Mobile machine comprising a stabilizing device

In a mobile machine comprising a frame, a beam mounted on the frame, and a stabilizing device, the stabilizing device comprising at least two arms, means pivotally mounting each arm on the beam for pivotal movement about a pin and each arm being coupled to a first member for adjusting its pivoting with respect to said beam and supporting a sole plate for abutment on the ground, the pivot pins of the two arms with respect to the beam being parallel, means mounting the beam to pivot with respect to the frame about a pin which is at right angles to the pivot pins of the two arms, a second member for adjusting the pivoting of the beam with respect to the frame coupled between the beam and the frame, each arm being movable between two extreme positions of pivoting with respect to the beam, which are separated by an arc of pivoting substantially greater than 90.degree., wherein when the beam is placed in the configuration of use of the stabilizing device, in a first position, said arm is folded beneath the beam, substantially parallel to said beam and, in a second position, said arm extends obliquely with respect to the beam, its sole plate being spaced apart from the beam and substantially horizontal, and when the beam is placed in the configuration of use of the stabilizing device, on the one hand, in its first position, the arm has a first of its faces, opposite the beam, disposed substantially horizontal and capable of constituting a bearing surface for the arm on the ground distinct from the sole plate of said arm, and on the other hand, the distances separating said first face, in the first position of the arm, and said sole plate, in the second position of the arm with respect to a horizontal plane are substantially equal.
