Types of Wheel Pulleys

Fixed Pulleys

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

Movable Pulleys

Movable pulleys have a pulley that moves with the load, providing a mechanical advantage. They are commonly used in elevators or cranes.

Compound Pulleys

Compound pulleys combine fixed and movable pulleys to increase the mechanical advantage. They are ideal for lifting heavy loads with minimal effort, such as in construction sites.

Advantages of Using Wheel Pulleys

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

Maintenance and Troubleshooting
