A first front pair and second rear pair of stabilizer devices associated to the frame of an operating machine, defining, in operative position, a resting base, equal in length to the longitudinal distance between the pairs and equal in width to the transversal distance between the resting feet of each of the latter. Each stabilizer device includes a first and an interconnected second module, one of which is provided with linear elongation means and the other with compass elongation means, the linear and compass elongation means being aimed at being operated in phase relation to define a retracted inactive position, in which the corresponding resting foot is raised from the ground, and a withdrawn operation position, in which said resting foot contacts the ground, at a predetermined distance from the longitudinal midline, such that in this resting base the width distance is at least near to that of the relative length. |
