When applying wire rope clips properly, how much is the strength of the wire rope typically reduced?

When properly applying wire rope clips, the strength of the wire rope is typically reduced by about 20%. This reduction accounts for the potential loss of strength due to the way wire rope clips create a connection point. When the clips are applied, they secure the loose end of the wire rope back onto itself, forming a loop. However, this connection does not utilize the full strength of the rope because of the bend and the load distribution created by the clips.

The specific reduction in strength is due to the fiber crushing and the bending stress introduced at the site of the clips. Over time, and under load, this area becomes the most susceptible to failure if not managed properly. Therefore, understanding that a strength reduction of approximately 20% is standard helps in various applications where safety and the maximum load capacity must be calculated. This knowledge is critical for ensuring that the safe working load (SWL) is not exceeded in practical applications involving lifting or securing loads with wire rope.
