ALPINE and Grund-, Pfahl-, und Sonderbau implements two measurements. Additionally, the flood control dam is reinforced which separates the Danube channel from the inner harbour. A gigantic harbour gate is being installed at the harbour entrance. Like a sliding gate it can be closed in case of a flood.
The harbour gate has enormous dimensions. It is 30 metres long, 13.5 metres high, weighs (without mounting parts) about 203 tons and is made of pure steel. It is 2 metres wide to be able to resist the pressure from a flood.
VAM GmbH & Co KG Anlagentechnik und Montagen manufactured the harbour gate. The gate is composed of four individual parts with weights of 52.7 – 40.4 – 40.1 and 70.4 tons. After manufacturing in the factory in Wels they were treated with corrosion protection at the company Bauschutz Linz.
Then they were transported to the Viennese harbour by heavy-goods trucks. This is were they are currently stored.
The gate parts will be lifted in place from December 14 – 21, 2009.
The Viennese harbour is the largest Austrian trimodal logistics centre and features simultaneous connections to ship, train and truck routes. About 12 m tons of goods and about 1.700 ships are handled annually.
