DEVICE FOR SUPERVISING THE ACCESS ZONE OF ELEVATORS AND MOVING WALKS WITH HIGH-FREQUENCY SENSORS

摘要

An escalator (1) has electromagnetic wave sensitive sensors (12) that are arranged within the handrail deflection region of a balustrade pedestal (3), and having predetermined wavelength longer than 100 micrometers. The sensor monitors the entrance plate (14) of an escalator in order to switch-on an escalator driver before entry of passenger.
