Step-by-step guide to using the MARSHINE Φ1160 Large Diameter Universal Stringing Block.
1. Pre-installation preparation
Inspect the pulley block: Check for cracks, deformation or rust. Make sure the pulley rotates smoothly and the locking device is working properly.
Choose the mounting point: Select a sturdy structure such as a transmission tower or pole rated to withstand the load capacity of the pulley block.
Gather tools: Include winches, tensioners, and rigging hardware (e.g., shackles, slings) for a secure connection.
2. Install the threading pulley block
Attach to the structure: Secure the pulley block with a rated shackle or bolts. Align it to match the expected path of the cable to minimize angular stress.
Verify stability: Confirm that the mounting structure of MARSHINE Φ1160Large Diameter Universal Stringing Block can withstand dynamic loads during cable pulling.
3. Threading the wire
Feed the wire: Thread the cable through the pulley sheave, making sure it is centered to avoid uneven wear.
Attach the pulling equipment: Use a winch or tensioner to apply controlled force. Avoid sudden jerk to prevent cable damage.
4. Perform pulling operations
Monitor tension: Use a dynamometer to ensure tension remains within the rated capacity of the pulley.
Adjust alignment: If the cable is off track, pause and readjust the pulley or cable path.
5. Post-operation inspection
Clean pulleys: Remove debris and lubricate pulleys to maintain performance.
Store properly: Store the MARSHINE Φ1160Large Diameter Universal Stringing Block in a dry environment to prevent corrosion.
