The drive comprises one or several identical drive units (7) which are arranged distributed at the extent of a main driving gear (6). The drive units (7) can be flanged in longitudinal- or crosswise direction to the drive direction of the escalator at a common main drive gear-box (8). Not required connection apertures (24) at the main gear-box are locked with a cover. The drive is installed at a lower and/or upper end, on one or both sides of the escalator, and comprises one or several identical drive units (7) which are arranged distributed at the extent of a main driving gear (6). The drive units can be flanged in longitudinal- or crosswise direction to the drive direction of the escalator at a common main drive gearbox (8). Not required connection apertures (24) at the main gearbox are locked with a cover. The motors of the drive units are preferably controlled by a common frequency regulator. A control and regulation unit preferably processes input data of different components and function groups to provide control- and regulation data for the frequency regulator. |
