A chain hoist is a mechanical device used to lift heavy loads vertically. It consists of a chain, a hook, and a lifting mechanism that can be operated manually or electrically. Chain hoists are commonly used in construction, warehouses, and manufacturing to move items safely and efficiently. These devices come in various capacities and designs, making them suitable for different applications. The chain is looped around a wheel, allowing the user to pull on one end to lift the load. Safety features, such as overload protection, are often included to prevent accidents during operation.
