Swivel Forerunner for Reliable Anchor Chain Connection and Smooth Mooring

Swivel Forerunner / Swivel Piece include End Link, Enlarged Link, Swivel, Enlarged Link and Common Link, commonly used to connecting End Shackle and anchor chains. 

Joining the stud link chain and the anchor, a 3-link or 4-link swivel forerunner is the most common swivel-connector in use today due to its optimal design. 

The anchor-side of the swivel forerunner is open for fitting a "D" end shackle. The other side is a common link to fit a Kenter joining shackle. The swivel forerunner is produced to ISO 1704 standards.

• HIGH-PERFORMANCE SWIVEL FORERUNNER FOR MARINE AND OFFSHORE MOORING

  The Swivel Forerunner is a critical connecting component that links the anchor to the anchor chain, featuring an integrated swivel to prevent chain twisting and allow free rotation during anchoring. 

  It ensures steady load distribution, safer handling, and longer equipment life in harsh marine environments.

  Each Swivel Forerunner assembly consists of a connecting shackle, swivel, and end link, made from Grade 2 or Grade 3 Alloy steel.

• OPTIMIZED STRUCTURE FOR SMOOTH ROTATION AND LOAD STABILITY

  Designed with a precision-engineered rotating mechanism, the Swivel Forerunner enables flexible movement between chain and anchor, minimizing chain deformation and enhancing mooring reliability under dynamic load conditions.

  Our Swivel Forerunners use high-strength alloy steel with self-lubricating bronze bushings, delivering up to 35% smoother rotation and reduced torsion fatigue.

  Ask our engineers how our improved swivel design enhances anchor handling and extends your mooring equipment lifespan.

• ANTI-CORROSION TREATMENT FOR LONG-TERM MARINE DURABILITY

  To withstand saltwater, humidity, and temperature variation, each Swivel Forerunner undergoes a multi-layer surface protection process that ensures exceptional corrosion resistance in marine operations.

  Surface finishing options include hot-dip galvanizing, black bitumen coating, zinc-rich marine epoxy, and optional Dacromet coating tested for 1000-hour salt spray resistance.
