Wire rope plays a critical role in your rigging operation, but like all equipment, it has a lifespan. To prevent potential accidents, wire rope must be replaced periodically. But what are the signs it’s time to do so?
Visual Inspection
Simply looking at your wire rope can tell you a lot about its condition. Keep an eye out for broken strands or individual wires, excessive wear from friction or bending, signs of corrosion such as rust and unusual kinking patterns.
A good rule of thumb is that if your wire rope is about to reach its minimum recommended diameter, it’s time to replace it.
Wire Rope Fatigue
Wire rope undergoes constant stress and fatigue during rigging operations. This stress can reduce the load-carrying capacity over time.
If your wire rope has been subjected to excessive loads during its time in use or has been repeatedly bent, twisted or stretched, it may be at its limit. If you’re not sure, consult the maximum service life recommended by the manufacturer.
Loss of Lubrication
Lubricant helps reduce friction as individual wires in your rope move over each other. In other words, insufficient lubrication increases friction, accelerates wear and heightens the risk of corrosion.
Keep an eye out for dry wire rope surfaces, as these may indicate a lack of lubrication. Lubricate per the manufacturer’s suggestions. If your rope has become less lubricated due to damage or wear, it is likely time for a replacement.
How Often Should I Inspect My Wire Rope?
OSHA and ASME advise inspecting your wire rope frequently for wear and tear. Set a regular inspection schedule, such as daily before each shift or after every installation and repair. Remember that it is always better to be overly-cautious than not cautious enough.
If you are not diligent about replacing your rope, you could receive a finding from inspection services for non-compliance. Start performing regular inspections yourself so that you don’t end up in trouble later.
