Process of Sheave Pulley

• Mold

  The mold for sheave pulleys is designed to create the desired shape and dimensions of the pulley.

• Casting

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

• Raw Materials

  High-quality raw materials are selected to ensure the durability and strength of the sheave pulley.

• Production

  The production process involves machining and finishing the sheave pulley to meet specific requirements.

• Testing

  Rigorous testing is conducted to check the quality, performance, and safety of the sheave pulley.

• Antirust Treatment

  Antirust treatment is applied to protect the sheave pulley from corrosion and ensure a longer lifespan.

• Separate Inspection

  Each sheave pulley undergoes a separate inspection process to guarantee its quality and adherence to standards.

• Marking

  Finally, the sheave pulley is marked with relevant information such as size, load capacity, and manufacturer details.

How do you adjust sheave pulleys?

1. Loosen the Set Screws

   To adjust a sheave pulley, start by loosening the set screws that secure it in place.

2. Rotate the Sheave

   Rotate the sheave to the desired position by adjusting its alignment or angle for proper tension and alignment.

3. Check Alignment

   Ensure the sheave is aligned correctly with other components to prevent wear and optimize performance.

4. Set the Tension

   Adjust the tension of the sheave pulley by tightening or loosening the ropes or cables connected to it.

5. Secure the Set Screws

   Once adjustments are made, securely tighten the set screws to lock the sheave pulley in place.

6. Test Operation

   Test the operation of the sheave pulley to ensure smooth movement and proper functionality after adjustments.
