Common Damaged Wire Rope Signs
Recognizing damaged wire rope signs early can prevent accidents and expensive equipment failure.
Birdcaging
Birdcaging occurs when strands separate and form a cage-like appearance. This condition usually results from sudden load release or improper handling.
Kinks
Kinks permanently deform the rope structure and reduce load capacity. A kinked rope should never return to service.
Crushing
Crushing damage occurs when ropes are compressed improperly on drums or under heavy loads.
Core Failure
Internal core damage weakens rope support and causes uneven strand movement.
Corrosion Pitting
Corrosion pitting reduces wire strength and accelerates fatigue cracking.
Abrasion Wear
External wear from friction gradually removes metal from outer wires.
Rope Stretching
Excessive elongation may indicate internal structural damage or overload conditions.
All these damaged wire rope signs require immediate evaluation by qualified personnel.
