Abstract (en)
[origin: WO2022063595A1] The invention relates to a handrail tension monitoring device (41) for a passenger transport system (1) designed as a moving walkway or escalator. The handrail tension monitoring device (41) has at least one distance sensor (34) and a signal processing unit (47). The measurement signals (M) recorded by the distance sensor (34) can be processed and evaluated in the signal processing unit (47). The oscillation frequency (f) of a scanned handrail (15) of the passenger transport system (1) can be determined in the signal processing unit (47) from the signal curve (MV) of the measurement signals (M), and the frequency can be compared with at least one lower threshold value (US) and/or upper threshold value (OS), an alarm signal (Z) being generated when the lower threshold value (US) is fallen below, and a warning signal (W) being generated when the upper threshold value (OS) is exceeded.
