"Yoshida" - Japanese biggest floating crane

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.

The task is to lift the whole bridge sections, each weighing approx. 3500 tonnes:

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