Structure of U-Bolt Anchor Turnbuckle
- Turnbuckle Body:
- Cylindrical body with threaded ends for connecting bolts or U-bolts.
- Made of stainless steel, galvanized steel, or aluminum alloy for corrosion resistance.
- U-Bolt:
- U-shaped bolt with threaded ends for connecting chain or cable.
- Secured with nuts or plates to hold the chain firmly.
- Adjustment Pin & Lock Nut:
- Used to adjust the chain tension by rotating threads in opposite directions.
- Optional lock nut prevents loosening during operation.
Working Principle of U-Bolt Anchor Turnbuckle
- Rotating the turnbuckle body shortens or lengthens the bolts, adjusting chain or cable tension.
- Tightening reduces slack and increases stability.
- Loosening allows flexible adjustment or removal.
Applications of U-Bolt Anchor Bolt & Turnbuckle
- Marine & Port Industry:
- Used in mooring systems to adjust anchor chain tension, preventing vessel drifting.
- Installed in fender systems to secure marine fenders in position during berthing.
- Construction & Industrial:
