A stabilization apparatus for lifts, handlers and air platforms, comprising: at least one main body, adapted to be assembled onto a vehicle, equipped with at least two lateral branches, at which respective first arms are rotoidally coupled; second arms, each rotoidally coupled to a respective first arm, defining, together with said branches, relative articulated stabilizers, wherein said stabilizers are movable between a retracted position in which they are folded onto themselves, and an extended position wherein they are unfolded, thus defining a stabilization position; characterized in that: the second arm of each stabilizer has a length less than that of the first arm; in the retracted position of each stabilizer, the first arm is arranged substantially vertical, whilst the second arm is positioned at least partly overlapped to the first arm; in the retracted position of each stabilizer, the first and second arms (11, 12) are arranged above the relative branch of the main body and adjacent one to another, thereby defining together a vertical encumbrance which is substantially determined by the length of the first arm; and the main body and the first and second arms (11, 12) are sized such that the vertical encumbrance of the apparatus in its entirety is equal to that of the folded stabilizers in the retracted configuration thereof, whereas the side encumbrance of the apparatus is substantially equal to that of the main body. at least one main body, adapted to be assembled onto a vehicle, equipped with at least two lateral branches, at which respective first arms are rotoidally coupled; second arms, each rotoidally coupled to a respective first arm, defining, together with said branches, relative articulated stabilizers, wherein said stabilizers are movable between a retracted position in which they are folded onto themselves, and an extended position wherein they are unfolded, thus defining a stabilization position; characterized in that: the second arm of each stabilizer has a length less than that of the first arm; in the retracted position of each stabilizer, the first arm is arranged substantially vertical, whilst the second arm is positioned at least partly overlapped to the first arm; in the retracted position of each stabilizer, the first and second arms (11, 12) are arranged above the relative branch of the main body and adjacent one to another, thereby defining together a vertical encumbrance which is substantially determined by the length of the first arm; and the main body and the first and second arms (11, 12) are sized such that the vertical encumbrance of the apparatus in its entirety is equal to that of the folded stabilizers in the retracted configuration thereof, whereas the side encumbrance of the apparatus is substantially equal to that of the main body. the second arm of each stabilizer has a length less than that of the first arm; in the retracted position of each stabilizer, the first arm is arranged substantially vertical, whilst the second arm is positioned at least partly overlapped to the first arm; in the retracted position of each stabilizer, the first and second arms (11, 12) are arranged above the relative branch of the main body and adjacent one to another, thereby defining together a vertical encumbrance which is substantially determined by the length of the first arm; and the main body and the first and second arms (11, 12) are sized such that the vertical encumbrance of the apparatus in its entirety is equal to that of the folded stabilizers in the retracted configuration thereof, whereas the side encumbrance of the apparatus is substantially equal to that of the main body.
