Which safety feature activates by a speed governor or suspension failure?

• A. Safety Mechanism
• B. Angle of Inclination
• C. Closing Speed
• D. Winding Drums

Answer: (A)

When the speed governor detects the escalator is moving too fast or a suspension rope fails, the safety mechanism is triggered. Its job is to stop the escalator by engaging the drive brake or safety gear, preventing runaway movement or a dangerous drop of the steps. The other choices aren’t automatic responses to governor overspeed or suspension faults: the angle of inclination is just the escalator’s tilt and doesn’t engage due to a fault; closing speed relates to how quickly a mechanism like a gate or door operates, not a fault response; winding drums are part of the drive system, not the safety interlock that activates during those fault conditions.
