1. A crane system for a cantilever belonging to a jack-up rig, the crane system comprising:
a crane with a suspension member, the suspension member being arranged over the crane,
two skid beams attached to a lower portion of the cantilever, the two skid beams being displaceably connected to a plurality of slides arranged on the jack-up rig, so that the cantilever is movable relative to the jack-up rig via the two skid beams and the plurality of slides, wherein
the crane hangs on a first skid beam only of the two skid beams via the suspension member, such that the crane is repositionable along the first skid beam independently of the second skid beam.
