The production process involves machining and finishing the sheave pulleys to meet specifications.


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

Antirust Treatment

Special coatings or treatments are applied to sheave pulleys to prevent rust and corrosion.

Separate Inspection

Each sheave pulley is individually inspected for defects or imperfections before packaging.


Sheave pulleys are marked with identification codes for traceability and quality control purposes.

How do you Adjust Sheave Pulleys?

1. Tension Adjustment

Use the appropriate tools to adjust the tension of the belt or rope on the sheave pulley.

2. Diameter Adjustment

For adjustable sheave pulleys, modify the diameter to achieve the desired performance in the elevator system.

3. Lubrication

Regularly lubricate the sheave pulley to reduce friction and ensure smooth operation.

4. Alignment Check
