Guide to Examination

Mechanical damage due to rope movement over sharp edge projection while under load.

Typical wire fractures as a result of bend fatigue.

Localized wear due to abrasion on supporting structure.

Wire fractures at the strand, or core interface, as distinct from ‘crown’ fractures.

Narrow path of wear resulting in fatigue fractures, caused by working in a grossly oversize groove, or over small support rollers.

Break up of IWRC resulting from high stress application.

Two parallel paths of broken wires indicative of bending through an undersize groove in the sheave.

Looped wires as a result of torsional imbalance and/or shock loading.

Severe wear, associated with high tread pressure.

Typical example of localized wear and deformation.

Severe wear in Langs Lay, caused by abrasion.

Multi strand rope ‘bird caged’ due to torsional imbalance.

Severe corrosion.

Protrusion of rope center resulting from build up of turn.

Internal corrosion while external surface shows little evidence of deterioration.

Substantial wear and severe internal corrosion.
