  • Device for monitoring for bearing capacity failure and system
    Patent number: 11981550
    Abstract: A device monitors for bearing capacity failure of a mobile work machine. The work machine has a number of stabilisers. Each stabiliser has a support foot having a support foot plate. When the mobile work machine is in a supported state, the support foot plate of at least one support foot is arranged on a base surface surrounding the work machine or on a base plate. The device for bearing capacity failure monitoring has a number of sensors for sensing a change in position of at least one support foot plate and/or at least one base plate. The device has an evaluation unit, which has a data connection to the number of sensors and is designed to detect a bearing capacity failure on the basis of a change in position of the at least one support foot plate and/or the at least one base plate that has been sensed by means of the number of sensors.
