The raw materials are melted and poured into the mold to create the shape of the sheave pulley.

Raw Materials

High-quality materials such as stainless steel or ceramic are used to ensure durability and performance.


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


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

Antirust Treatment

Special coatings or treatments are applied to the pulleys to prevent corrosion in harsh environments.

Seperate Inspection

Each pulley is individually inspected to maintain high quality and consistency in production.


Sheave pulleys are marked with identification codes or labels for easy identification and tracking.

How do you adjust sheave pulleys?

  1. Inspect the pulley for any signs of wear or damage.
  2. Loosen the bolts or fasteners holding the pulley in place.
  3. Adjust the position of the pulley to the desired location.
  4. Tighten the bolts or fasteners securely to secure the pulley in place.
  5. Check the alignment and operation of the pulley to ensure proper functioning.
  6. Regularly maintain and lubricate the pulley to prevent issues and ensure smooth operation.
  7. Seek professional help if adjustments are complex or require specialized knowledge.
