6x29Fi+FC 6x29Fi+IWRC Galvanized Ungalvanizd Steel Cable Wire Rope

Gostern 6×29Fi Filler Wire Steel Wire Rope is manufactured from high quality carbon steel with excellent tensile strength, superior flexibility and outstanding fatigue resistance. This rope features 6 strands of 29 wires each with a specialized Filler Wire (Fi) construction – small filler wires are placed between larger main wires within each strand . This design allows for a greater number of wires without increasing strand diameter, resulting in superior flexibility and bending fatigue resistance compared to standard 6×19 or 6×37 constructions . Available with FC (Fiber Core) for maximum flexibility and shock absorption or IWRC (Independent Wire Rope Core) for increased strength, crushing resistance and stability in multi-layer spooling . Available in galvanized (zinc coated for corrosion resistance) or ungalvanized (bright) finish .

This Filler Wire Construction Rope offers an excellent balance of strength, flexibility, and fatigue resistance, making it ideal for applications with multiple bends over sheaves and high-speed operation . The 6×29Fi construction provides approximately 10-15% more wires than standard 6×19 rope of the same diameter, resulting in smoother operation and longer service life . It is widely used as Extra Flexible Hoist Cable for overhead cranes and hoists, as Crane Wire Rope for tower cranes and mobile cranes, as Mining Hoist Rope for mine hoisting, and as Multi Layer Spooling Rope for deep mine shafts and offshore applications . Available in diameters from 6mm to 52mm , with Grade 1570 MPa to 1960 MPa tensile strength options .

Construction Features:

• Filler wire design: Small wires fill the valleys between main wires, increasing metallic area

• Greater flexibility: More wires allow easier bending over sheaves

• Enhanced fatigue resistance: Reduced stress concentration per wire

• Smooth surface: Better spooling and reduced wear on drums

Core Selection Guide:

• FC Core: Best flexibility, shock absorption – ideal for single layer spooling

• IWRC Core: Maximum strength, excellent crush resistance – ideal for multi-layer spooling

Important Note: Do not exceed recommended working load limits. Regular inspection for wear, broken wires, and diameter reduction is required.
