Examining the Nuances of Cable Stretch
Stretch in wire rope is variable based on multiple factors. Both constructional stretch and elastic stretch are apparent under load applied to the cable. In this white paper we’ll explore the two types of stretch, their differences, and if they are a concern for your system design.
Two types of stretch occur in wire rope:
- Constructional Stretch – Occurs when a load is applied to wire rope and as a result the wire rope has slightly decreased in diameter and increased in length.
- Elastic Stretch – The individual wires of a cable construction are physically elongated under tension, with the total stretch proportionate to the load applied.
Constructional Stretch vs. Elastic Stretch: Can It Be Removed?
Designers must consider if the inherent stretching nature of wire rope under tension is of concern for their specific application. In the majority of applications, constructional stretch and elastic stretch are not an issue.
