In this escalator the step belt (4) consists of motor-driven steps (3) and free-running steps (3.1). A drive frame (15) connected with a step frame (13) serves as support for a drive unit of the motor-driven step (3), wherein the drive unit consists of a motor (17), a transmission and a brake (19). A friction wheel (20) which transmits the drive power to a travel track (21) is arranged at the transmission output, wherein a counter- pressure roller arranged in fixed position at the drive frame (15) laterally guides the step (3).

Sur cet escalier mécanique, la chaîne de marches (4) consiste en marches entraînées par moteur (3) et en marches libres (3.1).
