Types of Wheel Pulleys

Fixed Pulleys

Fixed pulleys are stationary and change the direction of the force applied to the load. They are commonly used in flagpoles.

Movable Pulleys

Movable pulleys have a sheave that moves with the load, reducing the effort required to lift the load. They are often used in elevators.

Compound Pulleys

Compound pulleys combine fixed and movable pulleys to provide both a mechanical advantage and the ability to change the direction of the force. They are ideal for heavy lifting applications such as construction cranes.

Advantages of Using Wheel Pulleys

  • Increased mechanical advantage
  • Ability to move heavy loads with less effort
  • Energy efficiency
  • Cost-effectiveness

Maintenance and Troubleshooting

Regular Maintenance

Regularly lubricate the wheel pulleys to ensure smooth operation. Inspect for any signs of wear and tear.
