Abstract

Improvements in rotating turrets of cranes to allow greater field of action of the boom, characterized by the fact that the support of the arm or boom is substantially constituted by a piston properly governed, which, in relation to its travel, causes the positioning of the point of articulation of the aforementioned pen so that it achieves an enlarged action of the piston stroke, which in practice can reach any value.
