Product Overview


Covering seven configurations—6×19-FC, 6×19S-FC (Seale lay), 6×19W-FC (Warrington lay), 6×25Fi-FC (Fill lay), 6×26WS-FC (Wave-Shaped strands), 6×37-FC (37-wire strands), and 6×36WS-FC (Wave-Shaped 36-wire strands)—it caters to medium-load applications. Available in diameters from 6 mm to 80 mm, it offers tensile strength of 1570 MPa to 1960 MPa, meeting ISO 9001 and GB/T 20118 standards. The FC core (typically polypropylene or jute) absorbs operational shocks and reduces overall rope weight by 18% compared to IWRC, making it ideal for applications where maneuverability and cost are key, such as agricultural machinery and light construction.


6x19+FC Steel Wire Rope


Product Features


FC Core Advantages

Shock Absorption: The fibre core (FC) absorbs 40% more operational shock than IWRC, protecting equipment from sudden load spikes—critical for manual winches and agricultural lifts.

Lightweight Maneuverability: FC reduces rope weight by 18%, enabling easier manual handling (e.g., by farm workers or construction crews) without compromising load capacity.


Configuration-Specific Traits

6×19/6×19S/6×19W-FC: 19-wire strands for medium static loads (e.g., warehouse hoists); Seale lay (6×19S) for smooth spooling, Warrington lay (6×19W) for cost-efficient strength.

6×25Fi/6×37-FC: 25/37-wire Fill lay designs enhance flexibility, suitable for small pulleys (≥18× rope diameter) in dynamic applications (e.g., tractor winches).

6×26WS/6×36WS-FC: Wave-shaped strands reduce friction, extending service life in high-cycle uses (e.g., retail warehouse conveyors) while maintaining FC’s lightweight benefit.


Applications


Agricultural & Rural Uses

6×19-FC (6-16 mm diameter) powers tractor winches, hay balers, and irrigation system lifts—its lightweight design allows easy attachment to farm machinery, and FC core resists dust accumulation in rural environments.


Light Construction & Logistics

6×37-FC (10-30 mm) is used in mini tower cranes (for residential construction) and warehouse hoists (cargo loading); 6×26WS-FC (12-40 mm) suits retail distribution center conveyors, where low friction and maneuverability are essential.


FAQ


How does FC compare to IWRC for agricultural use?

FC is preferred—its lighter weight (18% less than IWRC) and shock absorption make it easier to handle manually, and it resists dust better than IWRC in farm environments.


What is the maximum safe working load for a 20 mm 6×19S-FC rope?

At 1770 MPa tensile strength, the 20 mm 6×19S-FC has a minimum breaking load of 420 kN; with a 5:1 safety factor, the maximum safe working load is 84 kN.


Is FC core resistant to moisture?

Yes, polypropylene FC cores are moisture-resistant (jute cores are treated with water-repellent coating), making the rope suitable for outdoor agricultural use (e.g., rain-fed farm irrigation lifts).
