A hydraulic crane comprising: - a hydraulic cylinder (10) for pivoting an outer boom (8) in relation to an inner boom (6); and - a link system comprising a first pair of link elements (13a, 14a) and a second pair of link elements arranged in parallel with each other on opposite sides of said booms at the joint (9) between them, wherein said hydraulic cylinder at its outer end is articulately connected to the first pair of link elements. The first and second pairs of link elements are connected to each other by a cross bar element (15), wherein the link elements are configured to mechanically guide the cross bar element in an arcuate path about said joint so as to make it assume a position below the joint when the crane is in a working position and a position above the joint when the crane is in a Z-shaped parking position.
