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

2. Movable Pulleys:

Movable pulleys have a movable axle and are used to provide mechanical advantage in lifting loads.

3. Compound Pulleys:

Compound pulleys combine both fixed and movable pulleys to increase the mechanical advantage even further.

4. Block and Tackle Pulleys:

Block and tackle pulleys consist of multiple pulleys working together to lift heavy loads with ease.

5. Snatch Blocks:

Snatch blocks are designed for use with winches to change the direction of a load or to increase the line of pull.

6. Idler Pulleys:

Idler pulleys are used to route a belt around a system and do not provide any mechanical advantage.

What is a Sheave on a Pulley?

1. Definition:

A sheave is a wheel or pulley with a grooved rim around which a belt or rope passes. It is used to change the direction of a force or transmit power.

2. Function:

The sheave provides a surface for the belt or rope to grip onto, allowing for the transfer of motion or power between two points.

3. Materials:

Sheaves are commonly made from materials such as steel, aluminum, or plastic, depending on the application and load requirements.

4. Sizes:

Sheaves come in various sizes to accommodate different belt widths and loads, ensuring optimal performance in the pulley system.

5. Installation:

Sheaves are mounted onto shafts or axles and secured in place to ensure smooth rotation and efficient operation.

What are Sheaves used for?

1. Power Transmission:

Sheaves are used to transmit power from one rotating element to another, such as in engine systems or conveyor belts.

2. Lifting Systems:

Sheaves are essential components in lifting systems, providing mechanical advantage to lift heavy loads with ease.

3. Material Handling:

Sheaves are used in material handling equipment like cranes and hoists to move goods efficiently and safely.

4. Automotive Applications:

Sheaves are found in automotive engines to drive accessories like alternators, water pumps, and power steering systems.

5. Industrial Machinery:

Sheaves play a crucial role in various industrial machinery applications, providing smooth and reliable operation.

6. Agricultural Machinery:

Sheaves are used in agricultural machinery for tasks like irrigation systems, harvesting equipment, and tractors.

Process of Sheave Pulley:


The mold for the sheave pulley is created based on the design specifications to ensure accurate production.

The molten metal is poured into the mold to form the sheave pulley’s shape and structure.

Raw Materials:

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


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


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

Antirust Treatment:

The sheave pulley is treated with anti-rust coatings to protect it from corrosion and extend its lifespan.

Seperate Inspection:

Each sheave pulley is inspected individually to ensure it meets all specifications and quality standards.


The sheave pulley is marked with identification tags for easy tracking and maintenance purposes.

How do you adjust sheave pulleys?

1. Tension Adjustment:

Adjust the tension of the belt or rope on the sheave pulley to ensure proper alignment and operation.

2. Position Adjustment:

Move the sheave pulley along the shaft to change the positioning for optimal performance.

3. Belt Replacement:

If the belt is worn or damaged, replace it with a new one to maintain the efficiency of the sheave pulley system.

4. Lubrication:

Regularly lubricate the sheave pulley bearings to reduce friction and extend the lifespan of the system.

5. Alignment Check:

Check the alignment of the sheave pulleys to ensure they are parallel and operating smoothly.

6. Load Adjustment:

Adjust the load on the sheave pulleys to prevent overload and ensure safe operation.
