Embodiment Construction

[0024] Figure 1 shows a crane 10 for installation on or adjacent to a working deck of a ship, a so called anchor working crane. The crane 10 includes a base 12 and a main boom 14 driven in a conventional manner by one or more pressure cylinders 26, such as hydraulic cylinders. As mentioned above, the anchor working crane 10 according to the present invention can be installed on each side of the working deck of the ship. The crane can move along the ship on rails, for example on top of the cargo rails, and the base 12 may therefore include means to enable such movement. The crane can rotate 360 ​​degrees and thus has access to the entire working deck, behind the stern drum, outboard of the ship's side and to the winches located in front of the working deck. It should be noted that even if the expression "anchor-handling crane" is used, the crane is not limited to handling anchors only, but can also be used for other work operations on board the ship.

Abstract

The invention relates to a crane (10) for handling of chains, wires, shackles, messengers, etc., onboard a vessel, where one or more cranes (10) is arranged on or adjoining the deck of the vessel, and where each crane comprises a base part (12) with an associated main jib (14) that is arranged to be driven by a number of pressure cylinders (26). At least two rotary work jibs (16,18) arranged to be driven separately by associated pressure cylinders (28,30) are arranged to the outwardly extending end (15) of the main jib (14), and tools (34,22,24) are arranged to the outwardly extending ends (17,19) of said work jibs (16,18), for the mutual handling of said chains, wires, shackles, messengers, etc.

Description

technical field [0001] The invention relates to a crane for manipulating chains, cables, shackles, guide cables etc. on board a ship, wherein one or more cranes are arranged on or adjacent to the deck of the ship, and the cranes comprise a base, The base has an associated main arm arranged to be driven by a plurality of pressure cylinders. The invention also relates to a tool for handling chains, cables etc. on board a ship. Background technique [0002] The present invention has been developed with the aim of ensuring a safer working environment for sailors on the working deck of an anchor-working vessel. So as a result, many working methods are going to change so that the different working environments in which sailors operate become safer and easier. The trend in recent years has been to new developments placed on the bottom of the ship in addition to the anchor handling itself. Consequently, as the drilling campaign moves to deeper waters, the devices that need to be ...
