System for the storage and traction of a cable, in particular a synthetic cable fitted to an offshore crane

A system for the storage and traction of a cable,

• wherein said storage/traction system comprises a frame that carries a combination of devices cooperating with said cable:
• (i) a storage device including:
• a storage reel on which said cable is intended to be wound,
• a support, carrying said storage reel through assembly means defining an axis of rotation, and
• a motorization, adapted to rotate said storage reel about said axis of rotation,
• (ii) a traction device, adapted to exert a traction on said cable, wherein said traction device includes at least one drum associated with a motorization, and
• (iii) a winding device, interposed between said storage device and said traction device, to guide the cable during the winding/unwinding thereof with respect to said storage reel,
• wherein, between said storage reel and said support, said assembly means consist of a single slewing ring comprising two rings that are free to rotate with respect to each other:
• a fixed ring that is fastened to said support, and
• a moving ring that is both fastened to said storage reel, and, also rotated by said motorization of the storage device.
