A travelator, moving ramp or escalator for transporting people, comprises a people mover; a balustrade extending alongside the people mover throughout its length. The balustrade comprises a handrail belt formed as an endless loop and having an upper handhold portion, which the passenger can grasp with a hand for support, a lower return portion, and a turn-around portion between the handhold portion and the return portion. The balustrade frame comprises a turn-around guide at the end of the balustrade to form a turn-around to support and guide the turn-around portion of the handrail belt. The turn-around guide comprises a number of pressure rollers spaced at a distance from each other and arranged in a sequence in the form of a circular arc. In addition, a drive assembly is arranged to move the handrail belt. The drive assembly comprises a drive belt formed as an endless loop and having a contact portion which is in driving contact with the handrail belt over a predetermined length, and a power mechanism for driving the drive belt. The contact portion of the drive belt is passed over the sequence of pressure rollers between the pressure rollers and the turn-around portion of the handrail belt.
