6V×30 Class Shaped Strand Wire Rope

6V×30 Class Shaped Strand Wire Rope

Product Introduction:

The 6V×30 Class Shaped Strand Wire Rope is a high-performance steel wire rope engineered for demanding marine and offshore applications. Manufactured in compliance with GB/T 8918-2006 – the Chinese national standard for Steel wire ropes for important purposes – this rope delivers exceptional strength, durability, and reliability in the harshest maritime environments.

Construction & Design：

The designation 6V×30 signifies a rope constructed with 6 strands, each featuring a triangular (V-shaped) strand profile and composed of 30 individual wires. This triangular or “flattened strand” configuration is the defining feature of the product.

Unlike conventional round-strand ropes, the flattened strand design offers several structural advantages:

1.Greater steel density – More steel in the cross-section compared to standard round-strand ropes of equal diameter

2.Enhanced surface contact – The flattened shape creates a bearing surface with more contact points on sheaves and drums, distributing weight and wear more uniformly

3.Crush resistance – The compact triangular structure resists crushing and distortion under heavy loads

4.Smoother exterior – The rope surface forms a more continuous, smooth circle than regular round-strand wire rope, reducing wear on equipment

Revised Paragraph For Core Options:

The 6V×30 Class Shaped Strand Wire Rope is offered with two distinct core types to suit varying operational demands. The first is the Fiber Core (FC), which provides lighter weight and greater flexibility, making it a suitable choice for general marine applications where bending fatigue and handling ease are priorities. The second is the Independent Wire Rope Core (IWRC), which consists of a separate wire rope strand at the center; this design delivers significantly higher strength, superior resistance to crushing and distortion, and enhanced structural stability, making it the preferred option for heavy‑duty lifting, deep‑water mooring, and high‑load offshore operations where maximum reliability is essential.

Technical Specifications：

Marine Advantages:

The 6V×30 Class Shaped Strand Wire Rope is exceptionally well-suited for marine environments due to:

1.Superior wear resistance – The flattened strand design minimizes abrasion against sheaves and drums, extending service life

2.High fatigue resistance – Enhanced wire-to-wire contact and stress distribution reduce internal fatigue

3.Excellent strength-to-weight ratio – Delivers approximately 10% greater strength than standard round-strand ropes of equal diameter

4.Corrosion resistance – Available in galvanized or bright (ungalvanized) surface finishes to withstand saltwater exposure

5.Compliance with international standards – Manufactured to GB, DIN, BS, JIS, ASTM, API, and ISO standards

Marine Applications:

This wire rope is widely deployed across the maritime industry for:

*Mooring lines – Securing vessels at docks and offshore installations.

*Towing ropes – Ship-to-ship and harbour towing operations.

*Cargo hoisting – Shipboard cranes and derricks for loading/unloading.

*Salvage operations – Heavy-lift and recovery work.

*Offshore engineering – Drilling rigs, platform cranes, and subsea lifting gear.

*Winch ropes – Mooring winches and towing winches.

Quality Assurance:

The 6V×30 Class Shaped Strand Wire Rope is backed by certifications including ISO 9001, CCS (China Classification Society), ABS (American Bureau of Shipping), DNV, BV, CE, and SGS. Rigorous quality control ensures safe and reliable operation under the most demanding marine conditions.
