ABSTRACT:
A support head for television or motion-picture cameras able to allow horizontal and azimuthal panning shots, is made up of balancing member and device of control and adjustment of both horizontal and azimuthal movements. The device for the control and adjustment of azimuthal and horizontal movements includes a braking element and a braked element, assembled on the same axis and each made up of a series of facing annular surfaces. The annular surfaces of the braking system engage in the spaces between adjacent facing surfaces of the braking element. A high viscosity fluid is arranged between the facing surfaces of the braking and braked elements. The device for actuating the braking element for adjustment of azimuthal movement is made up of a screw control arranged inside the support head, rotating inside a hollow shaft element slidable in a longitudinal direction and having slot ports on its outer surface.
