1. A device for monitoring for bearing capacity failure for a mobile work machine,
wherein the work machine has a number of stabilizers,
wherein each stabilizer has a support foot with a support foot plate, wherein in a supported state of the mobile work machine, at least one support foot plate is arranged on an underlying surface surrounding the work machine or is arranged on a baseplate,
wherein the device for monitoring for bearing capacity failure comprises:
a number of sensors for sensing a change in position in the form of tilting, inclination or rotation about one or more axes of rotation of at least one support foot plate and/or at least one baseplate; and
an evaluation unit which has a data connection to the number of sensors and which is configured to detect bearing capacity failure on the basis of a change in position, sensed by way of the number of sensors, of the at least one support foot plate and/or the at least one baseplate in a supported state.
