YOSHIDA-GO No. 60, Most Powerful Full Revolving Crane Vessel in Japan
YOSHIDA-GO No.60, the 1,700 tons Lifting Full-Revolving Multipurpose Working Vessel was built it's hull at Oppama Shipyard, Sumitomo Heavy Industries, Ltd. and towed to their Niihama Works in order to be equipped with the gigantic crane. Then, she was completed and delivered to Yoshida-Gumi Co., Ltd. in March 1996. YOSHIDA-GO No. 60 is the most powerful full-revolving crane vessel in Japan and expected to be active in the ocean civil engineering field in the next century.
Hull
1. The spuds and the thruster make it more efficient in mooring works.
2. The large sized hull makes it possible to enhance the efficiency in the operation even under the rough sea conditions.
Crane Works
1. The full-revolving type makes it possible to do crane works even the broadside.
2. Dismantlement of the A-frame of the crane makes it possible to pass through under the existing bridges (over 25m height).
3. Installation of the flying jib makes it possible to extend the slewing radius to 100m.
4. The auxiliary crane is useful to do crane works safely and rapidly.
Piling Works
1. The full-revolving type makes it possible to do piling works even the broadside.
2. The telescopic catch-fork makes it easy in slant piling.
Max. gradient of pile : ±27°
3. The extended and shortened leader makes it easy in controlling the height of the leader top and under water piling works.
4. The auxiliary crane makes it possible to hang piles safely and rapidly.
