Pallet Live Storage (PLS), also known as Pallet Flow Racking, is a high-density storage system that uses gravity to move pallets forward on inclined roller tracks. This system follows the First-In, First-Out (FIFO) principle, making it ideal for industries that require efficient stock rotation, such as food, beverages, and pharmaceuticals. PLS maximises storage space by allowing multiple pallets to be stored in deep lanes, reducing the need for multiple aisles. It improves warehouse efficiency, reduces handling time, and lowers operating costs by eliminating the need for powered systems, making it a practical solution for high-volume, time-sensitive storage needs.
