from the rack, the second pallet will silde to the front.

4. It is a first in and last out storage concept but it is different from Drive-in rack, handling truck operate only at the front of the rack without drive into the rack.

5. Saves maintenance time and repair costs because you are not driving into the rack;

6. Allows for high-density storage of multiple SKUs;

7. Big space saver due to minimized need for aisles;

8. Fast operation.
