Product overview
Line contacted wire rope is presented as a construction family covering multiple Fi, WS, S and SWS options in both 6-strand and 8-strand layouts. The current technical data includes diameter, tensile strength, approximate weight and minimum breaking load fields. Performance ranking between Fi, WS and S is not provided as verified conclusions in the source library.

Key technical data
Values vary by construction, core type, diameter and tensile-strength grade.
| Nominal diameter (mm) | Approx. weight (kg/100m) | Tensile strength (MPa) | Minimum breaking load (kN) |
|---|---|---|---|
| 8–120 (6-strand) | See data sheet | 1570–1960 | See construction table |
| 20–120 (8-strand) | See data sheet | 1670–2160 | See construction table |
Values vary by construction, core type, diameter and tensile-strength grade. Source MBL values are not working load limits (WLL/SWL).
Listed applications
The current CWRS technical data lists this rope family for the following uses.
Derricking / lifting / drawing
The current CWRS technical data lists derricking, lifting and drawing applications for this family.
Steel-core duty notes
Source notes for steel-core constructions reference shock, heated or squeezed service contexts such as electric shovel — as listed, not as a universal claim.
