Single sheave pulleys have a single wheel for the rope to pass over, suitable for light-duty applications.

2. Double Sheave Pulleys

Double sheave pulleys have two wheels for the rope to pass over, providing increased mechanical advantage for heavier loads.

3. Fixed Sheave Pulleys

Fixed sheave pulleys have a stationary wheel and are ideal for applications where the direction of the force remains constant.

4. Swivel Sheave Pulleys

Swivel sheave pulleys have a rotating wheel, allowing for easy movement and change in direction of the rope.

5. Snatch Sheave Pulleys

Snatch sheave pulleys are designed for quick attachment and release of ropes, making them ideal for rescue and emergency situations.

6. Tandem Sheave Pulleys

Tandem sheave pulleys have multiple wheels in a row, providing increased mechanical advantage for heavy loads.

What is a Sheave on a Pulley

1. Function

A sheave on a pulley is a wheel with a groove used to guide and support a rope or cable, allowing for mechanical advantage in lifting or moving objects.

2. Material

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

3. Size

The size of a sheave on a pulley can vary depending on the diameter of the rope or cable it is designed to accommodate.

4. Rotation

Sheaves can be fixed or swiveling, with swivel sheaves allowing for greater flexibility in changing the direction of the rope.

5. Maintenance

Regular inspection and maintenance of sheaves are essential to ensure smooth operation and prevent wear and tear on the ropes or cables.

What are Sheaves Used For?

1. Lifting and Hoisting

Sheaves are commonly used in lifting and hoisting applications to provide mechanical advantage for moving heavy loads.

2. Rigging and Rope Access

Sheaves are essential components in rigging and rope access systems, allowing for smooth movement and redirection of ropes.

3. Rescue Operations

Sheaves are used in rescue operations to facilitate the safe and efficient movement of individuals in emergency situations.

4. Industrial Machinery

Sheaves play a vital role in industrial machinery for transmitting power and motion between rotating shafts.

5. Construction and Maintenance

Sheaves are used in construction and maintenance activities for tasks such as lifting equipment and materials to elevated heights.

6. Transportation

Sheaves are utilized in transportation systems for applications such as cable cars and ski lifts to move passengers and cargo efficiently.

Process of Sheave Pulley

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


Raw materials are melted and poured into the mold to create the solid structure of the sheave pulley.

Raw Materials

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


The production process involves shaping, machining, and finishing the sheave pulleys to meet specific design requirements.


Each sheave pulley undergoes rigorous testing to ensure quality, performance, and safety standards are met.

Antirust Treatment

Sheave pulleys are treated with anti-rust coatings to protect against corrosion and prolong their lifespan.

Separate Inspection

Each sheave pulley is individually inspected for quality control before being packaged and shipped.


Sheave pulleys are marked with relevant information such as size, load capacity, and production date for easy identification and traceability.

How do you adjust sheave pulleys?

1. Loosen the Set Screw

Start by loosening the set screw on the sheave pulley to allow for adjustment.

2. Slide the Sheave

Slide the sheave along the shaft to the desired position for proper alignment and tension.

3. Re-tighten the Set Screw

Once the sheave is adjusted, re-tighten the set screw securely to lock it in place.

4. Check Alignment

Ensure that the sheave is properly aligned with other components and the belt for smooth operation.

5. Test Operation

Test the sheave pulley to confirm that it is functioning correctly and making the necessary adjustments if needed.

6. Regular Maintenance

Perform regular maintenance checks on sheave pulleys to ensure optimal performance and longevity.
