How do air hoists work?

Air-hoists function using air pressure to provide the force necessary to lift a load. While electric hoists depend on the power of an electric motor to move the load from one place to another, air hoists use differentiating air pressure to produce enough lift to move heavy objects.

How does a hoist work?
