What is a manual crane hoist?

A manual crane hoist, also known as a manual chain hoist, is a type of lifting equipment that is operated by hand. It consists of a chain or wire rope that is wound around a drum, and a set of gears and pulleys that are used to increase the lifting force. The operator pulls on a chain or lever to lift the load, and the weight is held in place by a braking system. Manual crane hoists are typically used in areas where there is no power source or where access is restricted, such as in small workshops or construction sites. They are commonly used for lifting and moving materials such as steel beams, heavy machinery, and construction materials. Manual crane hoists come in a variety of sizes and capacities, and they are designed to be portable and easy to use. However, they require a certain amount of physical effort to operate, and they may not be suitable for lifting extremely heavy loads.
