Abstract (en)
[origin: EP0469182A2] A device for the lifting, lowering and the water carriage of very heavy loads in the range of between about 6000 and 10000 tonnes, in particular in bridge construction over open stretches of water, is described. Provided as an alternative is an intermittently working device with a lifting mechanism, consisting of at least one portal arranged on barges set apart by the width of the very heavy load, at least one intermittently vertically adjustable supporting member per portal, and a supporting framework which in turn has barges, variable in their depth of immersion by flooding or pumping out water ballast, and is provided with supporting towers consisting of separable segments. In the other alternative, a continuously working and thereby quicker lifting mechanism of identical construction in principle is provided, the supporting members of which are, however, also vertically adjustable under load.
