Neues Schiffshebewerk in Niederfinow - Überblick und technische Aspekte
|Published in:||Stahlbau, July 2015, n. 7, v. 84|
New ship lift at Niederfinow, Germany.
A second ship lift is to be constructed in Niederfinow adjacent to the existing lift. After extensive preliminary studies, the Federal Waterways Administration decided on a vertical lift with balancing counterweights. A load-bearing structure consisting of reinforced concrete towers, columns and cable pulley girders, all with foundations in a common trough well, transfers the loads from the water-filled trough (9 000 t) into the bedrock via cable pulley girders. The trough, which is suspended on cables and balanced with counterweights, has a usable length of 115 m, a usable width of 12.5 m and allows a water depth of 4.0 m. Vertical movements of the trough take place by means of rack and pinion drives. A safety system consisting of internally threaded columns and rotary locking bars ensures that the trough stops safely in an emergency.
