Embodiment Construction

[0045] figure 1 An offshore crane 1 (also referred to as "crane 1") shown generally in , is suitable for offshore applications.

[0046] Such a crane 1 is advantageously designed to be mounted on a vessel (not shown - also called "offshore vessel") for offshore applications. The crane 1 is thus suitable to be brought on board an "offshore" vessel.

[0047] The term "vessel" includes, for example, vessels, in particular marine vessels, in particular ships, floating cranes, offshore barges and other offshore platforms.

[0048] Thus, the crane 1 is used for, but not limited to, installation or dismantling of transport infrastructure, on-board maintenance or operation.

[0049] Crane 1 consists of three main elements:

[0050] - the supporting structure 2, which constitutes the interface of the crane 1 with the vessel,

[0051] - a boom 3 carried by the supporting structure 2, and

[0052] - storage / drawing system 4 for manipulating cables C intended to suspend / receive a loa...

Abstract

Disclosed is a system for the storage and traction of a cable, in particular a synthetic cable fitted to an offshore crane. The storage / traction system (4) includes a frame(5) that carries in particular a storage device(6) including a support (62)carrying a storage reel (61) through an assembly (63)defining an axis(61') of rotation. Between the storage reel(61) and the support(62), the assembly (63)includes a single slewing ring (63) including two rings that are free to rotate with respect to each other: a fixed ring(631) that is fastened to the support(62); and a moving ring (632)that is, on the one hand, fastened to the storage reel (61)and, on the other hand, rotated by a motorization(65).

Description

technical field [0001] The invention relates to the technical field of offshore cranes. The invention relates more particularly to a system for storing and pulling cables, in particular synthetic cables mounted on offshore cranes. Background technique [0002] In the offshore sector, the ships used are usually equipped with at least one crane. Certain cranes include, for example, knuckle boom cranes. [0003] Cranes may be used for, but not limited to, installation or dismantling of transport infrastructure, on-board maintenance or operation. [0004] In order to perform these operations, these cranes are usually provided with systems for storing and pulling cables intended to be attached to the load to be moved. [0005] This storage / drawing system comprises for this purpose a frame carrying a combination of equipment cooperating with said cables: [0006] (i) storage devices, including: [0007] - a storage reel for winding said cable, [0008] - a support carrying s...
