Telescopic forks can be extended to transport two pallets at a time if necessary. This can generate considerable benefits involving large volumes or long distances. When compared to a double pallet clamp, the weight of the telescopic forks is much lower and visibility is much better, thereby enhancing safety. Another possibility is to load or unload two pallets at a time from wagons or trains. Combinations with a fork positioner and spreader are possible as well, allowing to handle 4 pallets at a time which improves the loading and unloading speed of trucks and trains enormously.
