Wire rope

Wire rope slings

Flemish-rolled eyes, IWRC core, EIPS strength — swaged and proof tested in our own shop. Configure it and get the rated capacity.

Build your sling

Construction, legs, diameter, hitch, length

Wire rope is the biggest thing we make. Every sling is built to your length, tagged, and proof tested before it ships.

Know the load but not the size? The sling calculator works out angle, leg length and the load per leg, then points back here.

Constructions

Six ways we build a wire rope sling

The Flemish-rolled eye covers most work. The rest exist because some jobs need flexibility, a wider bearing surface, or no eyes at all.

Two-leg wire rope sling bridle
A two-leg bridle. The configurator above draws the leg count you pick.

Flemish-rolled eye

The standard mechanically spliced sling. Strands are unlaid and re-rolled into the eye, then the sleeve is swaged. Strongest and most common.

Hand spliced

Hidden tuck rigger sling. More flexible than a mechanical splice, favoured for choking and where the sling must conform to the load.

Cable laid

Multiple ropes laid together. Very flexible with good resistance to kinking, used where a sling gets handled hard.

6-part braided

Six ropes braided into a flat, wide body. Excellent flexibility and a broad bearing surface on the load.

8-part braided

Eight ropes braided, for the heaviest flexible slings. Spreads load over the widest surface of any wire rope sling.

Endless grommet

A continuous loop with no eyes, specified by circumferential length. Wear can be rotated around the body.

Capacity

Rated capacities, published

Working load limits in tons, to ASME B30.9, for Flemish-rolled eye slings with IWRC core and EIPS strength. Basket figures assume a D/d ratio of 25:1 — a smaller pin reduces them.

Before you rig

Wire rope tells you it's failing — if you look

Broken wires, birdcaging, and core protrusion all show before a sling lets go. OSHA 1910.184 and ASME B30.9 require documented inspection by a competent person.

  • Remove from service on broken wires, kinks, birdcaging, or core protrusion
  • No tag, no lift — a sling without a legible tag is out of service
  • Basket capacity depends on D/d — a small pin cuts it sharply
  • Never let a sling bend over a sharp edge without protection
  • A 4 leg wire rope sling is rated above a 3 leg, unlike chain
  • We re-terminate and re-certify damaged assemblies rather than scrapping them

Need something bigger, or built to a print?

Shovel cable, dragline rope, sockets poured and swaged, assemblies to 2 inch and beyond. Bring us a print, a sample, or just the problem.
