Types of Sheave Pulleys

1. Fixed Sheave Pulleys

Fixed sheave pulleys have a stationary wheel that does not move, providing a stable point for the rope or cable to pass through.

2. Movable Sheave Pulleys

Movable sheave pulleys have a wheel that can move, allowing for adjustable tension and direction changes in the rope or cable.

3. Single Sheave Pulleys

Single sheave pulleys have one wheel for the rope or cable to pass through, providing a simple and efficient mechanical advantage.

4. Double Sheave Pulleys

Double sheave pulleys have two wheels for the rope or cable to pass through, offering increased mechanical advantage and reduced effort in lifting loads.

5. Snatch Blocks

Snatch blocks are specialized sheave pulleys with side plates that can be opened to easily insert the rope or cable without threading it through.

What is a Sheave on a Pulley?

1. Definition

A sheave is a wheel with a groove around its circumference, used with a belt, rope, or chain to change the direction of a force or transmit motion.

2. Function

The sheave on a pulley helps to guide and support the rope or cable, reducing friction and allowing for efficient movement and mechanical advantage.

3. Components

The sheave typically consists of a wheel, axle, and bearings, all working together to facilitate smooth rotation and operation.

4. Materials

Sheaves are commonly made of materials like steel, aluminum, or plastic, chosen for their strength, durability, and resistance to wear and tear.

5. Size and Design

Sheaves come in various sizes and designs to accommodate different rope diameters, load capacities, and installation requirements.

What are sheaves used for?

1. Mechanical Advantage

Sheaves are used to increase the mechanical advantage of a system, making it easier to lift heavy loads or apply force.

2. Directional Changes

Sheaves are used to change the direction of a force or motion, allowing for greater flexibility in the movement of ropes or cables.

3. Load Distribution

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

4. Tension Adjustment

Sheaves allow for easy adjustment of tension in ropes or cables, ensuring optimal performance and safety in various applications.

5. Speed Control

Sheaves can be used to control the speed of movement in a system by adjusting the diameter of the wheel or the number of sheaves used.

6. Versatility

Sheaves are versatile components that can be used in a wide range of applications, from industrial machinery to recreational equipment.

Process of Sheave Pulley

The mold is created based on the design specifications of the sheave pulley, ensuring precision and consistency in production.


The raw materials are melted and poured into the mold to form the shape of the sheave pulley, taking on its final structure.

Raw Materials

High-quality materials such as steel or aluminum are used to ensure durability, strength, and resistance to wear in the sheave pulley.


The sheave pulley is manufactured using advanced machinery and techniques to meet strict quality standards and specifications.


Each sheave pulley undergoes rigorous testing procedures to ensure performance, safety, and reliability in various conditions.

Antirust Treatment

A special treatment is applied to the sheave pulley to prevent rust and corrosion, extending its lifespan and maintaining its appearance.

Seperate Inspection

Every sheave pulley is individually inspected for quality control, identifying any defects or imperfections before packaging and shipping.


Each sheave pulley is marked with essential information such as load capacity, size, and production details for easy identification and traceability.

How do you adjust sheave pulleys?

1. Tension Adjustment

Loosen the bolts securing the sheave pulley and adjust the position of the wheel to increase or decrease tension in the rope or cable.

2. Lubrication

Apply lubricant to the bearings and axle of the sheave pulley to ensure smooth rotation and operation during adjustment.

3. Alignment

Check the alignment of the sheave pulley with the rope or cable to ensure proper engagement and prevent uneven wear or damage.

4. Inspection

Regularly inspect the sheave pulleys for signs of wear, damage, or misalignment, and make adjustments as needed to maintain optimal performance.
