A Push Back Racking System is operable with a LIFO storage system and considered the best solution for such companies with intense warehouse operations, that want to save on both fuel and the number of forklifts by means of using the racking vehicles (forklifts) in the shortest distances possible and, that want to make the best of the available warehouse area.
Push back pallet racks constitute a system that allows for the storage of more pallets compared to the other racking systems and, that increases the usage area of the warehouse by means of using the warehouse area in the most efficient manner. Increases the storage capacity by up to 90% compared to the standard racking systems. Significantly reduces the inefficient area that needs to be allocated for corridors in a standard warehouse on one hand, saves on time and fuel by means of considerably decreasing the movement distances of the stacking machines (forklifts) on the other hand.
The LIFO inventory method is that the foremost pallet in the corridors is picked up. On the sliding racks, loading is carried out on one side and, unloading is carried out on the other side. All the pallets are arranged on the same level except for the foremost pallets. The first pallet is loaded from the front, then pushed back to the second position when the second pallet is loaded. This procedure repeats until the entire rail throughout the tunnel depth on the rack has been loaded. Ideal for such warehouses with a high circulation and such areas where the storage cost is higher. Similar to a drive in racking system with the exception that the pallets are located on the rack from the front by means of a stacker (forklift) and then pushed back on the rails.
There are two different applications:
Roller System:
In this system, there are rollers that push back the pallets. Possible to use this system up to the depth of 9 pallets and, arranged in order using the 1200 mm portions of the depth.
Frame System:
Possible to use this system up to the depth of 6 pallets that are stored from the front in a way the parts of 1200 mm thereof are visible. Formed by means of stacking the products with a depth of 800 mm or 1000 mm. In this system, the pallets are stacked using telescopic rail frames instead of rollers.
Advantages:
- Allows for the storage of more pallets.
- Eliminates the need for corridors that are required for the stacking vehicles (forklifts) in a standard warehouse.
- Ensures that the available area and volume are efficiently used.
- Minimum loss of area in terms of rack heights thanks to the features offered by the system.
- One corridor is sufficient.
- Operates with the FIFO principle.
- Offers more efficiency in terms of movements in the warehouse.
- Shorter distances for the movements of stacking devices.
- Saves on the fuel of the stacking vehicles.
- Requires less number of stacking vehicles since the stacking vehicles are used in shorter distances.
- Ensures the operations are carried out in a faster manner.
- Unlike the other systems, there is no unused area on the rack during the unloading of the loads at any level.
- The pallets move without any energy consumption.
- Secure stacking and unloading operations.
