Types of Sheave Pulleys

1. Fixed Pulleys:

Fixed pulleys are attached to a stationary object and change the direction of the force applied to the rope or cable.

2. Movable Pulleys:

Movable pulleys are attached to the object being moved and provide mechanical advantage by reducing the amount of force needed to lift the object.

3. Compound Pulleys:

Compound pulleys combine fixed and movable pulleys to create a system that offers both a mechanical advantage and changes the direction of the force.

4. Block and Tackle Pulleys:

Block and tackle pulleys consist of multiple pulleys working together to provide a greater mechanical advantage for lifting heavy loads.

5. Snatch Blocks:

Snatch blocks are designed to be easily attached to a rope or cable to change the direction of the force and increase the pulling power.

6. Wire Rope Pulleys:

Wire rope pulleys are specifically designed to work with wire ropes and cables, providing a smooth and efficient operation.
