Depending on the environment and operational requirements, pallet lifts may incorporate a mast or scissor lift mechanism. Both provide a substantial and stable load surface to accommodate pallets, most frequently offering load capacities of up to 2000kg. Pallet lifts are designed to be versatile and totally safe when raising and lowering goods to optimum working, loading and transfer heights. Precise control is commonly achieved using simple push buttons although the lifts may be incorporated into fully automated handling systems. Many pallet lifts are available with a low profile closed height of 80mm, or even less, which means that they can be loaded and unloaded by means of a low ramp which eliminates the requirement for a pit to be recessed into the flooring.
