Single sheave pulleys have one wheel for guiding ropes or cables.

2. Double Sheave Pulleys

Double sheave pulleys have two wheels for better load distribution and reduced friction.

3. Triple Sheave Pulleys

Triple sheave pulleys offer even greater load-bearing capacity and smoother operation.

4. Fixed Eye Pulleys

Fixed eye pulleys have a stationary attachment point for rigging setups.

5. Swivel Eye Pulleys

Swivel eye pulleys have a rotating attachment point for flexible rigging options.

6. Snatch Blocks

Snatch blocks are specialized pulleys used for changing the direction of a line or cable.

What is a Sheave on a Pulley?

1. Definition

A sheave is a wheel with a groove used to guide ropes or cables in a pulley system.

2. Function

The sheave helps to reduce friction and wear on ropes or cables, allowing for smoother movement and increased efficiency.

3. Materials

Sheaves are typically made of metal, plastic, or composite materials depending on the application and load requirements.

4. Design

Sheaves can have different groove shapes and sizes to accommodate various rope or cable diameters and types.

5. Maintenance

Regular inspection and lubrication of sheaves are essential to ensure optimal performance and longevity of the pulley system.

What are Sheaves Used For?

1. Load Distribution

Sheaves help distribute the load evenly across ropes or cables, reducing strain and wear on the system.

2. Directional Changes

Sheaves are used to change the direction of a line or cable, allowing for versatile rigging configurations.

3. Tension Adjustment

By adjusting the position of sheaves, tension in the system can be fine-tuned for optimal performance.

4. Speed Control

Sheaves can be used to control the speed of movement in a pulley system, providing precise control over equipment on film sets.

5. Mechanical Advantage

Sheaves offer a mechanical advantage by multiplying the force applied, making it easier to lift heavy loads or operate equipment.

6. Rigging Solutions

Sheaves are an essential component of rigging setups for film sets, enabling smooth and efficient movements of equipment.

Process of Sheave Pulley

The mold is created based on the design specifications for the sheave pulley.


The raw materials are melted and poured into the mold to form the shape of 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 machinery and technology to meet industry standards.


Each sheave pulley undergoes rigorous testing to ensure quality and functionality before being released for use.

Antirust Treatment

Special coatings or treatments are applied to protect the sheave pulleys from corrosion and extend their lifespan.

Separate Inspection

Individual inspection is conducted on each sheave pulley to identify any defects or issues that need to be addressed.


Final markings are added to the sheave pulleys for identification and traceability purposes.

How do you adjust Sheave Pulleys?

1. Tension Adjustment

Loosen the attachment point and move the sheave to adjust tension in the system.

2. Positioning

Shift the sheave along the rigging setup to change the direction or alignment of ropes or cables.

3. Lubrication

Apply lubricant to the sheave to reduce friction and ensure smooth operation during adjustments.

4. Inspect Wear

Regularly check the condition of the sheave for signs of wear or damage that may affect performance.

5. Use Proper Tools

Utilize the appropriate tools and equipment to safely and effectively adjust sheave pulleys.

6. Seek Professional Help

If adjustments are challenging or complex, consult a professional technician or engineer for assistance.
