The principle of the hand chain hoist saving effort is mainly achieved through its internal gear and chain transmission system. By manually pulling the hand chain, the internal gears rotate, and the chain rises or falls along with the rotation of the gears, thereby achieving the purpose of lifting or pulling objects. Due to the adoption of multi-stage gear transmission, the hand chain hoist can generate a large lifting force with a relatively small force.
