Abstract

A road milling machine having a milling roller with a plurality of chisels. A signal receiving unit is assigned to a machine component which is directly or indirectly involved in the milling process or to another machine component. The signal receiving unit detects an operating condition of the machine component and is connected to a signal emitting unit. An optical detecting device may be assigned to the road milling machine, whereby operations are made easier and the milling pattern is optimized.
