8×64 Class Round Strand Wire Rope

8×64 Class Round Strand Wire Rope

Product Introduction:

Designed for the most demanding marine, offshore, and heavy‑industrial lifting applications, our 8×64 Class Round Strand Wire Rope (construction code 8×64SFS) delivers an exceptional combination of strength, fatigue resistance, and operational stability. Manufactured in full accordance with GB/T 20067‑2006 — the Chinese national standard for large‑diameter steel wire ropes (40 mm to 160 mm) — this rope features an advanced 8‑strand design with 64 wires per strand, utilising a Seale‑Filler‑Seale (SFS) compound‑laid construction.

The SFS strand architecture combines two Seale‑type wire layers with strategically placed filler wires between them, creating a dense, compact cross‑section. This design offers several distinct advantages:

1.Superior breaking strength — the high metallic fill factor maximises the rope’s load‑bearing capacity for a given diameter.

2.Excellent abrasion and crush resistance — the smooth, compact outer surface withstands severe sheave wear and external pressure.

3.Enhanced fatigue endurance — the combination of point‑and‑line contact reduces internal stress concentrations, extending service life under repeated bending.

4.Reduced torque and improved spooling — the 8‑strand geometry inherently minimises rotation and twisting, ensuring stable, predictable performance during single‑fall hoisting and multi‑layer drum winding.

Two core configurations are available to match specific operational requirements:

*FC (Fiber Core) – provides natural elasticity and shock absorption, reducing peak dynamic loads and offering excellent flexibility for applications with frequent bending over small‑diameter sheaves. The fibre core also retains lubricant effectively, lowering maintenance frequency.

*IWR (Independent Wire Rope Core) – delivers a fully metallic core that maximises the rope’s metallic cross‑section, delivering the highest possible breaking loads, superior crush resistance, and outstanding performance in extreme tension and high‑pressure conditions. This option is the preferred choice for deep‑sea mooring, heavy‑lift cranes, and towing hawsers.

Technical Specifications：

The rope is available with various surface finishes — bright, galvanised, or specially lubricated — to ensure reliable corrosion resistance in seawater and humid marine atmospheres. Custom lengths, reeling drums, and end terminations (sockets, thimbles, or swaged fittings) can be supplied to meet specific project requirements.

Typical Applications Include:

*Ultra‑large shipbuilding gantry and floating cranes.

*Offshore platform cranes and subsea lift operations.

*Ship‑to‑ship mooring and towing systems.

*Floating production storage and offloading (FPSO) units.

*Deep‑sea salvage and dredging operations.

*Heavy‑lift industrial hoists and mining excavators.

Every production batch undergoes rigorous quality control — from raw material wire rod inspection through to final proof‑load testing. Our ropes can be supplied with certifications from leading classification societies, including API‑9A, ISO 9001, CCS, ABS, DNV, LR, and CE, ensuring full traceability and compliance with international marine standards.

With its robust SFS strand design, 8‑strand stability, and extraordinary load‑carrying capacity, the 8×64 Class Round Strand Wire Rope is the ultimate choice for marine and heavy‑industry professionals who demand uncompromising reliability, longevity, and safety in the world's most challenging lifting and mooring environments.
