A method is provided for measuring the milling depth of a road milling machine, the machine being operative to mill a ground surface with a milling roller lowered to a milling depth to create a milling track, the machine including at least one side plate located to at least one side of the milling roller to engage an untreated ground surface, and the machine including a stripping plate operative to be lowered onto the milling track generated by the milling roller. The method includes measuring the milling depth of the milling track, the measuring including detecting a measurement value of a ground engaging sensor engaging the milling track.

In an automotive construction machine, with a machine frame () with preferably vertically arranged lateral outer walls (), a milling drum () mounted in the machine frame () for working a ground surface or traffic surface (), and with an operator's platform (), it is provided that the operator's platform () is moveable on the machine frame () transversely to the direction of travel, and is moveable outwards beyond the lateral outer walls () of the machine frame (), that the machine frame () is provided with a guide () for the operator's platform () acting transversely to the direction of travel, and that the guide () projects laterally either not at all or just slightly beyond the outer walls ().

Automotive construction machine

A construction machine for the treatment of ground surfaces includes a machine frame and a work drum supported from the machine frame and including exchangeable tools fastened to the work drum. A drive line includes a work motor and a transmission connecting the work motor to the work drum. The transmission includes a belt drive and a reduction gear. An auxiliary drive is mounted at a location on the construction machine and includes an auxiliary drive motor. The auxiliary drive has a first configuration in which the auxiliary drive motor is coupled to the work drum via at least a portion of the transmission to rotate the work drum. The auxiliary drive has a second configuration in which the auxiliary drive remains mounted at the location on the construction machine and the work drum can be rotated by the work motor.

Auxiliary drive

A construction machine for the treatment of ground surfaces includes a machine frame, a drive motor, a work drum supported from the machine frame and including exchangeable tools fastened to the work drum, a belt drive and an auxiliary drive. The belt drive includes a motor-side pulley connected to the drive motor, a drum-side pulley connected to the work drum, and at least one drive belt connecting the motor-side pulley to the drum-side pulley. The auxiliary drive may be permanently coupled to the belt drive, or the auxiliary drive may include an adjustment mechanism for moving the auxiliary drive between a coupled and an uncoupled position.
