Launching of Oder Spree canal bridge, Germany
ALE has completed the launching of the Oder Spree canal bridge, weighing 600t and measuring 74m in length, in Brieskow Finkenhead, Germany.
The bridge was built 30m behind the first abutment and the bridge was driven over the first stationary skidding plates, which were installed on the abutment, using 14 axle lines and 18 axle lines of SPMT.
With 14 axle lines of SPMT remaining under the end girder of the bridge during the launching, the bridge was pulled forward over the stationary skidding system by means of two strand jacks.
The bridge was then skidded 24m and a LR1600 crane was used to support a part of the bridge weight. The maximum lifting weight in the crane gradually reached up to 300t (half of the bridge).
Once the bridge was moved over into its final position the weight was transferred onto two climbing jacks on each side (4 x 500t) and the stationary skidding systems were removed.
After the removal of the skidding system, the bridge was jacked-down 2m onto supports.
