Abstract

Crane on truck, perfected, characterized in that it comprises a base-bridge installable in transverse direction that holds up a point laterally displaced to a column of forked constitution that ends in a head finished in point, carrying coupled an arm. Constituted by a piece of profiling "U" whose lateral branches determine a lower side or edge of double slope giving; origin to an expanded central zone; this arm embraces with its end the cusp of the head of the column relating to direct articulation between its branches and the cuspid and with a hydraulic cylinder that extends tied on one side between the branches of the head and on the other between the branches of the arm in a point of the central zone located at half height, said arm being folded down obliquely towards the other side of the base with the cylinder in an oblique direction; the other end of the arm is constituted broken in elbow with a second arm attached to it, which is provided with a telescopic organization of extension bodies and has its elbow coupling end similar to that of the first arm, connected to it by direct articulation. At a point displaced downwards from the lower edges of both arms, and by means of a hydraulic cylinder that extends moored to the same point of the first arm as the other cylinder, being connected on the other side to two tie-rods connecting respectively with the first and second arm in the upper vertices of their elbows, being slightly longer the link attached to the second arm in the same upper edge of this, to be the second arm folded under the first with, its lower longitudinal edge tucked in he.
