The Alsleben lock , locally and colloquially sometimes also called the Mukrena lock , is a lock on the Saale federal waterway . The Alsleben lock system is located in the state of Saxony-Anhalt in the Salzlandkreis in the Mukrena district of the town of Könnern , immediately east of the city center of Alsleben near Saale - km 50.32. It was opened to traffic on December 18, 1939. The Magdeburg Waterways and Shipping Office is responsible for operation and maintenance . Since July 1, 2010, the lock has been remote-controlled via the Bernburg Revierzentrale and is therefore no longer manned. Registration for the smuggling takes place by phone.
history
The use of the Saale for goods or passenger transport has been documented since 981. It is reported in chronicles of the Saale shipping that the water of the Saale river was dammed as early as the second half of the 14th century . The accumulated amount of water was used to operate mills and rafts. On October 21, 1530, Emperor Karl V granted the archbishopric of Magdeburg the privilege of free navigation on the Saale and permission to expand the river. The first wooden locks were used by the boatmen to handle freight traffic. Prince Wolfgang von Anhalt , regent of Bernburg, signed a contract in 1559 at the urging of Archbishop Sigismund to expand and secure shipping on the Saale. Not until almost 100 years later, from 1790 onwards, shipping on the Saale was further expanded. The Elector of Saxony, Friedrich August III. ordered the upper hall and the Unstrut to be made navigable. As part of the Elbe / Saale waterway expansion, the total length was shortened by straightening in the years 1933 to 1942 from 427 kilometers to around 413 kilometers. From km 124.16 near Bad Dürrenberg to km 0.00 confluence with the Elbe (at km 290.78) the Saale is a federal waterway.
In Alsleben there were already locks in the Saale. (Quote) In the city, near the Mühlen Thore, there is the zum Ritter Guthe or Fürstl. Amte Alsleben-owned mill with 6 grinding courses, in addition to an oil cutting and walck mill, and on the dam, but beyond the Saalstrohm to Amte Beesen, the Pregel-Mühle belonging to Amte Beesen, where the lock is itself, through which the ships pass that formerly 1581 in September von Holz, and after the Schiffahrtth on the Saale had been rebuilt at the end of the Seculi, it was rebuilt from Quatersteinen (end of quote). Another lock is mentioned before 1698. and was suitable for the passage of barges with hall dimensions .
description
The current Alsleben lock is a tow lock. The laterally offset lock gates are typical of this type of lock. The entrance width of the upper and lower head, ie the gate width, is 12 meters. They widen towards the middle and the usable width is then 20 meters. As a result, several barges of a tugboat can lie next to each other in the lock and can be locked together. The usable length of the lock chambers is around 100 meters. The lock walls are made of concrete and are vertical. The lock heads are also designed as heavy-weight concrete walls. Both lock gates were built as lifting gates . The lift gates have no openings for filling the lock. The lock chamber is emptied and filled by lifting the gates. Part of the lock system is a bridge north over the lower head of the lock. A municipal road leads over the lock canal and is the only access route to the lock island.
