Abstract

An outer-boom crane includes a first boom section (1) and an outer boom (2). The outer boom is pivotable relative to the first boom section by means of a hydraulic cylinder (10) which is connected to a link system which operates between the first boom section and the outer boom and includes at least a first link (16) and a second link (17). The link system has at least four different articulations, namely a first articulation (9), a second articulation (18), a third articulation (19) and a fourth articulation (20). Further, the distance between the first and the fourth articulation (9, 20) exceeds that between the second and the fourth articulation (18, 20), the third articulation (19) connecting the second link (17) to the outer boom (2) being removed from the first articulation (9). The second link (17) can then be positioned below the first articulation or main articulation (9) when the outer boom is within its working range. Thus, the outer boom can be pivoted from a first end position by lengthening of the hydraulic cylinder (10), and be pivoted in the opposite direction by shortening of the hydraulic cylinder. In this manner, the hydraulic cylinder can operate by pushing action when the power requirement is at a maximum.
