2. Movable Pulleys

Movable pulleys have a movable axle and are used to provide mechanical advantage when lifting heavy loads.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to increase the lifting force with less effort.

4. Snatch Blocks

Snatch blocks are designed to change the direction of a rope or cable without twisting it.

5. Idler Pulleys

Idler pulleys are used to guide belts or ropes in a system and do not transmit power.

6. Wire Rope Sheaves

Wire rope sheaves are specifically designed for wire rope applications, providing smooth and efficient operation.

What is a Sheave on a Pulley?

  • A sheave is a wheel with a groove in the outer circumference to hold a belt, rope, or cable.
  • It is also known as a pulley wheel and is used to change the direction of a force or transmit power.
  • Sheaves can be made of various materials such as metal, plastic, or composite materials.
  • They are commonly used in industrial and commercial applications for lifting, lowering, or moving heavy loads.
  • Sheaves come in different sizes and configurations to suit specific requirements.

What are sheaves used for?

  • Sheaves are used to change the direction of a force in a pulley system.
  • They transmit power by guiding belts, ropes, or cables along their grooved circumference.
  • Sheaves provide mechanical advantage when lifting heavy loads by multiplying the force applied.
  • They are essential components in hoisting equipment, cranes, and other lifting devices.
  • Sheaves help to maintain tension in belts and ropes, ensuring smooth and efficient operation.
  • They are also used in various industrial and commercial applications for material handling and transportation.

Process of Sheave Pulley


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

The raw materials are melted and poured into the mold to form the pulley shape.

Raw Materials

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


The pulleys are manufactured using precision machinery to meet specific requirements.


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

Antirust Treatment

The pulleys are treated with anti-rust coatings to protect them from corrosion and extend their lifespan.

Separate Inspection

Each pulley is individually inspected to identify any defects or imperfections before packaging.


Each pulley is marked with essential information such as size, load capacity, and manufacturing date.

How do you adjust sheave pulleys?

  • Inspect the sheave pulley for any signs of wear or damage before making adjustments.
  • Check the alignment of the pulley to ensure smooth operation.
  • Adjust the tension of the belt or rope to prevent slipping or binding on the sheave.
  • Use the appropriate tools to tighten or loosen the sheave pulley as needed.
  • Regularly lubricate the sheave pulley to maintain optimal performance.
  • Consult the manufacturer’s guidelines for specific instructions on adjusting sheave pulleys.
  • If in doubt, seek professional assistance to avoid causing further damage to the pulley system.
