Title Wire ropes: Experience gained from a damage claim
Original title Drahtseile: Erfahrungen aus einem Schadensfall [in German]
Bibliographic information Sep. 1995, Vol.45, No.9, p.647-649. Illus. 5 ref.
Abstract The wire rope of a telescopic jib crane ruptured after it had been in use for only 2 months. A force of only 4kN acted on the rope at the time of rupture. Strength tests were performed and the guiding tracks of the wire rope were inspected to determine the cause. An untwining of the outer strands of the wire rope with all weight being borne by the inner strands is thought likely to have caused the sudden and premature rupture.
