Abstract

Improvements in mobile rotating cranes, characterized by a rotating arm capable of executing a rotation of 360º, comprising the mentioned arrow of at least three elements, two of which are capable of being closed like a book, while one of them is retractable, with with respect to the third, like a telescope with long view to obtain the minimum dimensions of the arm when the crane is in rest position, as well as a perfect regulation of its length during operation; the crane is further characterized by the fact that the vertical movement of the mentioned arm is regulated by a hydraulic apparatus represented, by a fixed cylinder, in which and with respect to which there is a rotating, concentric collar of the piston which causes the lifting; as said collar is integral with a pair of uprights and with tie rods, on one side on said uprights, and on the other hand its opposite end, on the rear end projecting from the arm of the crane, the realization of a lever of the third will be obtained grade.
