Automobile tower crane characterized in that in the superstructure, rotating on the translational chassis, a tower frame is constituted by a vertical support articulated on the lower front edge of the superstructure, two bracings articulated to a trestle attached to said superstructure. Upper zone and another support which is articulated at one end to the corresponding one of the posterior greater bracing and by the opposite one to a plate to which the vertical support and the minor bracing are also articulated; said minor bracing acts as a diagonal in the quadrilateral formed by the two supports, the greater bracing and the superstructure itself, thus ensuring the non-deformability of said polygon.
