The mold for the sheave pulley is carefully designed to ensure accurate and precise production of the component.


Using high-quality raw materials, the sheave pulley is cast to create the desired shape and structure for optimal performance.

Raw Materials

The raw materials used in the production of sheave pulleys are selected for their durability, strength, and corrosion resistance.


The production process involves machining, assembly, and quality control measures to ensure the sheave pulleys meet high standards.


Each sheave pulley undergoes rigorous testing procedures to verify its performance, load capacity, and durability before being released for use.

Antirust Treatment

After production, the sheave pulleys are treated with anti-rust coatings to protect them from corrosion and prolong their lifespan.

Separate Inspection

Before packaging, each sheave pulley is individually inspected to check for any defects or imperfections that may affect its function.


Finally, each sheave pulley is marked with relevant information, such as size, load capacity, and manufacturing date, for easy identification and traceability.

How do you adjust sheave pulleys?

1. Loosen the Set Screw

Start by loosening the set screw on the sheave pulley to allow for adjustment of the position.

2. Rotate the Sheave

Gently rotate the sheave pulley to the desired position, ensuring that it aligns properly with the ropes or cables.

3. Tighten the Set Screw

Once the adjustment is complete, tighten the set screw securely to lock the sheave pulley in place.

4. Check Alignment

Verify that the sheave pulley is properly aligned and that there is no excessive friction or misalignment during operation.

5. Test the Pulley

Test the sheave pulley with a light load to ensure that it functions smoothly and efficiently after adjustment.

6. Regular Maintenance

Perform regular checks and maintenance on the sheave pulleys to ensure optimal performance and longevity in various applications.
