16 ABSTRACT OF THE DISCLOSURE An escalator having a drive unit mounted in a supporting truss via a deflection beam. Load forces developed in the drive unit are transmitted from the drive unit to the ends of the deflection beam via elongated mounting base members which are not subjected to bending moments by the forces. The midpoint of a deflection beam is attached to the truss. Positioning devices adjustably orient the drive unit in the truss, and the midpoint connection of the drive unit to the truss adjustably selects the position of the drive unit along the longitud- inal axis of the truss.
