A chain hoist is a mechanical device used to lift heavy loads by using a chain and a pulley system. It consists of a chain that wraps around a wheel, allowing users to pull the chain to raise or lower objects. Chain hoists are commonly used in construction, warehouses, and manufacturing settings for moving equipment and materials safely. These devices come in various sizes and weight capacities, making them suitable for different applications. Some chain hoists are operated manually, while others are powered by electricity. Safety features, such as overload protection, are often included to prevent accidents during lifting operations.
