At the end of 2018, another imposing construct will be added into the list after a production time of about seven years – the Hochmoselbrücke Bridge. After completion, this bridge will be one of Germany’s largest bridges with a height of 160 meters and a length of 1.7 kilometers. It will connect both the Belgian/Dutch North Sea ports and Belgian metropolitan areas with the Rhine-Main-area. The bridge leads directly across the Mosel valley from Ürzig to Zeltlingen-Rachtig.
At the production plants in Hanover and Lauterbourg (France), the rolled steel sheets are machined for the superstructure, prefabricated and then transported to the construction site with heavy load carriers. The final assembly is performed with the help of on site SEH-developed displacement technology. The bridge superstructure consists of approx. 900 prefabricated components. With a length of 15-25 meters and a weight of 20-100 tons almost every single component is unique. During execution, production and assembly, current regulations as well as customer requirements had to be taken into consideration.
The welding equipment and burners from Kemppi have been successfully used in this project to satisfy the specific quality requirements. Kemppi’s SuperSnake sub-feeder especially facilitated operations. With this special equipment, distances of up to 25 meters could be reached with different filler wires between the MIG power sources and wire feeders. So, difficult accessibilities no longer caused problems for the expert staff. Thanks to the SuperSnake, heavy wire feeders did not have to be moved over long distances, which greatly reduced the physical load on the welders and maximized productivity.
