German construction company Aug. Prien is using a Sennebogen 6130 HD duty cycle crawler crane on a pontoon at a harbour in Hamburg.
The 6130 HD is working on the creation of the new Elbbrücke quarter, one part of the ongoing HafenCity Project. This involves around 3,500 sq m of the harbour basin being filled in to produce space for a subway station and building development.
This area will be enclosed and protected from the sea by a 160m-long mixed sheet pile wall, with the crane installing the king piles. Conventional ramming was not an option as an installation method, says Sennebogen, due to the vibrations produced and the sensitive caisson foundation of the nearby Elbe bridge.
