In this equipment for monitoring the space in front of escalators (1) for the control of the drive, sensors (12) are arranged in handrail inlet caps (11) of the balustrades (3). Each sensor consists of a transmitter (15) and a receiver (16) and operates with high-frequency waves. The sensors monitor the access to the escalator in a specific region (13) in front of the entry to the escalator, for example the region of the entrance plate (14). On walking into the monitoring region of a sensor the high-frequency waves emitted by the transmitter are reflected by the person or object and picked up by the associated receiver and the drive switched on.
