How It Compares With The Alternatives
An honest read on where this pattern wins and where another one would serve you better.
| Alternative | Honest Trade Off |
|---|---|
| 6X19+FC | IWS core resists crushing better than fiber core under high load and compression, but is slightly stiffer and more expensive |
| 6X36+IWS | 6X36 has more wires and better flexibility but lower tensile strength and faster wear under high load |
| Galvanized rope with FC core | IWS core provides better core stability and longer life under repeated bending, but is heavier and more costly |
| Stainless steel rope with FC core | IWS core improves crush resistance and fatigue life in stainless steel, but the cost is higher and the rope is less flexible |
Use Guide
How To Use And Inspect Wre Rope 6X19+IWS
- Select rope grade and diameter based on the calculated working load and duty cycle
- Ensure the rope is used within the 4:1 design factor unless otherwise specified
- Inspect for kinks, broken wires, or core extrusion before each use
- Use proper sheaves with groove diameter at least 20 times the rope diameter
- Avoid sharp bends and side loading that can damage the IWS core
- Replace rope if more than 10% of wires are broken in any lay length
- Store in dry, shaded areas to prevent corrosion and UV degradation
