Introduction to Small Cable Sheaves

  • Durable Material: Small cable sheaves are made from high-quality materials that ensure durability and longevity.
  • Smooth Operation: These sheaves are designed for smooth and efficient operation, reducing friction and wear.
  • Various Sizes: Small cable sheaves come in a variety of sizes to suit different cable diameters and loads.
  • Easy Installation: They are easy to install and can be used in a wide range of applications.
  • High Load Capacity: Despite their small size, these sheaves have a high load capacity, making them suitable for various tasks.

Types of Sheave Pulleys

1. Fixed Pulleys

Fixed pulleys have a stationary axle and are used to redirect the cable without any mechanical advantage.

2. Movable Pulleys

Movable pulleys have a pulley attached to a hook or other mechanism that allows it to move, providing mechanical advantage.

3. Compound Pulleys

Compound pulleys combine fixed and movable pulleys to provide even greater mechanical advantage.

4. Snatch Blocks

Snatch blocks have a side plate that opens, allowing the cable to be easily inserted without threading it through.

5. Wire Rope Pulleys

Wire rope pulleys are designed specifically for use with wire ropes, providing a smooth surface for the cable to run on.

6. Nylon Pulleys

Nylon pulleys are lightweight and durable, making them suitable for various applications where weight is a concern.

What is a sheave on a pulley?

  • A sheave on a pulley is a wheel with a groove that holds a cable or rope, allowing it to move smoothly.
  • Sheaves are typically made of metal or nylon and come in various sizes to accommodate different cables.
  • They are essential components in pulley systems, providing support and guidance for the cable.
  • Sheaves help to reduce friction and wear on the cable, prolonging its lifespan.
  • They can be used in various industries, such as construction, mining, and manufacturing.

What are sheaves used for?

  • Sheaves are used to guide cables or ropes in a pulley system.
  • They help to change the direction of the cable without causing excessive wear.
  • Sheaves provide mechanical advantage, making it easier to lift heavy loads.
  • They are essential in hoisting and lifting equipment, such as cranes and elevators.
  • Sheaves are also used in industrial machinery and agricultural equipment for various applications.
  • They play a crucial role in the smooth operation of pulley systems, ensuring efficiency and safety.

The mold for sheave pulleys is carefully crafted to ensure the desired shape and dimensions.


The molten metal is poured into the mold to create the sheave pulley’s shape.

Raw Materials

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


The sheave pulley is manufactured with precision and attention to detail to meet quality standards.


Each sheave pulley undergoes rigorous testing to ensure it meets performance requirements.

Antirust Treatment

The sheave pulley is treated to prevent rust and corrosion, increasing its longevity.

Seperate Inspection

Each sheave pulley is inspected separately to guarantee quality and functionality.


Finally, the sheave pulley is marked with relevant information for identification purposes.

How do you adjust sheave pulleys?

  • Adjust the tension of the cable by moving the sheave pulley closer or farther from the load.
  • Check the alignment of the sheave pulleys to ensure smooth operation.
  • Inspect the sheave pulley for any signs of wear or damage that may affect its performance.
  • Use a sheave pulley with the correct groove size to match the diameter of the cable.
  • Ensure that the sheave pulley is securely fastened to prevent slippage during operation.
  • Regularly lubricate the sheave pulley to reduce friction and prolong its lifespan.
  • Consult the manufacturer’s guidelines for specific instructions on adjusting sheave pulleys.
