Fehmarn Sound Bridge
Project description
As a dual purpose bridge for road traffic and railway, the Fehmarn Sound Bridge connects the island of Fehmarn in the Baltic Sea with the mainland near Grossenbrode.
It was built in 1963, simultanously with the Puttgarden ferry port on Fehmarn. Thanks to the crossing, the average travel time between Hamburg and Copenhagen had been significantly reduced.
The total length of the bridge is 963 meters with 337 meter-long ramps, which carries traffic over the 1,300 meter-wide Fehmarn Sound. The main span of the structure stretches 23 meters above the sea level and provides a 240 meter-wide cleareance for ships.
The bridge has a steel superstructure consisting of three smaller substructures.The test report on the main bridge found that the existing bearings (pot bearings) are in poor condition, thus had to be replaced with new ones.
mageba scope
For this structure mageba produced two RESTON-SPHERICAL bearings.
The maximum displacement of the bearings is 500 mm, with a load capacity of 2,500 tons. Each bearing weighs approximately 2 tons.
During the design stage of the products, the fact, that road vehicles and trains run parallel on the bridge, had also be taken into account.
Since the client requested the replacement to be implemented without traffic restrictions on the bridge, mageba developed a concept using a pontoon and a telescopic forklift. A 30 x 20 meter pontoon was “floated” to the installation site, carrying a large telescopic forklift with the capacity to lift the bearings 25 meters high.
