Huge Floating Crane Lifts Bridges and Submarines

Like some Godzilla monster, the giant crane looms over the city

Early in the morning it arrives at the city dock to begin the bridge construction for the man-made island in Kagoshima bay. Boom length: 132m. Lifting capacity: 3700 tons!
It's "Yoshida" - Japanese biggest floating crane, built by Mitsubishi heavy Industries Division.

Each hook is 10 meters tall. The workers around it look as small as ants.
Some 800 steps lead to the tip of the boom, to the small cabin on the top.

Another day's job -
transporting a submarine


The Japanese submarine SS-600 Mochishio is lifted at the Kobe Kawasaki yard. The Mochishio is the last of the Oyashio-class and is approximately 84m in length. (thanks JB for info)
