Abstract
This paper describes an investigation of fatigue resistance in different steel wire rope constructions used in Norwegian cable logging operations. Test results indicate the following:
- A clear difference in fatigue resistance between ropes (approximately 50% decreased endurance for the compacted rope of highest density).
- Differences in rope wear for varying angles of deflection.
- A correlation between the number of visible broken wires and remaining strength in the rope.
