What is the most common cause of rope failure?

Lack of lubrication is indeed a significant factor contributing to rope failure in elevators. Proper lubrication is essential for ensuring that the ropes can move smoothly over pulleys and other surfaces without excessive friction. When the ropes are not adequately lubricated, they experience increased wear and tear. This friction can lead to deterioration of the rope fibers over time, resulting in premature failure. Regular inspection and maintenance that includes lubrication help extend the life of the rope and ensure safe elevator operation.

Other factors can contribute to rope failure, such as overloading, exposure to harsh weather, and incorrect installation, but the absence of lubrication directly impacts the efficiency and longevity of the ropes, making it a primary cause in many cases.
