b) Breakage of wires on the end connection
Broken wires on or near the end connection are due to major localised stress and are possibly
due to an incorrect mounting of the anchoring sockets.
Identify the exact cause of the damage and possibly mount the anchoring sockets more
accurately after shortening the rope provided it is long enough for future uses.

c) Broken strands
If a strand breaks, replace the wire rope.
d) Elasticity decrease
In some cases the rope can undergo a considerable loss of elasticity that makes future uses
dangerous. Evaluation of elasticity decrease is difficult and requires the advice of an expert.
This defect is usually associated to the following phenomena:
•
Reduction of the rope diameter.
•
Rope elongation.
•
Lack of space between the single wires and the strands caused by the mutual
compression of the different elements.
•
Presence of a fine dark dust inside the strands.
•
No breakage is visible but the rope is much stiffer to handle and has a higher diameter
reduction than the one caused by the deterioration of single wires. Such a condition can
lead to a sudden break of the rope under dynamic load and justifies an immediate
replacement.
