A pulley is a simple machine that can be used to increase the lifting force using a sprocket and string, rope, or chain. These useful devices are widely used in modern machines. You can find numerous examples of pulleys in your community. Look for popular pulley-based systems the next time you go shopping, walking, or visiting a local school or theater.

Elevators

Elevators work via a powerful electronic pulley system. Indeed, elevators use a system of multiple pulleys and counterweights to provide both strength and safety to the elevator system. Some building planners like to create blueprints that allow you to see the elevator's internal machinery. When looking down a visible elevator shaft, look for the thick steel cables that slide through the drums and pulley systems to raise the platform box.

Wells

Old-fashioned "wishing well" -style fountains are often equipped with a simple pulley system to aid in pulling water (not to be confused with crank systems that wrap the rope attached to a bucket around an axis). Well discs consist of a mounted wheel onto which a rope or chain with a bucket attached to one or both ends is screwed. The pulley makes it easier for the user to pull the bucket up than it would otherwise.

Exercise equipment

Most strength training machines use pulleys to control the angle at which weights are lifted while keeping the weights themselves in a specific location. This makes the weightlifting process safer and more effective for the user than free weights if used improperly.

Construction panels

Construction pulleys are some of the most basic and widely used pulleys used to indicate the basic functions of this simple machine. These pulleys consist of a wheel track that can be lifted to great heights and is fitted with chains or ropes attached to hooks. These pulleys allow workers to raise or lower equipment on construction sites so they don't have to climb up and down to get the tools or materials they need.

Theater systems

In theaters, curtains and fly systems work with a system of multiple pulleys. Located high above the stage where the audience cannot see them, these pulleys are operated from the side of the stage to raise and lower curtains and sets during a theatrical performance.
