Types of Sheave Pulleys

1. Fixed Pulleys

Fixed pulleys have a stationary axle and are used to redirect the force in a lifting system.

2. Movable Pulleys

Movable pulleys have a free rotating axle and are commonly used to increase mechanical advantage in lifting operations.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to provide a greater mechanical advantage.

4. Snatch Blocks

Snatch blocks are versatile pulley systems that can be attached to various anchor points for different pulling directions.

5. Wire Rope Pulleys

Wire rope pulleys are specifically designed for use with wire rope to lift heavy loads.

6. Timing Belt Pulleys

Timing belt pulleys are used in timing belt systems to transfer rotational motion efficiently.
