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.
