Steel Wire Rope
8x36WS+IWRC Wire Rope
An 8x36WS steel wire rope with an independent wire rope core (IWRC), designed for overhead lifting and hosting applications. It features high flexibility and improved fatigue life compared to 6x19 and 6x36 constructions due to smaller diameter wires in each strand. Available in diameters from 14mm to 42mm, with galvanized or ungalvanized surface finishes. The rope is supplied on wooden reels and used across construction, rigging, mining, oil and gas, and industrial lifting environments.

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 |
|---|---|
| 6×19 Wire Rope | The 8×36WS offers better flexibility and fatigue life but has lower abrasion resistance due to more surface wires |
| 6×36 Wire Rope | The 8×36WS has higher flexibility and better fatigue performance but is more sensitive to sheave condition and installation care |
| 6×36 FC Wire Rope | The 8×36WS IWRC has higher strength and crush resistance than a fiber core rope but is heavier and less flexible in tight bends |
| 6×37+FC Wire Rope | The 8×36WS IWRC has better fatigue life and strength but requires more careful sheave maintenance due to surface wire sensitivity |
Use Guide
How To Use And Inspect 8x36WS+IWRC Wire Rope
- Ensure sheave grooves are clean, smooth, and properly sized to match the rope diameter
- Inspect the rope for wire breaks, corrosion, or core extrusion before each use
- Avoid sharp bends and side loading that can damage the outer wires and core
- Use proper tensioning and spooling techniques during installation to prevent kinks
- Replace the rope if the number of broken wires exceeds the acceptable limit per industry standard
- Retire the rope if the core becomes visible or the rope shows permanent deformation
