Precise lifting of heavy steel bridge components
After the start of the steel construction assembly on September 24th, 10 segments of the Grumbachtal bridge have now been assembled. The individual steel components with weights of up to 140 tons were manufactured at our headquarters in Darmstadt to the highest quality standards and delivered to St. Ingbert by heavy-duty transporters.
Massive mobile cranes with a maximum load capacity of 500 tons lifted the heavy steel bridge segments precisely onto their piers. Following the lifting assembly, the individual sections were welded together.
In the coming weeks, further parts of the steel structure (in total 4800 tons) will be delivered and installed, so that the superstructure will arrive at the second abutment before Christmas. Erection of the last two shots is scheduled for early 2021.
