Push back storage rack offers similar storage density as drive-in pallet rack while improving selectivity and accessibility to a range of SKUs. Product stored in lanes rests on a system of carts-on-rails available in 2 to 4 pallets deep. From one aisle, pallets are stored by pushing back previously placed pallets with a new pallet on the next cart position. When the front pallet is retrieved, gravity causes the next pallet to move forward into a ready position. This "last-in, first-out" system reduces picking time when a large number of picking faces are required.
Push back storage rack is a system where there are rollers on the racking that allows the fork lift truck to push back the pallets to allow one pallet to be stored in the front of another. The Material box or pallets are put on the trolley from outside, the subsequent material box or pallets will push the prior back up a channel rail. The Roller Rail is inclined track .When the outboard material box or pallet is taken away, then the inside one will slide down automatically and take into position.
Welfor patented design features large coated wheels with sealed bearings. The linked cart design provides smooth operation in the pallet rack system. Push back storage rack provides a very desirable combination of high density storage and pallet accessibility. Welfor storage density equals that of drive-in pallet rack systems, yet every lane can be accessed at all times. Any lane can be filled from the aisle without affecting any other adjacent lanes above or below.
●A medium cost storage solution providing high-density storage.
●Quick easy access to all lines.
●Maximum use of floor space.
●Pallets are stored 2, 3, and 4 deep.
●Suitable for bulk storage/ cold room store applications.
How the push back trolley operated
The Push Back Racking System features a nested cart system that holds up to 6 trays per pallet location. The pallets are located at the top of these trolleys, and when the pallets are loaded, the pallets on the pick side are pushed back, as well as any pallets behind. Then place the new pallet on the trolley nested below. When the pallet is pulled out of the picking surface, so the pallet behind moves forward one position.
