The pallet live storage of POLYPAL are compact structures, in a block, where roller paths with a slight inclination are incorporated that allows the sliding of the pallets on them.
They can be designed for FIFO operation (first in / first out, first palette to enter / first palette to exit) or LIFO (last in / first out, first to enter / last to exit). Both systems guarantee a fast and organized flow of the pallets, but each one has particular characteristics:
With the FIFO Dynamic racks, the pallets are loaded in the gravity channels on the input side and the slope causes the pallets to slide, at slow and controlled speed, from the loading point to the unloading point. When a pallet is unloaded, the next pallet occupies its space and is ready for its removal.
Space and busy volume are saved by requiring only one loading aisle and one unloading aisle. Conventional rack systems require additional aisles that this system does not need. The differentiation of loading and unloading aisles allows the design of safe picking areas with high performance.
The dynamic FIFO shelving from POLYPAL is the best solution for the storage of perishable products that require a perfect stock rotation.
In the LIFO Dynamic Racks, the loading and unloading are made by the front, with a single aisle, which allows optimal use of spaces on walls.
The pallets are loaded at different levels, from the same corridor for loading and unloading, until using all the depth of the rack. After placing the first pallet in the loading channel, the second pallet to position pushes the one already located, by the action of the forklift, until the total load of the rack. This requires that the first loaded pallet is the last one removed from the rack.
In this system, the number of references on the volume by reference is prioritized, using the same corridor for loading and unloading.
