1. A stabilized machine that comprises;
a self-propelled base frame movably supported by a motorized ground support arrangement and provided with an upper support plane;
a motorized turntable supported on top of the support plane of the base frame and rotatable with respect to an axis of rotation orthogonal to the support plane;
an elevating arm, one first end of which is articulated to the turntable and one second opposed free end of which is adapted to be fixed to an operating arrangement;
a plurality of stabilizers each of which is rotatably associated with the base frame about an axis of oscillation lying on a plane orthogonal to the axis of rotation of the turntable, alternatively between a working position, in which it is supported on the ground in addition to or as an alternative to the support arrangement, and a rest position, in which it is raised off the ground;
a control system comprising a plurality of sensors, one for each of the stabilizers, wherein each sensor is configured to detect a first parameter indicative of an inclination of the respective stabilizer about its axis of rotation, and an electronic control unit operatively coupled to the plurality of sensors.
