| Severe wear, associated with high tread pressure. Protrusion of fibre main core. | Severe wear in Lang Lay, caused by abrasion or cross-over points on multi-layer coiling application. | Corrosion of severe
degree caused by immersion of rope in chemically treated water. |
 |
 |
 |
| Typical wire fractures
as a result of bending fatigue. |
Wire fractures at the strand, or core interface, as distinct from crown fractures, caused by failure of core support. | Strand core protrusion
as a result of torsional unbalance created by drop ball or other shock
loading application. |
|
|
 |
|
Break up of IWRC
resulting from high stress application. Note nicking of wires in outer
strands.
|
Typical example
of localised wear and deformation created at a previously kinked portion
of rope.
|
Multi strand rope
bird-caged due to torsional unbalance. Typical of build up seen at anchorage
end of multi-fall crane application.
