What's the Difference Between Regular Lay and Lang Lay?

When discussing the physical properties of wire rope, people often focus on the material, strength, and size specifications above all else. While these details are essential to understand how a product will survive in the field, they are not the only factors that drive cable performance. In fact, the lay direction of a cable has as much impact on its functionality as any of the other aforementioned characteristics, because it determines how much[…]

What’s the Difference Between Elastic and Structural Stretch?

Structural Structural stretch is caused by the adjustment of wires and strands within a wire rope, along with compression of the core and lengthening of the lay. As the cable moves and works, its components shift slightly and settle. Many varying qualities contribute to the structural stretch of a wire rope, including its core size, construction, and lay lengths. If the rope is passed over a sheave, the amount of bending it is subjected to will[…]
