Abstract
The application relates to a handrail-drive system of an escalator. The handrail-drive system includes a handrail drive with drive elements and a belt-form handrail which can be moved in a circulatory manner. The handrail is delimited by an outer contour configured as a gripping surface and by an inner contour which leaves a cavity free in the handrail. The driving force is transmitted from the drive elements to the handrail on two mutually opposite side surfaces of the inner contour, wherein a complementary configuration of the side surfaces makes it possible for all the other forces which are caused by the transmission of the driving force and act between the side surfaces to compensate for one another.
