Wire Rope Slings
A pendant rather than a sling: a length of wire rope with a socket swaged onto each end instead of an eye. The socket is pressed onto the rope under enormous pressure and the termination is worth 100% of the rope’s catalog strength — nothing is given away at the end, which is the whole reason to specify one.
That makes them the standard for crane pendants, boom stops, guy lines and standing rigging — anywhere the assembly is a permanent structural member rather than something thrown over a load. Every one we build is proof tested to twice its working load limit before it leaves.
Features
- 100% termination efficiency
- Sizes available from 1/4” to 1-1/4”
- Proof tested to 2× the working load limit
- 5:1 design factor
- Made in Hatfield, PA
How to order
- Specify wire rope size
- Specify leg length
- Specify end fittings
- Specify termination plane
Length on a pendant is measured from the centre of the pin to the centre of the eye, not end to end. Termination plane matters too: if the two sockets have to line up with each other, say so when you order, because we set it during fabrication and it cannot be adjusted afterwards.
Assembly types
Six standard configurations. Open sockets take a pin, closed sockets take a shackle or a hook — and the two pins either line up with each other or sit at right angles. That last part is the termination plane, and it is set during fabrication, so it has to be specified with the order.

Fabricated in Hatfield and proof tested in house. Tell us the size, the length and the fittings and we will build it; if you would rather tell us the load and the geometry, we will work out the sling.
When to take a sling out of service
Look at a sling before every lift, and have it inspected properly at least once a year — more often if it is working hard. Remove it from service and destroy it if you find any of this:
The rope
- Ten randomly distributed broken wires in one rope lay
- Five broken wires in one strand in one lay
- Wear or scraping of one third the original diameter of an outside wire
- Kinking, crushing, birdcaging or any distortion of the rope structure
- Heat damage — melting, charring, or weld spatter
- Severe corrosion, or pitting you can feel
- A section that has stretched noticeably thinner than the rest
The ends and fittings
- Broken or worn wires at or near an end attachment
- A cracked, deformed or worn end fitting
- A hook opened past the manufacturer’s limit, or twisted
- A missing or unreadable identification tag
- A sling that has been shock loaded
- Any repair not made by a qualified person
This follows ASME B30.9. A sling with no legible tag cannot be used, whatever condition the rope is in — and retagging is not something to do from memory, because the tag has to match what the sling actually is. Bring it to us and we will identify it, test it and tag it, or tell you plainly that it should be replaced. We also inspect on site and cover all of this in rigging training.
