Types of Sheave Pulleys

1. Fixed Pulleys

Fixed pulleys have a stationary axle and are used to redirect force and change the direction of a belt or cable.

2. Movable Pulleys

Movable pulleys have a movable axle and are used to increase mechanical advantage in lifting loads.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to provide increased lifting power.

4. Snatch Blocks

Snatch blocks are designed to be attached to a fixed point and redirect the direction of a rope or cable.

5. Idler Pulleys

Idler pulleys are used to maintain tension in a belt or cable system without changing the direction of force.

What is a sheave on a pulley?

1. Definition

A sheave is a wheel with a groove used to guide a rope or belt and change the direction of force.

2. Function

Sheaves help to increase mechanical advantage, reduce friction, and facilitate the movement of loads.

3. Components

A sheave typically consists of a wheel, groove, and axle to support the load and guide the rope or belt.

4. Types

Sheaves come in various sizes and designs to accommodate different applications and load capacities.

5. Importance

Sheaves play a crucial role in various industries such as construction, mining, and manufacturing by enabling efficient load movement.

What are sheaves used for?

1. Lifting Heavy Loads

Sheaves are commonly used in lifting systems to increase mechanical advantage and lift heavy loads with ease.

2. Reducing Friction

By guiding ropes or cables, sheaves help to reduce friction and improve the efficiency of mechanical systems.

3. Changing Direction

Sheaves are used to change the direction of force in pulley systems, allowing for versatile applications.

4. Maintaining Tension

Idler pulleys are used to maintain tension in belt systems, ensuring smooth operation and preventing slippage.

5. Power Transmission

Sheaves are essential components in power transmission systems, enabling the transfer of energy from one source to another.

6. Control Speed

Separate Inspection

Every sheave pulley is individually inspected to guarantee it meets the highest standards of quality and performance.


Each sheave pulley is marked with essential information such as load capacity and specifications for easy identification.

How do you adjust sheave pulleys?

1. Tension Adjustment

By adjusting the tension of the belt or cable connected to the sheave pulley, you can control the speed and movement.

2. Size Adjustment

Changing the size of the sheave pulley can alter the mechanical advantage and power transmission in the system.

3. Lubrication

Regular lubrication of the sheave pulley components can help to reduce friction and ensure smooth operation.

4. Alignment

Proper alignment of the sheave pulleys with the belt or cable is essential for optimal performance and longevity.

5. Inspection

Periodic inspection of the sheave pulley system can help identify any issues early and prevent costly repairs down the line.

6. Consultation

If unsure about how to adjust sheave pulleys, it is recommended to consult the manufacturer’s guidelines or seek professional assistance.
