Chain Hoist Machine

A chain hoist is a mechanism that exerts a force for lifting or lowering an object by utilizing a drum or lift wheel around which rope or chain wraps. Friction brakes help hold the load or object and can be used to help control the descent of the load.A chain hoist is a mechanical device used for lifting heavy loads of objects and equipment. It is made with a pulley, which is held together by a closed chain. The closed chain forms a loop, which makes it easy to be pulled by hand. There are several large and small pulleys located throughout a chain hoist.The three-phase induction motor with electromagnetic brake is commonly used for electric hoist. The working principle of three-phase induction motor is based on electromagnetic induction.
