The invention relates to a system for levelling the column of an articulated basket crane, said system comprising: a hydraulic jack; support points for the jack, located on a substructure and a pedestal; and a pivot point for the pedestal, allowing the column of the crane and a turntable to be positioned at 0° in relation to the horizontal plane, thereby increasing the working range of incline, both forwards and rearwards, up to 20° in relation to the chassis of the carrying vehicle. |
