Movable pulleys have a pulley that moves with the load, reducing the amount of force required to lift an object.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to create a system that provides mechanical advantage.

4. Block and Tackle Pulleys

Block and tackle pulleys use multiple pulleys in combination to increase the mechanical advantage for lifting heavy loads.

5. Snatch Blocks

Snatch blocks are designed for use with winches and ropes to change the direction of pull in a rigging system.

What is a sheave on a pulley?

1. Definition

A sheave is a pulley with a grooved wheel used in machinery to guide a cable or belt and change the direction of a force applied.

2. Function

Sheaves help to reduce friction and wear on cables, allowing for smoother and more efficient operation.

3. Components

A sheave typically consists of a wheel with a grooved rim and an axle at its center for rotation.

4. Materials

Sheaves are commonly made from materials such as steel, aluminum, or nylon, depending on the application.

5. Importance

Sheaves play a crucial role in various industries, including satellite maintenance, by facilitating the movement of cables and ropes.

What are sheaves used for?

1. Lifting Operations

Sheaves are used in lifting operations to change the direction of a force and provide mechanical advantage.

2. Rigging Systems

Sheaves are essential components of rigging systems for hoisting, lowering, and moving heavy loads.

3. Cable Management

Sheaves help in managing cables and ropes by guiding them through a specified path without causing damage.

4. Industrial Applications

Sheaves are widely used in industrial settings for conveyor systems, cranes, and other machinery.

5. Marine Industry

Sheaves are integral to marine operations for tasks such as sail handling and rigging on ships.

Process of Sheave Pulley

The mold for sheave pulleys is designed to create the desired shape and size of the pulley.


During casting, molten metal is poured into the mold to form the pulley’s structure.

Raw Materials

High-quality raw materials are used to ensure the durability and performance of the sheave pulley.


The production process includes machining and finishing to achieve the final design of the pulley.


Each sheave pulley undergoes rigorous testing to verify its quality and performance under various conditions.

Antirust Treatment

Antirust treatment is applied to protect the sheave pulley from corrosion and ensure a longer lifespan.

Separate Inspection

Each sheave pulley is individually inspected to guarantee compliance with quality standards and specifications.


Finally, the sheave pulley is marked with relevant information such as size, load capacity, and production details.

How do you adjust sheave pulleys?

1. Check Alignment

Ensure that the sheave pulleys are properly aligned to prevent unnecessary wear and tear.

2. Lubrication

Regularly lubricate the sheave pulleys to maintain smooth operation and reduce friction.

3. Tension Adjustment

Adjust the tension of the cables or belts running on the sheave pulleys to optimize performance.

4. Inspection

Periodically inspect the sheave pulleys for any signs of damage or wear and replace them if necessary.

5. Cleaning

Keep the sheave pulleys clean from debris and dirt to prevent interference with their operation.

6. Professional Maintenance

For complex adjustments or repairs, seek the assistance of a professional to ensure the proper functioning of the sheave pulleys.

7. Monitoring

Regularly monitor the performance of the sheave pulleys to address any issues promptly and prevent downtime.
