Types of Sheave Pulleys

1. Fixed Pulleys

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

2. Movable Pulleys

Movable pulleys have a movable axle and are used to amplify the force applied in a surveillance system.

3. Compound Pulleys

Compound pulleys are a combination of fixed and movable pulleys, offering both direction change and force amplification in surveillance systems.

4. Snatch Blocks

Snatch blocks are designed to be used with ropes and cables to change the direction of the force in surveillance systems.

5. Idler Pulleys

Idler pulleys are used to route the belt in a surveillance system and maintain tension.

6. Rope Pulleys

Rope pulleys are specifically designed for use with ropes in surveillance systems to change direction or provide mechanical advantage.

What is a sheave on a pulley?

1. Definition

A sheave on a pulley is a wheel or roller with a groove used to guide and support a cable or rope in a surveillance system.

2. Function

The sheave helps to change the direction of the force and maintain tension in the cable or rope in a surveillance system.

3. Components

The sheave consists of a wheel, axle, and bearings, providing smooth movement and support for the cable or rope.

4. Types

There are different types of sheaves, such as single groove, double groove, and V-groove, each designed for specific applications in surveillance systems.

5. Materials

Sheaves are typically made from materials like steel, aluminum, or plastic, depending on the load and environmental conditions in surveillance systems.

What are sheaves used for?

1. Load Distribution

Sheaves are used to distribute the load evenly across multiple cables or ropes in a surveillance system.

2. Direction Change

Sheaves help to change the direction of the force applied by the cables or ropes in a surveillance system.

3. Tension Maintenance

Sheaves are essential for maintaining tension in the cables or ropes to ensure smooth operation in surveillance systems.

4. Mechanical Advantage

Sheaves provide mechanical advantage by amplifying the force applied to the cables or ropes in surveillance systems.

5. Noise Reduction

Sheaves help to reduce noise and vibration by providing smooth movement and alignment of the cables or ropes in surveillance systems.

6. Energy Efficiency

Sheaves contribute to energy efficiency by reducing friction and wear on the cables or ropes in surveillance systems, leading to longer service life.

Process of Sheave Pulley


The mold is created to shape the sheave pulley according to the design specifications.

The molten raw materials are poured into the mold to form the sheave pulley.

Raw Materials

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


The sheave pulleys are manufactured with precision and attention to detail to meet quality standards.


Each sheave pulley undergoes rigorous testing to ensure reliability and performance in surveillance systems.

Antirust Treatment

The sheave pulleys are treated with anti-rust coatings to protect against corrosion in various environments.

Separate Inspection

Each sheave pulley is inspected individually to ensure quality control and adherence to specifications.


Finally, the sheave pulleys are marked with relevant information for identification and traceability.

How do you adjust sheave pulleys?

1. Tension Adjustment

Adjust the tension of the cables or ropes by moving the sheave pulley to the desired position.

2. Alignment Correction

Ensure the sheave pulleys are properly aligned to prevent friction and wear on the cables or ropes.

3. Lubrication Maintenance

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

4. Inspect for Wear

Check the sheave pulleys for signs of wear and replace them if necessary to maintain optimal performance.

5. Secure Mounting

Ensure the sheave pulleys are securely mounted to prevent movement or misalignment during operation.

6. Consult Manufacturer Guidelines

Refer to the manufacturer’s guidelines for specific instructions on adjusting the sheave pulleys for optimal performance.
