Types of Sheave Pulleys

1. Fixed Pulleys

Fixed pulleys are stationary and change the direction of the tension force on the cable or belt that runs around it.

2. Movable Pulleys

Movable pulleys are attached to the object being moved, and as the object moves, the pulley moves as well to provide mechanical advantage.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to increase the mechanical advantage for lifting heavy loads.

4. Snatch Blocks

Snatch blocks are versatile pulleys that can be attached to different anchor points to change the direction of the tension force.

5. Wire Rope Pulleys

Wire rope pulleys are specifically designed to work with wire ropes for lifting and pulling applications.

6. Nylon Pulleys

Nylon pulleys are lightweight and corrosion-resistant, making them ideal for various applications where weight and environmental conditions are a concern.
