Henrichenburg boat lift
The old ship Henrichenburg of 1899 and the new 1962 are only a few hundred meters from each other and belong to the channel level Henrichenburg the federal waterway Dortmund -Ems Canal in Waltrop upper meadow. They are named after the former municipality Henrichenburg, today the northernmost district of Castrop- Rauxel, which extends to the terrain of the south to close. Responsible is the Waterways and Shipping Office Meiderich.
The old lift was in 1914 supplemented by a shaft lock with two five- saving basins. In 1958 to 1962, built the new float - lift, so that 1969 was followed by the closure of the old elevator. The old shaft lock was replaced in 1989 by a sluice with two saving basins. By the year 2005, the operation of the new elevator and the new lock ran parallel. Since then, the ship traffic flows only through the lock. All four buildings are part of the sluice parks Waltrop.
The old boat lift
The old boat lift was built by the company Haniel & Lueg according to the plans of the Szczecin ship civil engineer Rudolph Haack. It was a key building in the Dortmund- Ems Canal, because only with its completion of the canal could be traveled to the Port of Dortmund. This lift is the largest and most spectacular structure of the first construction period of the Dortmund- Ems Canal. It was taken on August 11, 1899 in the presence of Emperor Wilhelm II, together with the Dortmund -Ems Canal in operation.

Technology
The elevator was to lift able then usual Dortmund- Ems canal barge normal of 67 meters in length, 8.2 meters wide and 2 meters draft to 14 meters on the water retention of the Dortmund harbor. In the late 1950s the underwater was raised by 50 cm, thus the drop height was reduced to 13.50 meters. A complete lowering or lifting operation, including entry and exit, only took about 45 minutes. The actual lowering or lifting process took about 12.5 minutes. This went much faster than with the conventional locks at the same time. Moreover, hardly lifting the water consumed from the Dortmund attitude whose entire water had to be provided from the lower posture by pumping.
The technically very interesting design came at a relatively low drive power from the lifting of the 3100 -ton water-filled trough. The solution lay in the buoyancy of the five float ( air-filled hollow cylinder), in 33 meters deep immersed separately, water-filled well shafts. Your lift was as large as the weight of the trough, which is always the same regardless of the size of the ship, because the ship displaces when entering the trough as much water as it weighs. Thus, a relatively small electric motor sufficient, with about 110 kW, to overcome the frictional resistance in order to set the tray up or down in movement. To motion controlled four 20 -meter-long threaded spindles made of steel with an outside diameter of 280 mm. The spindles were given a longitudinal bore of 110 mm inner diameter to detect any errors in the material and to protect them in freezing temperatures with exhaust steam from freezing.
Museum
After the commissioning of the new lift at the old lift was finally shut down in 1969. Then it fell into disrepair. A demolition was initially considered. The Regional Association of Westphalia -Lippe ( LWL), however, decided in 1979 to take advantage of the technical monument as the site of the Westphalian Industrial Museum, today LWL Industrial Museum. After restoration and reconstruction of the old boat lift without restoring the original function together with its lower outer harbor (underwater ), the upper outer harbor and a piece of duct ( headwater ) is opened as a museum. The lower outer harbor is used as a marina.
The old boat lift is an iron truss structure with five float shafts. The trough and the stone head and lower main towers are accessible. In the former boiler and engine house machines, models and pictures can be seen. In the upper outer harbor, the police and fire-fighting boat Cerberus of 1930 and in the lower outer harbor the motor cargo vessel Franz- Christian from 1929 are with the exhibition A working life on board in the hold. On a 400 m long channel section following the upper outer harbor, the museum displays a unique collection of historic ships, including the steam tug Fortuna and the only one in Europe still existing steam tanker phenol. These are here floating tools, a landing and loading dock for cargo vessels, a Hellinga able to ship repair with historic crane from 1906 and the channel passage with old Klapptor of 1914 and a historic lift bridge by 1897. The reconstructed port building temporary exhibitions can be seen.
The boat lift is due to the bike paths Dortmund -Ems canal route, Emscher- way and on the route of the industrial culture by bike The Old Ship Henrichenburg is today central anchor point of the Route of Industrial Heritage.

The new lift
The new lift was opened in 1962 and has a trough length of 90 meters and a width of 12 meters and 3 meters of water depth. The useful quantity is 85 m × 11.40 m × 2.50 m ( effective length effective width × depth × ). These dimensions allow the then emerging Europe ship the passage.
Technically, the new lift has the same design principle as the old, but the design was simplified. The number of swimmers in 52.5 m deep shafts was reduced for the balance of the trough weight of 5000 tonnes to two and a sub-main is not necessary as trough and Haltungstor are designed as rotating segment gates ( they turn down away). The spindles are located in four separate towers standing on a connecting lift scaffolding was omitted.
The new lift was soon too small for the requirements of the shipping channel. So next door today's economic sluice with a length of 190 meters, 12 meters wide and a threshold depth of four meters in 1989 immediately established.
The new lift was used until December 2005, then taken out of service due to technical problems. A new start-up is questionable for reasons of cost, especially since the Dortmund Port is no longer the freight volume has earlier days today. If, however - as in the spring of 2006 - to problems or maintenance work on the modern lock, the Port of Dortmund can not be started.
In order to fight for the preservation of the elevator, a development association has since founded. He wants to get the elevator not only as a building, but also in good working condition.
Since 5 December 2005, the new lift is registered as a historic landmark in Part A of the monument list the city Waltrop.
