Wire Rope Testing: Don’t Trust it, Prove it.

Wire ropes carry huge loads. If one cable fails, the fallout can be severe: dropped cargo, damaged equipment, and people at risk. The trouble is, the worst damage often hides inside the rope. So, a simple visual inspection just isn’t enough.  

Why looking isn’t enough 

Looking doesn’t always give you the full picture. Grease can hide rust and wires can break in the core first… you might not see anything until it’s too late. That being said, visual checks are still important. But you also need a way to look through the rope and measure what’s going on inside. 

How modern rope scanning helps 

A wire-rope scanner is a clamp that goes around the rope. As the rope runs through it, magnets and sensors pick up two things: 

• Sharp signals from broken wires 

• Slow changes that point to overall metal loss (wear or corrosion) 

You see the results live on a screen and can save them for a later date. Meaning, you can compare today’s test with last month’s and make decisions based on evidence, not guesswork. 

How often should you test wire ropes? 

Rules and duty cycles are all different – but as a starting point, aim for at least once a year. Test more often if the rope works hard, operates in harsh conditions (salt, humidity, dirt), or lifts critical loads. Always test after any incident or overload. 

When things go wrong 

This isn’t theoretical. In 2022, a cargo ship crane rope snapped during offload in Houston, dropping a wind turbine component and causing multi-million-dollar damage. Investigators later found corrosion and wear that wasn’t caught by visual checks. The lesson learnt: if you rely on wire ropes, rely on proof. 

Where wire rope scanning adds value 

Anywhere a rope failure would be costly or dangerous: 

• Ports and logistics (ship-to-shore, RTGs, overhead cranes) 

• Mining (hoists, draglines, shovels) 

• Offshore and marine (rig cranes, winches) 

• Construction and heavy industry (tower and gantry cranes) 

• Cable transport and amusement rides 

Nexxis Wire Rope Scanners

At Nexxis, we stock a range of wire-rope testing scanners sized for different rope diameters and duties. You can rent, lease, or buy. Every unit gives you live results and an exportable dataset, so you can trend rope health over time and prove decisions to your team or auditors. 

The pay-off 

• Safety: spot hidden damage before it becomes a failure 

• Uptime: test in place, no need to strip the system 

• Cost control: replace on condition, not on hunches or fixed intervals 

• Traceability: keep a digital record of every test 

Don’t wait for a break to tell you there was a problem.
