Wire Rope End Fittings
Every wire rope needs a termination, and the termination is often the weakest point in the assembly. The right fitting depends on the load, the rope and whether the connection is permanent. This guide explains the main wire rope end fittings.
Why the Termination Matters
A wire rope is only as strong as the fitting that ends it. A poor termination can slip, crush the rope or fail under load, even if the rope itself is rated correctly.
Wire Rope Clips
Wire rope clips form an eye with a U-bolt and saddle. They are reusable and easy to install, which makes them popular for temporary and field terminations. Use the correct number of clips and re-tighten after the first load.
Ferrules and Sleeves
Ferrules and aluminum sleeves are pressed or swaged onto the rope to form a permanent eye. They give a clean, compact termination and are common in manufactured slings.
Thimbles
A thimble lines the inside of the eye to protect the rope from wear and kinking. It is used with clips or ferrules and keeps the eye open for a shackle or hook.
Swages
A swage fitting is compressed onto the rope with a swaging machine. Swaged terminations are strong and streamlined, and are used in lifting and structural applications.
How to Choose a Wire Rope End Fitting
- Match the fitting to the rope diameter.
- Choose clips for temporary or field work, ferrules or swages for permanent assemblies.
- Always use a thimble where the eye will take a shackle or hook.
- Check the WLL and the termination efficiency.
FAQ
What is the strongest wire rope termination?
