Construction of a new ship lift to overcome the 36-metre altitude difference in the Oder-Havel canal.
The new ship lift at Niederfinow uses a suspended steel trough, which functions in a similar way to a lift, to enable boats to overcome the 36-metre altitude difference in the Oder-Havel canal. It is designed as a vertical lifting mechanism with a counterweight. The water-filled trough uses heavy concrete and steel weights to reach an equilibrium, with the suspension rope being diverted over 224 rollers on two hollow steel box girders.
From the west, boats travel through the upper part of the outer harbour and across the canal bridge to the trough, which is at its uppermost position. Once the western gates have been closed, the trough moves down to its bottom position. When the eastern gates are fully opened, the boat can exit the lift. When travelling from the lower to the higher water level, the process is reversed.
An umbrella joint venture was set up for the project, with an internal relationship based on separation between the consortium partners. The partners are responsible for the planning, execution and guarantee of their own services.
