Types of Sheave Pulleys

1. Fixed Pulleys

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

2. Movable Pulleys

Movable pulleys have a pulley mounted on a movable axle, providing mechanical advantage for lifting heavy loads.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to increase the lifting force while requiring less effort.

4. Block and Tackle Pulleys

Block and tackle pulleys consist of multiple pulleys arranged in a block and tackle system to provide extra lifting power.

5. Snatch Blocks

Snatch blocks are designed to be used with winches and provide a change in the direction of the cable while under tension.

6. Wire Rope Pulleys

Wire rope pulleys are specifically designed to work with wire ropes, providing smooth and efficient operation for lifting and pulling tasks.

What is a Sheave on a Pulley

  • A sheave is a grooved wheel or pulley used with a belt or rope to change the direction or point of application of a pulling force.
  • Sheaves are commonly used in machinery and equipment to transmit power and facilitate movement.
  • They can be made of various materials such as metal, plastic, or composite, depending on the application.
  • Sheaves come in different sizes and configurations to suit specific needs and requirements.
  • They play a crucial role in the operation of pulley systems by providing support and guiding the rope or belt.

What are Sheaves used for?

1. Load Distribution

Sheaves are used to distribute loads evenly across multiple ropes or cables, reducing strain and wear on individual components.

2. Direction Change

Sheaves facilitate changes in the direction of ropes or cables, allowing for efficient movement and operation in various applications.

3. Mechanical Advantage

By using multiple sheaves in a pulley system, mechanical advantage can be gained to lift heavier loads with less effort.

4. Speed Control

Sheaves can be adjusted to control the speed of the pulley system, providing flexibility in different operations.

5. Tension Adjustment

Sheaves help in adjusting the tension of ropes or cables, ensuring optimal performance and safety of the system.

6. Power Transmission

Sheaves play a vital role in transmitting power from one component to another within a machinery or equipment setup.

The mold for the sheave pulley is carefully designed to ensure precision and accuracy in the final product.


During the casting process, molten metal is poured into the mold to create the desired shape of the sheave pulley.

Raw Materials

High-quality raw materials are used to manufacture sheave pulleys, ensuring durability and reliability in performance.


The production process involves machining and finishing the sheave pulley to meet the required specifications and standards.


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

Antirust Treatment

Sheave pulleys are treated with anti-rust coatings to protect them from corrosion and extend their lifespan.

Seperate Inspection

Before packaging, each sheave pulley is individually inspected to verify quality and functionality.


Finally, the sheave pulleys are marked with identification and specification details for easy identification and traceability.

How do you adjust sheave pulleys?

1. Loosen the Set Screw

Start by loosening the set screw on the sheave pulley using the appropriate tool.

2. Slide the Sheave

Adjust the position of the sheave by sliding it along the shaft to the desired location.

3. Realign the Belt

Ensure the belt is properly aligned on the sheave pulley after making the adjustment.

4. Tighten the Set Screw

Once the adjustment is made, tighten the set screw securely to lock the sheave in place.

5. Check Tension

Check the tension of the belt to ensure it is within the recommended range for optimal performance.
