The mold for sheave pulleys is carefully designed to ensure accurate and consistent production.


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

Raw Materials

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


The pulleys are manufactured with precision engineering techniques to meet quality standards.


Each sheave pulley undergoes rigorous testing to ensure proper function and load capacity.

Antirust Treatment

Special coatings or treatments are applied to prevent corrosion and extend the lifespan of the pulley.

Separate Inspection

Finished pulleys are individually inspected for defects or imperfections before packaging.


Each sheave pulley is marked with identification codes for traceability and quality control purposes.

How do you adjust sheave pulleys?

1. Tension Adjustment

Adjust the tension of the rope or cable on the sheave pulley to ensure smooth operation.

2. Alignment Correction

Check and correct any misalignment of the sheave pulleys to prevent premature wear and tear.

3. Lubrication

Regularly lubricate the sheave pulleys to reduce friction and maintain optimal performance.

4. Inspection

Periodically inspect the sheave pulleys for signs of wear, damage, or misalignment that may require adjustment.

5. Load Distribution

Ensure that the load is evenly distributed on the sheave pulleys to prevent overloading and premature failure.

6. Professional Maintenance

Consult with a professional technician for complex adjustments or maintenance tasks on sheave pulleys.
