Chain hoist cranes are machines used to raise and lower heavy objects using chains and amplifying force by leverage and pulley. These machines actually use gears instead of pulleys, and spur gears are mainly used. Internal gears have functions to amplify force and change hoisting and lowering speeds. Chain hoist cranes are also equipped with a braking system so that cargos will not fall even when you take your hands off the chains. Cranes refer to machines designed to hoist cargos and transport them laterally using motive power, excluding mobile cranes and derricks. By combining gantry cranes, overhead cranes and similar types of crane with a chain hoist, it is possible to hoist heavy objects and move them laterally.
