What stops lift during rapid downward movement?

Explanation:
Escalator safety systems are built to stop motion when speed exceeds a safe limit. During rapid downward movement, an overspeed condition is detected by the overspeed safety sensor, which then triggers the braking or drive shutoff to stop the steps quickly. This device is specifically designed to respond to runaway or too-fast movement to protect riders. The safety governor is a speed-limiting device used in elevators, not the primary stopping mechanism for escalators in this scenario. The rack and pinion is simply part of the drive mechanism, not a safety stop, and talcum powder has no role in stopping movement.
