Abstract

Mixed crane applicable on truck, perfected, characterized in that it is constituted by an elongated base that has a rocker with three points of support with which it makes effective its coupling to the chassis of the truck in transverse direction, and that is constituted at the same time in deposit of the fluid.: hydraulic drive, holding up a: column.what is mounted rotatably at a point laterally displaced from the base and is coupled to its cusp or inclined head of forked constitution, a determining arm of a tubular piece that at its coupling end it generates a pair of lugs, obliquely projecting, constituting a broad elbow that embraces the head of the column, being connected to it by means of an articulation pin and by means of a hydraulic cylinder that is stretched on the one hand between the branches of the head and another between two lugs protruding from the lower edge of the arm, to be in an oblique position arm when it is folded down obliquely to the other side of the base; said arm has several extension bodies assembled in telescopic organization together with internal hydraulic cylinders, although the last of these bodies is of manual extension and ends in a fixed pulley; this arm also has at its coupling end an upper wing that arises from the apex in opposition to the elbow, laterally carrying a hydraulic winch, whose cable extends until passing through the pulley, ending in a hook or in a mobile pulley, but passing over the arm resting on a sheave incorporated between two lugs protruding from the upper side thereof.
