After the ship stored in the container is sailed to a dumping position in the ocean, the hatch cover is removed and the crane main body 5 is driven to bring it above a predetermined container 3. Next, extend the piston rod of the first cylinder 22,
The rotation frame 20 in the state shown in the imaginary line in FIG. 7 is rotated in the direction of arrow H to bring it into the state shown in the solid line in FIG. Next, the piston rod of the second cylinder 26 is extended, and the piston rod of the second cylinder 26 is extended.
The pin 25 is connected to the bracket 23 of the upper lid 3B as shown by the solid line in the figure. Next, after releasing the fixation of the upper lid 3B, the piston rod of the second cylinder 26 is retracted and the upper lid 3B is lifted as shown by the imaginary line in FIG. Next, move the crane main body 5 to above the adjacent container 3, then extend the piston rod of the second cylinder 26 and open the upper lid 3B to the adjacent container 3.
, and pull out the pin 25. Next, the crane body 5 is moved and brought above the original container 3. Next, the winch 46 is operated to rewind the wire rope 47, and the shooter 16 is rotated in the direction of arrow F, bringing the tip of the shooter 16 close to the sea surface.
Next, the traversing carts 9 and 10 are moved to bring the lifting rod 13 directly below a predetermined drum can 4. Next, the fifth cylinder 44 is operated to rotate the gripping arm 43 in the direction of arrow M. Next, the pinion 32 is rotated in one direction by a drive device (not shown), and the rack 31 is rotated in one direction.
The lifting rod 13 is lowered via the. As a result, when the gripping pawl 45 is inserted into the gap between the drums 4 and reaches a position facing the outer peripheral surface of a predetermined drum 4, the rotation of the pinion 32 is stopped. At this time, the lifting rod 13 is
When the gripping device 14 is misaligned, the third and fourth cylinders 39 and 40 are operated as appropriate to remove the gripping device 14.
The gripping claw 45 may be inserted into the gap between the drums 4 by swinging the drum. Next, the grip arm 43 is rotated in the direction of arrow N by the fifth cylinder 44, and the drum 4 is gripped by the grip claw 45. Next, the pinion 32 is rotated in the other direction, and the drum can 4
is suspended and brought above the shooter 16.

適である。Effects of the invention As described above, according to the invention, the lifting rod is raised and lowered to lift and lower the drums, so even in severe ocean conditions, the drums can collide with the ship's hull like a conventional crane. The chute can be carried out reliably and safely without any problems, and by activating the oscillation mechanism to lay the drum on the chute in the longitudinal direction and releasing the gripping device, the chute can be slid down to the sea surface in an extremely stable position. This reduces the impact when the drum enters the sea, prevents damage to the drum and spills of contents, and allows safe dumping on the sea surface.
Therefore, it is ideal for dumping low radioactive waste into the ocean.
