Beschreibung
Zusammenfassung:	It is a rotable support (1) for inclinable masts (2) of drilling machines comprising a connecting element (C), assembled on the back side, or anyway connected with the self-propelled carriage or with the lifting mechanism of the perforating machine, on the front vertex of which a coupling element (A) fit for bearing the mast (2), rotating by two always hinged oil-dynamic pistons (P), is hinged by two hinges (C3a, C3b) with the same rotational axis and spaced one from the other in order to allow the passing between them of the elongating stem (P2).
