What is a common cause of elevator door binding?

A common cause of elevator door binding is misalignment or obstruction. Over time, various factors can lead to the misalignment of elevator doors, such as wear and tear on the door tracks, improper installation, or settling of the building structure. When doors are misaligned, they may not open and close smoothly, causing them to bind against the frames or other components when attempting to operate.

Additionally, obstructions—such as debris, loose hardware, or even accumulation of dirt—can interfere with the normal operation of the doors, leading to further binding issues. Recognizing that misalignment and obstructions can block the proper movement of elevator doors is crucial for maintaining safe and efficient elevator operation, as it allows for timely interventions to correct issues before they escalate into more severe problems.
