2. Movable Pulleys

Movable pulleys have a moving axle and are used to reduce the amount of force needed to lift an object.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to provide a mechanical advantage for lifting heavy loads.

4. Block and Tackle Pulleys

Block and tackle pulleys consist of multiple pulleys working together to increase the lifting capacity.

5. Snatch Blocks

Snatch blocks are designed for use with winches and ropes to change the direction of the pulling force.

6. Wire Rope Sheaves

Wire rope sheaves are specially designed for wire ropes and are used in various industrial applications.

What is a sheave on a pulley?

  1. A sheave is a wheel with a grooved rim designed to hold a belt, rope, or cable.
  2. It helps change the direction of the force applied and provides mechanical advantage in lifting heavy loads.
  3. Sheaves are commonly used in pulley systems to transmit power and motion efficiently.
  4. They come in various sizes and materials to suit different applications.
  5. Sheaves play a crucial role in the smooth operation of pulley systems.

What are sheaves used for?

1. Lifting Heavy Loads

Sheaves are used to lift heavy loads by providing a mechanical advantage through pulley systems.

2. Transmitting Power

Sheaves help transmit power from one source to another by using belts, ropes, or cables.

3. Changing Direction of Force

They are used to change the direction of the force applied, making it easier to move objects.

4. Tensioning Systems

Sheaves are used in tensioning systems to maintain proper tension in belts and ropes.

5. Industrial Machinery

Sheaves are essential components in various industrial machinery for efficient operation.

Raw Materials

High-quality materials are used to ensure the durability and performance of the sheave pulley.


The sheave pulleys are manufactured with precision and attention to detail for optimal functionality.


Each sheave pulley undergoes rigorous testing to ensure quality and reliability.

Antirust Treatment

Special coatings are applied to protect the sheave pulleys from rust and corrosion.

Separate Inspection

Each sheave pulley is individually inspected to meet the highest standards of quality control.


Sheave pulleys are marked with specifications and identification for easy recognition and installation.

How do you adjust sheave pulleys?

  1. Check the alignment of the sheave pulleys to ensure smooth operation.
  2. Inspect the tension of the belts or ropes connected to the sheave pulleys.
  3. Adjust the position of the sheave pulleys to achieve the desired speed or torque.
  4. Use proper tools and equipment to make precise adjustments without causing damage.
  5. Regularly maintain and lubricate the sheave pulleys to prevent wear and tear.
  6. Consult the manufacturer’s guidelines for specific instructions on adjusting sheave pulleys.
  7. Seek professional help if you are unsure about how to adjust sheave pulleys correctly.
