Manual dumbwaiters are moved between floors by means of a hand-operated pulley system. Pulling the rope on one side will cause it to rise whilst pulling the opposite rope will cause it to descend. Although it may sound very labour intensive, the system of pulleys, counterweights, gears and brakes makes manual dumbwaiters much easier to use than. A dumbwaiter is a lift that is installed between the floors in a building. It is used to transport food, laundry or other items from one floor to another. Modern dumbwaiters are run by electric motors and are usually found in hotels, kitchens and restaurants. This manual lift science project uses pulley system.
