In this equipment for approach area monitoring for escalators (1) for the control of the drive, light sensors (12) are arranged in the handrail entry caps (11) of the balustrades (3). Each light sensor (12) consists of an emitter (15) and a receiver (16) and operates with, for example, infrared beams. The light sensors (12) monitor the access to the escalator (1) in a specific region (13) in front of the entry to the escalator (1), for example the region of the threshold plate (14). On stepping into the monitoring region (13) of a light sensor (12) the beams emitted by the sensor (15) are reflected by the person or object and picked up by the associated receiver (16) and the drive switched on.
