At each corner, connect each leg with a pin to the lower part of the gutter, and with the wheels still in contact with the rail, install the lower part of the leg so that it can be opened to both sides in the direction of rail installation. This is a shipboard gantry crane that has two cylinders for opening and closing the legs between two opposing legs.

用いた。 In FIGS. 3 to 5, pin hinges 1 are connected at both ends between the lower end of the girder 5 and the upper side of the track 8.
Legs 10 with numbers 1 and 12 were provided. A clevis-shaped cylinder 13 is installed between the legs 10 on both sides, and the action of the cylinder 13 allows both legs 10 and the track 8 to be opened on the rail 2 as shown in FIG. 4 or as shown in FIG. As shown in the figure, it was made possible to stand vertically. Further, holes 14 are provided in a part of both legs 10, and when the legs 10 are stood vertically, the holes 14, bolts, and nuts 15 can be inserted into the holes 14, as shown in FIG.
A connecting member 16 was attached between both legs 10 using a screw or the like to prevent both legs 10 from opening. Of course, if hydraulic pressure is always applied to the cylinder 13 in the state shown in FIG. 5, the connecting member 16 can be dispensed with, but that would be uneconomical and
Since it is not safe, the connecting member 16 was used in this embodiment.

If the state shown in Figure 4 or Figure 5 is to be maintained, the gantry crane 4 should be fixed to the hull 1 or the rail 2 using a known mooring device (not shown) so that it does not interfere with the ship's navigation. You can keep it off. Of course, the truck 8 is a normal wheel 9.
It rides on the rail 2 via the rail, which uses a combination of rack-shaped rails and pinion-shaped wheels.
It can also be used as an aid to the mooring device.

ーン４は船体１又はレール２に固定させておく。 During voyage, after the connecting member 16 is removed, the cylinder 13 is used to open the legs 10 to shift to the state shown in FIG. 4, lowering the center of gravity of the gantry crane 4. Of course, the gantry crane 4 is fixed to the hull 1 or the rail 2 so that it does not move due to the rocking of the ship.
［発明の効果］
以上のように、本発明においては、航海時に脚
