Abstract
The present invention relates to a safe operation-stop method for an escalator for safely operating and stopping an escalator that senses an abnormal speed of the escalator so as to prevent passengers from falling. A safe operation-stop method for an escalator is provided, the method including sensing an abnormal speed of the escalator and stopping the escalator before it is reversely rotated, and being capable of reliable braking when an abnormal speed of the escalator occurs, thereby preventing passengers from falling by adjusting the inertial stopping distance when braking.
