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.

Mobile operating machine, provided with at least a work device (11) supported by a movement turret (14), at least a pair of stabilizing front legs (12a, 12b) and at least a pair of stabilizing back legs (13a, 13b); the mobile operating machine also comprises a support structure (18) provided with at least a pair of box-like elements (19a, 19b) configured to house the stabilizing front legs (12a, 12b) or back legs, and at least a positioning seating (20) of the movement turret (14) made in a crossing zone (Z) of the box-like elements (19a, 19b); each box-like element (19a, 19b) is provided with a first end (23a, 23b) that is open and through which a respective stabilizing front leg (12a, 12b), or back leg, is slidingly mobile and a second end (25a, 25b), opposite the first end (23a, 23b) and in correspondence with which a respective stabilizing back leg (13a, 13b), or front leg, is pivoted, so as to rotate around a corresponding axis of rotation (R1, R2).

A support force measurement apparatus for determining a support force on a support element of a support structure of a movable working machine. The measurement apparatus has at least one measurement element and a support leg. The measurement element is connected to a deformation body capable of being deformed with an effect of the support force, so as to form a sensor and send a signal proportional to the support force. The support leg has the sensor and is movably connected to the support element. The support element comprises a cable connection, and the cable connection is constructed in a manner of guiding electrical energy and is used for sending the signal proportional to the support force to an analysis apparatus in a machine. The support element in the support leg and the sensor are provided with electromagnetic interfaces.
