On this escalator (1) which has on each side a balustrade (1.1) with handrail (2) the balustrade (1.1) is held by a balustrade base (1.2). A step-band (1.3) which has steps (1.4) and transports persons abuts at the side against the balustrade base (1.2). A handrail-drive (2.1) drives the handrail (2) , a friction-wheel (3) driving the handrail (2) on the outside (2.2). On the inside (2.3) of the handrail (2), rollers (8) press the handrail (2) against the friction-wheel (3). A friction-wheel (4) arranged on a step chain-wheel (5) drives the friction-wheel (3) by frictional or mechanical engagement.
