1. A civil engineering underground equipment comprising:
at least one work element for groundwork,
at least two actuation units,
at least one measuring device including sensor elements for determining at least one current actuation parameter for each actuation unit, and
a controller, including a database, which is designed for controlling the actuation units,
wherein the controller is connected to the measuring devices, in order to prevent a tipping of the civil engineering underground equipment, and is designed to limit a further actuation of this actuation unit or to display to an operator that the limit actuation parameter has been reached and/or the limit actuation parameter, on the basis of previously calculated limit actuation parameters for the actuation units which define exactly one permissible operating range, when a limit actuation parameter has been reached,
wherein
at least two different individual operating ranges are stored in the controller, wherein each individual operating range comprises a different set of limit actuation parameters for the actuation units,
the controller is designed to determine a combined permissible operating range, by combining the plurality of permissible independent operating ranges, which combined range replaces the exactly one permissible operating range, and
the controller is designed to determine a current value of at least one actuation parameter, during operation of the civil engineering equipment, and, in the event of an associated limit actuation parameter of at least one of the permissible individual operating ranges being exceeded, to no longer take account of said individual operating range with the maximum limit actuation parameters thereof, when determining the combined permissible operating range, and to restrict the combined permissible operating range.
