An automotive milling machine, for the treatment of road surfaces or ground surfaces includes a chassis comprising front and rear suspension axles with a total of no less than three suspension units with a machine frame supported by the chassis, with lifting columns between the suspension units and the machine frame at no less than two suspension units of a suspension axle, said suspension units being transversely offset from one another in the direction of travel, and with a working drum. The working drum is adjustable to a position for driving in travel mode with the working drum raised and, in the adjusted position of the working drum at a distance from the road surface or ground surface, the lifting columns are suitable for coupling to a spring device.
An automotive milling machine apparatus for the treatment of a road surface or ground surface, comprising:
A method of using a milling machine to treat a road surface or a ground surface, the milling machine including a machine frame, at least three suspension units for supporting the machine on the road surface or ground surface, at least two of the suspension units being transversely offset from each other on a front suspension axis or rear suspension axis, two lifting columns connected between the machine frame and the two transversely offset suspension units, each lifting column including a piston-cylinder unit, the method comprising:
A method of increasing an operating efficiency of a milling machine, the machine including a working drum for working a road surface or a ground surface, the method comprising:
