Install the escalator disinfection device at the bottom of the handrail belt at the entrance of the escalator, isolating it from the handrail area that passengers come into contact with, thereby preventing accidents where passengers' fingers could get caught in the escalator disinfection device. Combined with an intelligent control method, a corresponding timed sterilization and disinfection strategy is developed based on the actual operation of the escalator. This ensures the hygiene of the escalator handrail belt, allowing passengers to ride the escalator with greater peace of mind and safety.
