Not maintaining proper lubrication on wire ropes significantly increases wear and the risk of failure. Lubrication is essential for reducing friction between the strands of wire, which helps prevent abrasion and internal wear. When wire ropes are not adequately lubricated, they become more susceptible to corrosion, debris accumulation, and strand fatigue. Over time, this deterioration can lead to breakage, compromising the safety and performance of the crane.

The wear can manifest physically as flattened strands or broken wires, directly impacting the lifting capabilities and overall structural integrity of the wire rope. As a result, not only does this increase the likelihood of a catastrophic failure, but it can also lead to costly downtimes for repairs and replacements.

In comparison, flexibility and strength are attributes that can be negatively affected by insufficient lubrication, making the proposition of increased flexibility or enhanced strength misleading. Likewise, the idea that there would be no significant effect negates the critical importance of proper maintenance practices in ensuring the safety and functionality of lifting equipment.
