What are pulleys?

Pulleys are a type of lifting device. They come in different designs and sizes.

Pulley systems are used to lift heavy loads using mechanical advantage. They use a system of ropes, called a rope-way, which is supported by two or more pulleys. The system lifts the load by providing a mechanical advantage to the force applied on the rope-way. A pulley has an axle attached at one end and two or more wheels that rotate around it as it moves along its path of travel.
