The Liebenwalde lock is located at kilometer 45.30 on the Upper Havel waterway near Liebenwalde in the Oberhavel district in Brandenburg . The part of the Upper Havel waterway that branches off from the Havel-Oder waterway north to the Voss Canal at kilometer 40.50 is called the Malzer Canal , the official abbreviation of the MzK .
history
In the course of the expansion of the second Finow Canal , a first lock was built around this point in 1749. The dimensions were adapted to the coffee boats of the time and were built as a boiler lock. The resulting barrage also served to secure a sufficient flow of water for the Finow Canal. Since the lock was no longer able to cope with the shipping traffic, it was demolished in 1831 and replaced by a new building in the form of the chamber lock. The lock was completed in connection with the expansion of the Malzer Canal in 1834 and renewed in 1966, but then shut down in 1975. The gates at the head were replaced by a weir. The third lock was built in 1974/1975 and is still in operation today. It was built using steel sheet piling and has a usable length of 49.80 meters and is 10.53 meters wide.
automation
In the period from October 23, 2006 to March 30, 2007, the Liebenwalde lock was closed to all shipping traffic. During this time, the lock was modernized and the system switched to semi-automatic operation with remote monitoring from the Zehdenick monitoring center (ÜZZ). The lock process has been fully automated and remotely monitored since 2007. With the completion of the modernization and automation program, 27 of 39 locks, all 47 weirs as well as the 3 movable bridges in the portfolio of the Eberswalde Waterways and Shipping Office will be operated centrally, fully automatically or in automated self-service. Two fifty-meter-long sports boat berths and modern light signal systems were newly built in the lock area.
