Abstract
A handrail drive for driving a handrail of a transportation system has at least one drive device and at least one counterpressure device. The counterpressure device contains at least one taughtening spring and at least one counterpressure-roller. Between the drive device and the at-least one counterpressure-roller, the handrail is arranged approximately in a linear travel direction and, with a press-on force which is caused by the taughtening spring, is pressed by the at-least one counterpressure-roller against the drive device. The handrail drive has a mechanical redirection device, by which the spring-force of the taughtening spring can be redirected into the press-on force of the at-least one counterpressure-roller.
