What is the main cause of elevator door failure?

The primary reason for elevator door failure is due to the wear and tear of components or a lack of maintenance. Elevator doors are mechanical systems that undergo frequent use, leading to the natural degradation of parts over time. Components such as rollers, tracks, and door operators can wear down, resulting in misalignment or operational failures. Regular maintenance is essential to ensure all parts are functioning correctly and to replace any worn-out components before they lead to more significant issues.

Neglecting maintenance can exacerbate these problems, as minor wear can progress into failures that affect the safety and functionality of the elevator system. Thus, ongoing inspections and maintenance routines are crucial for prolonging the lifespan of elevator doors and preventing unexpected failures.
