The listed Hammerbrook lock is located in the Oberhafen in Hamburg-Hammerbrook. As dam we serve the regulation of the tide of the here at this point from the Norderelbe branching lock channel. The lock chamber, whose original goals have not been preserved, is part of the city dike. The eastern extension of the structure has a centrally-mounted hinged gate with two folding rifles in the two lower corners, which were used to regulate the water level.
The lock was built from 1844 to 1847 according to plans by Johann Hermann Maack and extended in 1865/66. It was created during the development of Hammerbrook.
From 2008 to 2009, the lock was revised. The steel components were given a new corrosion protection; the elbe-sided segment gate was raised to 7.90 meters, the inland Stemmtor and the lock chamber to 7.60 meters above sea level.de.wikipedia.org/wiki/Hammerbrookschleuse
