ABSTRACT:
A variable-geometry stabilizing foot, in particular for earth-moving vehicles, comprising a support member (1) able to rotate about a fulcrum (3) associated with the chassis of a vehicle to be stabilized and a extendable arm (5) slidably mounted on this support member (1). A control linkage (9) is also provided, being hinged with the chassis (2) of the vehicle and with the extendable arm (5) is provided at the bottom end with a support foot (8) able to perform vertical displacements when a hydraulic jack (13) moves the support member (1) between a recovery position (15) and an operative position (16). In the recovery position (15) the stabilizing foot is thus arranged so as to be retracted and take up little space on the chassis (2) of the vehicle, while in the operative position (16), the stabilizing foot is rotated through an angle (.alpha.) towards the ground with respect to the recovery position (15). The chassis (2) of the vehicle also comprises a shaped member (14) designed to receive in abutment the support foot (8) and rotate it towards the chassis (2) when the support member (1) is brought into the recovery position (15).
