Improved articulated hydraulic crane, characterized in that it is integrated by a frame from which emerges a column capable of turning on a vertical axis, a forearm joined at its end to the column and capable of folding in a vertical plane and an extension arm attached to the forearm at its end and susceptible to refolding in a vertical plane; having the column and forearm in the vicinity of its articulation, bracketing configuration so that a hydraulic cylinder anchored to both determines in its extension the unfolding between both elements while in its contraction, when lodging between the two plates in fork allows a total dejection of the two elements until they are folded back against each other.
