The main pumping station "Unteres Rheinufer" in Ludwigshafen has been in operation since the end of the 1970s.
In connection with the overall refurbishment of the pumping station, the bar screen system was also to be mechanically refurbished or replaced. As the operation with the old screens with screenings discharge in the basement was uncomfortable and no longer up to date, these were to be replaced by Multi Rake Bar Screens with screenings discharge on the ground floor.
After filling the screenings container, it had to be lifted to the ground floor with a portal crane and transported outside to the container storage area. There the containers could only be moved on roller bars arrangedlengthwise and crosswise.
