CIVIL ENGINEERING MACHINE AND METHOD FOR OPERATING A CIVIL ENGINEERING MACHINE

The invention relates to a civil engineering machine, in particular a drilling rig, having a mobile carrier device, a mast or jib arm which is arranged on the carrier device, a civil engineering tool which is arranged adjustably on the mast or the jib arm in order to carry out a civil engineering operation, at least one display device, in particular a monitor, and a control unit which is configured to control components of the civil engineering machine and to detect operating states and, depending on detected operating data, to generate an at least schematic representation of at least one part of the civil engineering machine and to display it by means of the at least one display device, wherein a change in position of the civil engineering tool and/or at least one component of the civil engineering machine is displayed in the at least schematic representation of the one display device. According to the invention it is provided that the control unit is configured to automatically change a display scale and/or a type of representation of the at least schematic representation of the display device in the event of certain changes in position of the civil engineering tool and/or of at least one component of the civil engineering machine.
