ABSTRACT:
An escalator has a step-band with steps for the transport of persons. The step-band is bounded on its sides by a balustrade held by a balustrade base. A handrail-drive drives the handrails, and has friction-wheels driving the handrails on the outside of the handrails. Rollers press upon the insides of the handrails, pressing the handrail against the friction-wheel. At least one further friction-wheel arranged on a step chain-wheel drives the friction-wheel through frictional or mechanical engagement.
