In this handrail-drive a drive-wheel chain-wheel (4.9) is connected by means of an axle (4.16) to a drive-wheel (4.15) which carries a drive-wheel tire (4.1), the axle (4.16) being held rotatably by bearings (4.17). The drive-wheel tire (4.1) which is filled with a gas, for example compressed air, is pulled over a dismountable wheel-rim. (4.18) which is arranged on the axle (4.16). The drive-wheel tire (4.1) adapts to the shape of the handrail. Due to the springing properties or air-cushion properties of the drive-wheel tire (4.1) and the greater contact surface which results therefrom, the handrail is deformed only slightly or insignificantly.
