ABSTRACT:
An escalator or moving walkway has a step or plate belt with motor-driven steps or plates and free-running steps or plates. A drive frame connected with a frame serves as support for a drive unit of a motor-driven step or plate. The drive unit includes a motor, a transmission and a brake. A friction wheel, which transmits drive power to a travel track, is arranged at the transmission output, while a counter-pressure roller arranged in a fixed position on the drive frame laterally guides the step.
