<p>The invention relates to a hand rail (5) comprising hand rail members (5.1), which is moved past a sensor carrier (11.1) comprising at least one sensor (10). Each hand rail member (5.1) has a collar (5.11) which extends into the adjacent hand rail member (5.1). The hand rail members (5.1) articulated to a second conveyor chain (8) can move relative to the adjacent hand rail members (5.1) without a gap forming between two adjacent hand rail members (5.1). Merely a segment groove (5.12) develops between two adjacent hand rail members (5.1), the depth of said groove being so small that that fingers do not become jammed. The sensor (10) can detect each segment groove (5.12) and defective hand rail members (5.1). By means of the sensor signal, it is possible to determine operating variables such as speed, acceleration, deceleration of the hand rail (5) and/or detect dangerous operating states.</p> |
