Push back rack is evolved from the pallet rack, also known as push back shelves or press-in shelves.The principle of Push back rack is the combination of rail and pallet trolley, the rail is a certain slope (about 3 degrees), pallet goods stored in the shelf according to their own weight.
The cargo access of push back rack is fist-in-fist-out, suitable for large quantities of less variety of goods storage when need a high utilization of space and a more flexible and convenient access.
The total depth of the shelf is not recommended too deep, generally within 6 pallets depth is ok. Because the pallets car is embedded into each other's sake, this will make space sacrifice. Also the single care goods is generally within 1500kg weight and the shelf height is below 6m.
This type of system has high requirements for the manufacturing precision of the racking. The cooperation between the pallet trolley and the guide rail is especially important. For example: if the manufacturing and installation precision is not good, it will make the racking system run poorly easily.
The cost of push back rack is pretty, push back rack is very suitable for the cold storage or storage area is limited but need to increase the storage area of the occasion.
1. The pallet truck has the characteristics of flow, the goods are provided at one end of the shelves, follow the Fist-in-fist out order.
2. When storage and transportation of goods, the forklift truck is only operate at the lower end of the shelf channel, no need to enter the shelf. Push back rack have the typical features like high storage density, high storage and transportation speed.
3. Usually applicated in the extremely limited storage area, but must increase the storage capacity occasions.
