Push back racking is one of the storage racks with the highest storage utilization rate, mainly composed of columns, beams, rails and wheeled carts. The track tilts slightly to the side of the access goods. When storing goods, the goods in front of a pallet are pushed to the designated position by the forklift. When picking up goods, affected by gravity, the carts will carry the goods on the pallet slowly rolling to pick up goods, which saves labor costs and time. Generally, a maximum of 6 pallets are designed for each set of cargo space, which can be accessed from both sides of the cargo space. Push-back rack is a LIFO storage system.

The push back rack is also called press-in rack. It is a combination of track and pallet trolley principle, the track is about 3% slope, using the self-weight of the goods, in order to achieve the purpose of goods in and out of storage. Push back racking system is connected by overlapping multi-layer carts between the front and rear beams, and the pallets are placed into the carts from the outside, and the goods will push the original goods inside. The trolley is placed on an inclined track so that when the outside goods are taken away, the inside goods will automatically slide down. Push back pallet rack system has large storage capacity, high space utilization, suitable for small variety and large volume of goods, first-in, last-out(FILO) operation method, incoming and outgoing goods on the same side.

Push back racks are suitable for the storage of fewer varieties and more batches of goods. The installation of push-back racks is relatively simple. Special attention should be paid to the installation of guide rails. The guide rails need to calculate the inclination of the track according to the weight of each pallet of goods. Reasonable design can ensure the safe and smooth operation of the cart when loading and unloading goods.
Punches run the length of the hanging plate at standard intervals where the cross beams are connected, most of them are 50mm or 75mm pitch.
Steel coil through the rolling equipment to form the upright and beam, beam usually have P beam and interlock beam, upright usually have diamond hole and teardrop hole.
Through welding, the hanging plate and beam; upright and footplate are closely connected together, which effectively strengthens the stability of the rack structure.
Polish the product after welding, then use electrostatic powder spraying technology on the surface, and finally use the high-temperature baking process to ensure a smooth surface.
Finally came to the last step. After the production of the product is completed, we usually package the exported goods to avoid long-distance transportation damage and seawater erosion during shipping.
1. When the quantity of pallets for a product is large and “first in, first out” is not required, push back rack simplifies the work process and provides significant benefits.
2. Shortening picking time and eliminating the need for special material handling equipment.
3. High space utilization and productivity due to more storage areas and fewer aisles.
4. Push back pallet racking can avoid the cargo damage that often occurs during loading and unloading operations in high-density storage racks.
Compared with ordinary racking, push back pallet racking can increase the utilization rate of the ground by about 60%. Push back racking system is safer and more efficient, and can be used only with a forklift or counterbalanced forklift, and requires less forklift operation than drive-in racking.
The total depth of push back racking should not be too deep, generally within 6 pallets depth. If more than 6 pallets, there will be less storage space because the pallet trolleys are embedded in each other, and the majority of users choose 3-4 pallets deep push back pallet racking.
The top layer cargo of push back racks can exceed the rack upright. Since the top of the push back racking does not need to be fixed by a support bar, when used push back racking storing goods on the racks, even if the uppermost goods exceed the height of the rack uprights, there will be no adverse effects on the racks as long as there are no obstacles in the space above the racks.
Push back racks are heavy duty warehouse racks, so when push back pallet rack manufacturers are installed, all need to be fixed to the ground using anchoring. If the ground is a little uneven, you can use shims to pad it to the same height, so that the installation is stable. If there are many places in the warehouse that are uneven and seriously affect the installation of push back rack, then you need to solve this problem before installation.
When planning the warehouse, you can ask the push back pallet rack manufacturer to appropriately increase the width of the incoming rack aisle and reserve a certain safety distance for forklift drivers in advance to reduce the impact of forklifts on the racks. Then equip the uprights of push rack system with upright protectors or crash barriers, which can also reduce the damage of forklifts to the racks.
The design of the push back racking scheme needs to be determined according to the pallet size, pallet loading capacity, and the max weight of goods to be stored in each pallet position, etc. Also, the design of the push back racking system scheme needs to fully consider the warehouse size, height, fire hydrant location and entrance/exit location, etc. Finally, the design of the push back pallet racking scheme also takes into account the comprehensive data of the forklift, the max lift height, the max weighing weight, the width of the forklift, etc. Before installation, there will be on-site construction drawings for reference, and for some difficult installation projects will also arrange for professional staff to guide on-site and adjust the construction drawings appropriately according to the installation situation.
Gravity rack adopts roller type track or bottom wheel type pallet, the track is about 3° slope, using the self-weight of the goods to achieve the “first-in-first-out” of the goods, one side in and one side out, suitable for large quantities, similar goods storage operations, high space utilization, especially for goods with a certain shelf life, not suitable for long-term backlog.
Push back rack adopts track and pallet trolley, the track is about 3° slope, using the self-weight of the goods to achieve the “first-in-last-out” of the pallet goods, the same side into the same side out, applicable to the storage of large quantities of less variety of goods, high space utilization, access is also more flexible and convenient.
Push back racking is a first-in-last-out model that uses rails and pallet trolleys with a 3% or so slope, and push back racking cost range from $150 to $500 per pallet.
First of all, relative to the shuttle rack, the depth of the push back racking system can not be too long, generally within 6 pallets. Secondly, the installation of the push back racking is more complex, and the guide rail needs to be tilted at an angle of about 3 degrees. The installation accuracy of push back racking system is required to be high, otherwise, it will affect the normal operation of the track car.
