The invention relates to civil engineering underground equipment comprising at least one work element for ground work, at least two actuation units, at least one measuring device for determining at least one current actuation parameter for each actuation unit, and a controller which is designed for controlling the actuation units, wherein the controller is connected to the measuring devices and, in order to prevent a tipping of the civil engineering underground equipment, is designed to limit a further actuation of the 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 of at least one actuation unit is reached. It is intended for at least two different individual operating ranges to be stored in the controller, wherein each individual operating range comprises a different set of limit actuation parameters for the actuation units, and for the controller to be able to determine a combined permissible operating range.

Civil engineering underground equipment and method for operating civil engineering underground equipment

The invention relates to a safety means for a construction machine having a carrier unit and an actuation unit, which is adjustable with respect to the carrier unit, comprising at least one detecting means for detecting the current position of the actuation unit relative to the carrier unit, an indication means with which the current position of the actuation unit relative to the carrier unit can be indicated, and an evaluation unit, by means of which, depending on at least one input value, at least one adjustment range of the actuation unit can be determined, in which the actuation unit is adjustable at a given safety against tilting of the construction machine, whereby the adjustment range can be indicated together with the current position of the actuation unit by means of the indication means.

Safety means for a construction machine

The invention relates to a construction machine having a carrier unit, an actuation unit, which is adjustable with respect to the carrier unit, at least one detecting means for detecting status data of the construction machine, and a computer unit, by means of which, based on the detected status data, at least one adjustment range of the actuation unit can be determined, in which the actuation unit is adjustable at a given safety against tilting of the construction machine. The invention also relates to a method for operating a construction machine of such type.
