<p>The crane comprises a mast (6), foldable or telescopic, at the top of which there is articulated in a centred position about a pivot (23) a foldable jib (10), consisting of two or more elements (11, 12) articulated to one another. This crane also comprises a motorised unfolding/folding device, the mast (6) and the jib (10) defining a median vertical plane (P) in the deployed working position. According to the invention, the articulation pivot (23) of the jib (10) at the top of the mast (6) is inclined at an angle (A) in relation to a direction (60) perpendicular to the plane (P). The articulation pivots (37) between the jib base (11) and the following jib element (12), and if the case arises between the successive jib elements, are inclined by an angle (B) in relation to a direction (61) perpendicular to the plane (P). Thus, in the folded transport position of the crane, the jib element(s) (12) other than the jib base (11) are postioned laterally in relation to the mast (6) which leads to optimum space requirement. <IMAGE></p> |
