Abstract

Improved folding boom crane, which being of which the boom joins articulately to the body or structure of the crane, making the abatement of said boom by means of a hydraulic cylinder conveniently articulated to the structure and whose shank is also joined articulately, to the boom, said cylinder being governed by an electrohydraulic power station, essentially is characterized in that the aforementioned electrohydraulic power plant incorporates a variable flow pump by means of which the speed of the movements of the boom can be regulated, within a field that extends from zero to the nominal value allowing very smooth starts and stops, as well as intermediate speeds.
