During routine inspections, what is the key factor to watch for in wire rope integrity?

Worn ends
Corrosion
Broken wires
Color changes

The correct answer is: Broken wires

When evaluating wire rope integrity during routine inspections, broken wires represent a critical concern because they can significantly compromise the strength and safety of the rope. The presence of broken wires indicates potential fatigue or failure in the wire rope, which could lead to catastrophic events if not addressed promptly. The function of the wire rope is to bear loads and resist tension, and broken strands can drastically diminish its load-bearing capacity, raising the risk of accidents. While other factors such as worn ends, corrosion, and color changes can also indicate deterioration, broken wires are a more immediate warning sign that the wire rope may no longer be safe for use. These broken wires can propagate and lead to a greater number of failures if the rope is subjected to continued stress. Therefore, it is critical to inspect wire rope meticulously for any signs of broken wires, as addressing this issue can prevent accidents and ensure the safety of operations.
