Abstract
Transported hydraulic crane, which is essentially characterized because it is constituted from a rigid cellular structure that completely covers the one designed to be placed on a heavy truck, chassis of the carrier truck, being mounted in the upper central part of said structure a seat for a bearing of large diameter while on the sides of the structure there are pairs of transverse housings for telescopic beams that extremely incorporate vertical support jacks, driven, like the extendable beams, by hydraulic cylinders of double effect, having been planned to place on the large diameter bearing a rotating structure in a horizontal plane, to which a telescopic arm of several sections is articulated, the arm being operated in a vertical plane by means of two double-acting hydraulic cylinders, while the telescopic sections are extensible through a hydraulic cylinder aulico of double effect, being independent the accionamiento of any of the hydraulic cylinders of the crane with regard to the rest of them and also independent of the movement of rotation of the rotating structure, whose change of position, within a horizontal plane, is carried out through of a reducer whose vertical force axis has a pinion that permanently meshes with the internal toothed periphery of the large diameter bearing that supports the assembly.
