Abstract

A handrail with handrail elements is moved past a sensor support with at least one sensor. Each handrail element has, for example, a collar, which extends into the adjacent handrail element. The handrail elements, which are pivotably fastened to a second transport chain, can move relative to the adjacent handrail elements without a gap then arising between two adjacent handrail elements. Merely a segment groove with such a small depth that fingers are not caught arises between two adjacent handrail elements. The sensor can recognize each segment groove as well as defective handrail elements. Operating magnitudes such as speed, acceleration and deceleration of the handrail are ascertainable and/or risk-laden operating states are recognizable by means of the sensor signal.
