Abstract
The application relates to a passenger transport apparatus comprising at least one drive sprocket for driving and deflecting a conveyor belt, and at least one detecting apparatus for detecting the rotational speed of the drive sprocket. Slot-shaped recesses are arranged on at least one annular side surface of the drive sprocket, wherein the longitudinal extension of the slot-shaped recesses extends in the radial direction with respect to the rotational center of the drive sprocket over the annular side surface. The detecting apparatus makes it possible to generate a signal that represents the rotational speed of the drive sprocket, by means of scanning of the slot-shaped recesses—which can move relative to the detecting apparatus—and the elevations present between the slot-shaped recesses.
