Abstract
Improvements in folding cranes for vehicles, characterized in that the condition of folding depends on the combined relationship between the systems that make up its structure, which consist of a stable support system fixed on the platform of a vehicle, on a turning system within a horizontal plane, in a tilting system for angular retraction within a vertical plane, and in an extensible system in straight alignment, to give greater reach to the means for lifting loads inherent to the last two systems, so that the the support system consists of a base with a central through hole, with fixing means and with means for supporting the turning system, this turning system consisting of a fixed shaft and a rotating column with a gear rack and hydraulic rack arrangement, while the tilting system consists of two arms articulated to each other and actuated by hydraulic pistons, in that the first arm is articulately related to the pivoting system and the second has a fastening element for a lifting object, the extensible system consisting of a telescopic arrangement of retractable extension tubular elements within the second arm of the tilting system, driven by a hydraulic piston mounted on said second arm, and having in the second body an element for securing a load, to be used when this latter system is adopted.
