What safety mechanisms must be inspected regularly on elevator doors?

The safety mechanisms that must be inspected regularly on elevator doors include interlocks, sensors, and edges because these components play crucial roles in ensuring the safe operation of the elevator system. Interlocks are designed to prevent the elevator from moving when the doors are open, effectively reducing the risk of accidents during boarding and disembarking. Sensors, which can detect the presence of objects or people in the doorway, also contribute to safety by ensuring that doors do not close on passengers or obstructed objects. Edges, often equipped with protective mechanisms such as safety edges or beams, help to further prevent injuries by reversing door motion if they encounter resistance.

Regular inspection of these elements is essential for maintaining the overall safety of the elevator system, as they directly impact how the elevator door operates in relation to passenger safety. Ensuring these parts are functioning correctly helps mitigate risks associated with elevator door operations, contributing to a safer experience for users.
