What causes rouging on wire ropes?

Rouging on wire ropes is primarily caused by friction between the rope components due to a lack of lubricant. When wire ropes are not adequately lubricated, the strands and wires rub against each other during operation, generating heat and wear. This friction can lead to the formation of rust or corrosion, which manifests as rouging—a reddish-brown discoloration that indicates surface degradation.

Using appropriate lubricants reduces this friction, helping to protect the wire ropes from wear and corrosion. Proper lubrication not only minimizes rouging but also extends the overall lifespan of the rope. In contrast, issues such as inadequate cleaning, incorrect materials, or improper installation contribute to other potential problems but do not directly relate to the specific mechanism that causes rouging.
