Container ship skr an

The invention relates to a ship crane which is used for loading and | Unloading containers onto and from a ship is used. It is particularly useful to have a relatively inexpensive and compact loading and unloading facility of containers in and out of a ship on one or both sides of the same.

Container ship cranes are known and already in various Forms available. One form consists of a gantry crane with rotating arms that can be swiveled, so that they cover the deck of the ship or the dock. However, the manufacture and operation of such cranes is expensive. In addition, they are bulky and in theirs Movement too restricted to work in certain dock areas and load certain ships or parts of them or to discharge.

The American patent 3 1) 0 840 shows a different one Form consisting of a lever trolley and a driven trolley forming a counterweight, which is supported by an extendable Carriers on rails across the ship deck and each Side of the ship can be guided, with the from ζ ie Daren carriers in turn above the Schiffsdeoks of C-shaped Supports are carried on spaced parallel roadways running along the slope adjacent to each side the same are arranged. Such a crane device is 1st

relatively compact and can be used over almost any cargo area, and deck area can be operated. However, their use is limited from an economic point of view because their manufacture

maintenance are costly. ., -,

The present invention overcomes these difficulties and disadvantages and provides a compact container ship crane, which is relatively cheap to manufacture and maintain.

A container ship crane operating on spaced-apart lanes movable, which adjoin each side of a ship's deck and are essentially parallel to the center line of the ship, is characterized according to the invention by a single main beam, which extends transversely to the ship's deck, through legs, which are movably arranged on the lanes of the ship's deck, to support the main beam in the vertical direction above the ship deck, by a drive device which the Propels legs along the carriageway, through a single retractable beam that is movably mounted on the main beam is for the purpose of movement transversely to the center line of the ship from a limit position in which the retractable beam extends over a Side of the ship extends into an opposite limit position, in which the extensible beam extends over the opposite side of the ship, by a lifting device, which is movably arranged on the extendable beam for movement transversely to the center line of the ship from an end part of the extendable beam to an opposite end portion of the extendable Carrier, as well as by a power source, which is the extendable Beams moved along the main beam and the lifting device moved along the extendable beam.

The power source is preferably located substantially in the center of the extendable beam so that it is the main support for the pull-out carrier. Only a single source of power is provided to move the extendable beam along the main beam and to move the lifting device synchronously along the telescopic beam. In addition, are preferably on each end portion the retractable support guides attached to the retractable to lead ren girder along the main girder and also around the ab-
