2. Movable Sheave Pulleys

Movable sheave pulleys have a wheel that can move along the axle to adjust tension.

3. Compound Sheave Pulleys

Compound sheave pulleys have multiple wheels on the same axle to increase mechanical advantage.

4. Snatch Sheave Pulleys

Snatch sheave pulleys are designed for quick and easy attachment to ropes or cables.

5. Tandem Sheave Pulleys

Tandem sheave pulleys have two wheels side by side to distribute load evenly.

6. Synchronous Sheave Pulleys

Synchronous sheave pulleys are designed to work together with timing belts for precise motion control.

What is a Sheave on a Pulley

• A sheave is a wheel with a groove used in conjunction with ropes or cables to change the direction of a force.
• It helps to reduce friction and increase efficiency in lifting or pulling operations.
• Sheaves are commonly found in pulley systems to transmit power or motion.
• They come in various sizes and materials depending on the application.



• Sheaves are essential components in mechanical systems for transferring force.

What are Sheaves Used For?

• Sheaves are used to change the direction of a force in lifting or pulling applications.
• They help to increase mechanical advantage and reduce the effort needed for lifting heavy loads.
• Sheaves are crucial in pulley systems for transmitting power efficiently.
• They are commonly used in industries such as construction, mining, and transportation.

Process of Sheave Pulley

Our sheave pulleys undergo a meticulous production process to ensure top quality:

1. Mold: Design and create the mold for the sheave pulley.
2. Casting: Pour molten metal into the mold to form the sheave pulley shape.
3. Raw materials: Use high-grade materials for durability and performance.
4. Production: Manufacture the sheave pulley with precision and attention to detail.
5. Testing: Conduct rigorous testing to ensure the sheave pulley meets quality standards.
6. Antirust treatment: Apply a protective coating to prevent corrosion and increase longevity.
7. Separate inspection: Inspect each sheave pulley individually to guarantee quality.
8. Marking: Label the sheave pulley with necessary information for identification.

How do you adjust sheave pulleys?

• Adjust the tension by moving the movable sheave along the axle.
• Use a wrench to tighten or loosen the sheave pulley as needed.
• Ensure proper alignment of the sheave pulleys for smooth operation.
• Check for any wear or damage on the sheave pulley components.
• Consult the manufacturer’s guidelines for specific adjustment instructions.
• Regularly inspect and maintain sheave pulleys to prevent issues.
• Seek professional help if you encounter difficulties in adjusting sheave pulleys.
