The mold for the sheave pulley is created to ensure accurate and consistent production of the desired shape and size.


During the casting process, molten metal is poured into the mold to form the sheave pulley’s structure.

Raw Materials

High-quality raw materials are used to manufacture the sheave pulley, ensuring durability and performance.


The production process involves shaping, machining, and finishing the sheave pulley to meet quality standards.


Each sheave pulley undergoes rigorous testing to ensure it meets safety and performance requirements before being used.

Antirust Treatment

Antirust treatment is applied to the sheave pulley to protect it from corrosion and extend its lifespan.

Separate Inspection

Each sheave pulley is individually inspected for quality control to identify any defects or issues that need to be addressed.


After passing inspection, the sheave pulley is marked with relevant information such as size, load capacity, and production details.

How do you Adjust Sheave Pulleys?

1. Loosen the Fasteners

Start by loosening the fasteners that secure the sheave pulley in place to allow for adjustment.

2. Align the Sheave

Ensure the sheave is properly aligned with the rope or cable to prevent any friction or misalignment during operation.

3. Adjust Tension

Adjust the tension on the rope or cable by moving the sheave to the desired position for optimal performance.

4. Secure the Fasteners

Once the adjustment is made, secure the fasteners back in place to lock the sheave pulley in its new position.

5. Test Operation

Test the sheave pulley to ensure it moves smoothly and effectively after making the necessary adjustments.

6. Regular Maintenance

Perform regular maintenance on the sheave pulleys to keep them in optimal condition and prevent the need for frequent adjustments.
