Principle of aluminum alloy hand chain hoist

The hand chain hoist is an upgraded version of the pulley. It completely inherits the advantages of the pulley. The hand chain saves effort by using the principle of mechanics to drive the hand chain by manpower to generate traction, and by using the gear transmission method, the small gear drives the big gear, which transmits the magnified torque, so as to drive the lifting chain to complete the lifting of the heavy objects.
