Integrity of Large Steel Wire Ropes

Aspec Engineering Integrity of Large Steel Wire Ropes

Steel wire rope forms an important part of many machines and structures. The mechanical properties of a steel wire rope result from the individual wires and their arrangement or construction. Unlike most other metallic components, rope wires are stressed alternately in tension, compression, torsion, and shear. The wires and strands are designed to slide in relation to each other, distributing the complicated applied stresses more effectively. Therefore, wire ropes require prudent inspection, maintenance, lubrication, and periodic replacement.

This article provides general information on steel wire ropes, guidance on their care and maintenance and the process of determining the limit of degradation for discard of wire ropes.
