Stacking loaded pallets saves space in trucks and warehouses and thus contributes to a higher load factor and higher storage capacity. In addition, stacked pallets provide extra efficiency, as a forklift operator can move two or perhaps even three pallets at a time. The only condition is that the pallets must first be placed on top of each other, for which forklift trucks or manual stackers are usually used. This work requires not only extra time, but also the necessary precision to prevent product damage.
