Some of the More Common Types of Wire Fractures Can Include:
|
|
| 1 |
Mechanical damage due to rope movement over sharp edge projection whilst under load. |
|
 |
|
| 2 |
Localised wear due to abrasion on supporting structure. |
|
 |
|
|
| 3 |
Narrow path of wear resulting in fatigue fractures, caused by working in a grossly oversize groove, or over small support rollers. |
|
 |
|
| 4 |
Two parallel paths of broken wires indicative of bending through an undersize groove in the sheave. |
|
 |
|
|
| 5 |
Severe wear, associated with high tread pressure. |
|
 |
|
| 6 |
Severe wear in Langs Lay, caused by abrasion. |
|
 |
|
|
| 7 |
Severe corrosion. |
|
 |
|
| 8 |
Internal corrosion whilst external surface shows little evidence of deterioration. |
|
 |
|
|
| 9 |
Typical wire fractures as a result of bend fatigue. |
|
 |
|
| 10 |
Wire fractures at the strand, or core interface, as distinct from crown fractures. |
|
 |
|
|
| 11 |
Break up of IWRC resulting from high stress application. |
|
 |
|
| 12 |
Looped wires as a result of torsional imbalance and/or shock loading. |
|
 |
|
|
| 13 |
Typical example of localised wear and deformation. |
|
 |
|
| 14 |
Multi strand rope bird caged due to torsional imbalance. |
|
 |
|
|
| 15 |
Protrusion of rope centre resulting from build up of turn. |
|
 |
|
| 16 |
Substantial wear and severe internal corrosion. |
