Types of Wheel Pulleys

Fixed Pulleys

Fixed pulleys have a stationary wheel and are commonly used in lifting applications where the direction of force needs to be changed.

Movable Pulleys

Movable pulleys have a wheel that moves along with the load, providing a mechanical advantage and making it easier to lift heavy objects.

Compound Pulleys

Compound pulleys combine fixed and movable pulleys to increase the lifting capacity and make lifting heavy loads more manageable.

Examples of Usage

  • Fixed pulleys are preferred in flagpoles to change the direction of the force.
  • Movable pulleys are used in elevators to lift and lower the elevator car.
  • Compound pulleys are commonly found in construction cranes for lifting heavy materials.

Advantages of Using Wheel Pulleys

Increased Mechanical Advantage

Wheel pulleys provide a mechanical advantage, making it easier to lift heavy loads with less effort.

Energy Efficiency

Using wheel pulleys can help save energy as less force is required to move heavy objects.


Wheel pulleys are cost-effective as they reduce the amount of manual labor needed to lift heavy loads.

Maintenance and Troubleshooting
