ABSTRACT:
The rotatable support for inclinable masts of drilling machines includes a connecting element connected to the lifting mechanism of a drilling machine, and including two essentially parallel planar elements having an essentially triangular or trapezoidal shape, on the vertex of which a coupling element configured for bearing the mast is connected. The coupling element is rotated by two pistons, and is coupled to the connecting element by two hinges having a common rotational axis and spaced one from the other, in order to allow the passage of the piston rods between the hinges.
