Rope Injury Cause

Safe Works

1	Mechanical damage due to rope movement over sharp edge projection while under load.	8	Typical wire fractures as a result of bend fatigue.
2	Localized wear due to abrasion on supporting structure.	9	Wire fractures at the strand, or core interface, as distinct from “crown” ractures.
3	Narrow path of wear resulting in fatigue fractures, caused by working in a grossly oversize groove, or over small support rollers.	10	Break up of IIWRC resulting from high stress application.
4	Two parallel paths of broken wires indicative of bending through an undersize groove in the sheave.	11	Looped wires as atresult of torsional imbalance and/or shock loading.
5	Severe wear, associated with high tread pressure.	12	Typical example of localized wear and deformation.
6	Severe wear in Langs Lay, caused by abrasion.	13	Multi strand rope “bird caged” due to torsional imbalance.
7	Severe corrosion.	14	Protrusion of rope center resulting from build up of turn.
