Abstract
The present invention discloses and teaches method and apparatus for the detection of a disengaged, moving, handrail on a people moving walkway particularly an escalator. By the present invention a proximity sensor is positioned beneath the handrail for detection of a handrail that has become disengaged from its underlying guide rail. Upon detection of a disengaged handrail, the proximity sensor sends an electrical signal to a controller which stops the escalator or walkway.
