Freight lifts are goods conveyances specifically designed to transport goods in large quantities from one floor to another. Freight lifts generally have a larger and more powerful carrying capacity than people lifts, and are used to transport heavy goods such as machinery, industrial equipment and raw materials in factories, warehouses or distribution centers. Goods elevators usually use a hydraulic or electric motor drive system, and are equipped with pulleys, chains, or belts to transport goods. Freight lifts can also be made in various sizes and different carrying capacities, depending on the user's needs.
