Types of Sheave Pulleys

1. Fixed Pulleys

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

2. Movable Pulleys

Movable pulleys have a pulley attached to a moving block and are used to provide a mechanical advantage.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to provide an increased mechanical advantage.

4. Block and Tackle Pulleys

Block and tackle pulleys consist of multiple pulleys arranged in a block and tackle system for lifting heavy loads.

5. Snatch Blocks

Snatch blocks are specifically designed for use with wire ropes to change the direction of pull.

6. Wire Rope Pulleys

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

What is a sheave on a pulley?

  • A sheave is a wheel with a groove used with a belt or rope to change the direction of a force
  • It helps reduce friction and distribute the load evenly
  • Sheaves are commonly used in pulley systems for lifting and rigging
  • They come in various sizes and materials depending on the application
  • Sheaves can be used in different configurations to achieve specific mechanical advantages

The mold for sheave pulleys is carefully designed to ensure precision and consistency in production.


The raw materials are melted and poured into the mold to create the desired shape of the sheave pulley.

Raw Materials

High-quality materials such as steel or aluminum are used to ensure durability and strength.


The sheave pulleys are manufactured using advanced machinery and techniques for accuracy.


Each sheave pulley undergoes rigorous testing to ensure quality and performance standards are met.

Antirust Treatment

A special coating is applied to the sheave pulleys to protect them from corrosion and rust.

Separate Inspection

Every sheave pulley is individually inspected for any defects or imperfections before packaging.


Each sheave pulley is marked with relevant information for identification and traceability.

How do you adjust sheave pulleys?

  • Adjust the tension of the belt or rope connected to the sheave pulley
  • Ensure the sheave pulley is properly aligned and centered
  • Check for any signs of wear or damage on the sheave pulley
  • Use appropriate tools to make adjustments to the sheave pulley system
  • Follow manufacturer’s guidelines for adjusting sheave pulleys
  • Regularly inspect and maintain sheave pulleys to prevent issues
  • Consult a professional if unsure about adjusting sheave pulleys
