Abstract

A crane has a post (1) and a jib (2) which can be pivoted by means of a hydraulic cylinder (3) and which is connected to the post by means of at least two links (16, 17) of different length. The links are connected to the post and the jib by means of four articulations, namely a first articulation (18), a second articulation (19), a third articulation (20) and a fourth articulation (21). The long link (17) guides the articulation connecting the hydraulic cylinder (3) to the jib in a first path of movement about the third articulation (20) when the hydraulic cylinder is lengthened and shortened, respectively, at the same time as the short link (16) mechanically guides the second articulation (19) connected to the jib in a second path within the first path, while raising and lowering, respectively, the jib in its entirety.
