Lift gate
A sluice gate is called a lifting gate , which is guided on rails and lifted vertically.
Layout and function
The lifting gate of a lock consists of a flat panel that is raised above the clearance profile . It requires appropriate guidance by rails, often due to its weight also appropriate counterweights . Due to these high structures, it is now only used very rarely as the upper gate in order to avoid major changes in the landscape.
Trivia
A peculiarity of lifting gates, mostly of older design, is a long run-on of water from the gate construction and the resulting unpopularity with inland navigation and pleasure craft enthusiasts. With newer gates, for example, the water is drained to the side, this can also be seen in the video of the Minden shaft lock below.
