Separate Inspection

Each sheave pulley is individually inspected to guarantee quality and precision before assembly.


Sheave pulleys are marked with specifications and branding for identification and traceability.

How do you adjust sheave pulleys?

1. Tension Adjustment

Adjust the tension of the ropes or cables on the sheave pulley to control movement.

2. Position Adjustment

Move the sheave pulley to a different position to change the direction of force.

3. Lubrication

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

4. Bearing Replacement

If the bearings are worn out, replace them to maintain the efficiency of the sheave pulley.

5. Alignment Check

Check the alignment of the sheave pulley to prevent uneven wear and tear on ropes or cables.

6. Load Adjustment

Adjust the load on the sheave pulley to prevent overloading and ensure safe operation.
