Types of Wheel Pulleys

Fixed Pulleys

Fixed pulleys do not move and are often used in simple lifting systems.

Movable Pulleys

Movable pulleys can move along the rope or cable and are commonly found in more complex lifting systems.

Compound Pulleys

Compound pulleys combine fixed and movable pulleys to provide increased mechanical advantage.

Examples of Usage
