Zusammenfassung:A re-entry housing is provided through which the handrail pass at the commencement of a handrail return path of travel. A sensor is disposed at the re-entry housing for detecting foreign objects on the handrail, the sensor being operable to generate an obstruction signal when an object is detected on the handrail. A drive includes a tension unit contacting the handrail for applying a driving force to the handrail to move it along its path of travel. The tension unit is released to disable the drive from applying the driving force to the handrail upon generation of the obstruction signal. The handrail will stop moving when a foreign object is detected on the handrail.
