6×61FWS Class Round Strand Wire Rope

6×61FWS Class Round Strand Wire Rope

Product Introduction:

Engineered for the most grueling marine lifting and anchoring tasks, our 6×61FWS Class Round Strand Wire Rope represents a significant advancement in large-diameter heavy-lift technology. Manufactured in strict compliance with the GB/T 20067-2006 standard, the "FWS" (Fill Wire Seale) designation indicates a specialized strand construction. This configuration utilizes filler wires to tightly pack the inner strands, resulting in a higher metallic fill factor, significantly enhanced radial support, and superior structural stability compared to standard 6×61 ropes. It is the ultimate reliable solution for massive commercial vessels and extreme offshore operations.

Construction Details & Core Options:

The 6×61FWS 6-strand design ensures excellent torque balance and flexibility even at large diameters, while the unique filler wire arrangement minimizes internal friction and improves wear resistance. Available in two distinct core configurations:

*6X61FWS + FC (Fiber Core): Built with a high-quality synthetic fiber core, this variant provides superior shock absorption and high pliability. It is the preferred choice for heavy towing, offshore hauling, and general mooring applications where the rope must absorb sudden dynamic loads without stiffness.

*6X61FWS + IWR (Independent Wire Rope Core): Equipped with a robust independent steel wire core, this configuration offers unmatched resistance to radial crushing and compression. It is highly recommended for multi-layer spooling on heavy-duty winch drums and deep-sea anchor handling, where internal structural integrity is paramount under extreme pressure.

Primary Marine & Industrial Applications:

Thanks to its high fill factor, extreme strength, and reliable 6-strand balance, this heavy-lift cable is primarily utilized for:

*VLCC (Very Large Crude Carrier) mooring and hawser applications.

*Deep-sea offshore platform anchor handling and positioning.

*Ultra-large heavy-lift floating cranes and port-side gantry hoists.

*Ocean-going salvage and multi-point towing operations.

*Heavy-duty deck winch systems requiring high internal compression resistance.

Handling & Operational Care:

Given its impressive weight and extreme working loads, specialized heavy-duty sheaves and proper reel spooling are critical during installation. For the +IWR core variant, it is vital to maintain a strict lubrication schedule to prevent internal fretting fatigue between the steel core and outer strands, ensuring a long operational life in harsh saltwater environments.
