Dortmund Port
Construction on Dortmund's port which terminates the Dortmund-Ems Canal connecting Dortmund to the North Sea started in 1895. It was opened 1899 by Kaiser Wilhelm. At the beginning of the 20th century it was mainly used for the import and export ...
. The lift was the biggest and most spectacular structure on the old Dortmund-Ems-Kanal. It was inaugurated by
Kaiser Wilhelm II on 11 August 1899.
Purpose
The lift was able to accommodate the then usual Boat on the Dortmund-Ems-Kanal, 67 metres long, 8.2 metres wide, with a draft of 2 metres and lift it through a height of 14 metres to the level of the Dortmund Port.
[ It could accommodate vessels of up to 350 tonnes. A complete descent or lift cycle, including entry and exit, took about 45 minutes. The actual lowering/lifting only took two and a half minutes. This was much faster than possible using ordinary ]lock

s. This method of raising boats also conserved water at the upper elevation which relied entirely on water pumped from the lower elevation for its supply.
Technology
This technically very interesting construction managed to lift approximately 1000 tonnes of ship and water filled trough using a relatively small amount of power. The trough was supported by 5 cylindrical floats each immersed in 40 metre deep water-filled wells. The lift from the floats was the same as the load of the water filled trough therefore, only a small electric motor sufficient to overcome friction and viscous resistance was needed to set the trough in motion in either direction. Four steel worm gears, 20 metres long and 280 mm in diameter were used to direct the trough in the appropriate course.
The old lift was closed shortly after the opening of the new lift. A year later in 1963 an attempt was made to restart the old lift. It was found that the trough had tilted and that it could no longer be moved into either the fully up or fully down positions. The lift remains in this condition today and is conserved as part of a museum.
Museum
After the closure of the old lift it was decided in 1979 to develop the lift as part of the Westphalian industrial museum. The lift was restored and reconstructed without bringing it back into use. The lower dock of the old lift is used as a marina.
The old lift has an iron framework construction with five float chambers. The trough and the upper and lower control towers are accessible. In the former boiler and machine house, machines, models and pictures can be seen. In the lower dock are the former police and fireboat ''Cerberus'' of 1930 and the motorvessel ''Franz-Christian'' of 1929 with an exhibition of working life on board in the cargo hold. In the 400m long canal adjoining the upper dock there is a collection of historical ships and a loading dock along with other exhibits.
The Westphalian Industrial Museum is on the Dortmund-Ems-Kanal cycle route, the Emscher-Way.
The new boat lift
The new boat lift was opened in 1962 and has a trough length of 90 metres, a width of 12 metres, and a draft of 3 metres.[ It was capable of lifting vessels of up to 1350 tonnes. This lift utilizes the same construction principles as the old lift but using only two floats in two float chambers.
The new lift soon became too small for the navigation's requirements and a new ship lock allowing boats 190 metres long and 12 metres wide, allowing a 4-metre displaced depth was built next to the lift in 1989.
The new lift was taken out of use in December 2005 because of technical problems. The lift may not be repaired on the grounds of cost and the decreased usage of Dortmund Port. Without the lift, any problems or maintenance requirements on the modern lock would bring about the closure of Dortmund Port, as is the case in the Summer of 2021, when visitors to the site saw the lock gates dismantled and lying in the chamber for repair, causing a six week stoppage.
