Characteristic of first-in-last-out(FILO) racks

- Feb 12, 2020-

Pallets are stored in depth direction with high storage density and high utilization rate of warehouse.

FIFO and FILO can be achieved, but forklift must be driven into the rack aisle for operation.

It can be set as unilateral access or bilateral access.


Generally, it is better to control the depth of 7 cargo spaces on one side and 12 cargo spaces on two sides in order to improve the efficiency and reliability of forklift’s access.

The operation speed of forklift can be improved by configuring the guiding rail.

The rack height should be controlled within 10 m, and the pulling device should be added at the same time.

Single pallet shouldn't be overloaded, usually controlled within 1.5T, pallet size should not be greater than 1.5m, usually equipped with forward forklift or balanced weight forklift.


Characteristic of push back rack

The goods stored in the push back rack are stored on the specially manufactured pallet trolley. The pallet trolley realizes the self-slipping function through the guide rail with a certain slope. When storing the goods, the forklift is used to store the goods from the lower end of the guide rail on the pallet trolley, and then the forklift pushes the former pallet into a deep position with the next pallet, and so on.

Goods are also taken from the lower end of the guide rail. Every cargo is taken away, the remaining cargo will automatically slide to the lower end of the guide rail under the action of gravity, so that it is convenient to continue to pick up cargo for the FILO rack.


There are many factors to be considered in the planning of the push backrack system. It is necessary to design and plan according to the current domestic and foreign technical specifications for reference. It is necessary to optimize the design and planning not only from the structure, but also from the structure, design and selection of components. Through certain simplified theoretical calculation and computer simulation planning, accurate manufacturing and assembly accuracy can be achieved. Standardized installation, construction and commissioning, together with later warehousing management, maintenance and operation, can ensure the safe and efficient application of the push backrack system.
