Abstract
A handrail drive for driving a handrail of a person-transporting device has at least one drive device and at least one counterpressure device. The counterpressure device contains at least one loading device and at least two counterpressure rollers, wherein the handrail can be guided between the drive device and the counterpressure device. The counterpressure rollers load the handrail against the drive device by a pressing force caused by the preloading force of the loading device. At least one flexible pulling element is arranged between the at least one counterpressure roller and the loading device, by which flexible pulling element the preloading force of the loading device can be transferred to the at least one counterpressure roller.
