  • Patent number: 6997641
    Abstract: A road milling machine has a driver's cab equipped with a floor plate and a steering gear mounted on the chassis of the road milling machine. The steering gear includes a console, on which a steering wheel is positioned. One end the console is fastened laterally to the chassis, while the other end of the console is not attached to anything. The console extends over the floor plate, forming an opening between the floor plate and the console on a side. Since this opening is below the console, it is possible for the operator to observe the road surface without having to lean to the side, as is necessary with conventional road milling machines, in which the side of the chassis on which the console is positioned blocks the view.
