Lifting chains are often used in conjunction with other types of lifting equipment, such as cranes, hoists, or winches. They are attached to the object that needs to be lifted using a hook or other type of fastener, and they are used to lift and move the object by pulling on the chain. The speed at which the object is lifted or moved can be controlled by adjusting the hand crank or lever on the lifting equipment, and the position of the object can be adjusted by moving the lifting chain to a different location.
