Types of Sheave Pulleys

1. Fixed Pulleys

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

2. Movable Pulleys

Movable pulleys have a freely moving axle and are used to amplify the force applied to a rope or belt.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to provide a mechanical advantage for lifting heavy loads.

4. Block and Tackle Pulleys

Block and tackle pulleys use multiple pulleys in conjunction with each other to create a powerful lifting system.

5. Snatch Blocks

Snatch blocks are pulleys that can be attached to a rope or cable at any point, making them versatile for various applications.

6. Timing Belt Pulleys

Timing belt pulleys are used in conjunction with timing belts to transfer rotational motion between two shafts.

What is a sheave on a pulley?

  • A sheave on a pulley is a wheel with a groove used to guide and support a rope or belt.
  • It helps to change the direction of the force applied and allows for efficient transmission of power.
  • Sheaves are typically made of metal or other durable materials to withstand high loads and friction.
  • They come in various sizes and configurations to accommodate different applications.
  • Sheaves can be used in a wide range of industries, including construction, manufacturing, and transportation.

What are sheaves used for?

  • Sheaves are used to guide and support ropes or belts in a pulley system.
  • They help change the direction of a force and transmit power efficiently.
  • Sheaves are essential components in lifting and hoisting systems.
  • They are used in transportation systems such as elevators and cranes.
  • Sheaves are also utilized in manufacturing processes for material handling.
  • They play a crucial role in various industrial applications to facilitate movement and power transmission.

Process of Sheave Pulley

The design for the sheave pulley is created and a mold is made to form the shape of the pulley.


The molten metal is poured into the mold to create the solid pulley body.

Raw Materials:

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


The pulley is manufactured using precision techniques to meet quality standards.


Each sheave pulley undergoes rigorous testing to ensure performance and safety.

Antirust Treatment:

A protective coating is applied to prevent corrosion and extend the lifespan of the pulley.

Separate Inspection:

Each pulley is individually inspected to guarantee quality and functionality.


Finally, the sheave pulley is marked with specifications for identification and traceability.

How do you adjust sheave pulleys?

  • Adjust the tension of the belt or rope by loosening or tightening the fasteners on the pulley.
  • Ensure that the sheave pulleys are properly aligned for smooth operation.
  • Inspect the sheaves for any signs of wear or damage that may affect performance.
  • Use a belt tension gauge to measure and adjust the tension accurately.
  • Consult the manufacturer’s guidelines for specific instructions on adjusting sheave pulleys.
  • Regular maintenance and lubrication of the pulleys can help prevent the need for frequent adjustments.
  • If in doubt, seek professional assistance to ensure proper adjustment and operation of the sheave pulleys.
