ABSTRACT:
The handrail of an escalator is continuously monitored for movement by a sensor assembly. In the event that the handrail stops moving, the escalator steps are stopped so as to provide a safe environment for passengers on the escalator. The system can also be used with moving walkways equipped with moving handrails.
