Atlas Copco attachments help to cut back by a quarter the time scheduled for the demolition of the bridge crossing the A3


The A3 motorway passes from the Dutch/German border through the western part of the Ruhr area, the Cologne area, the Rhine-Main area and Bavaria down to the Austrian border at Stuben. It is one of the most frequented motorways in Germany. In view of the growing volume of traffic, an extension of the motorway to six lanes has become absolutely necessary. Conversion work is being carried out at a number of places located along the motorway. Near Randersacker the old bridge crossing the river Main built in 1964 was blown up and a new much wider one erected only three meters next to the old one is already in use.

After the 540 m long Main bridge was blown up, the B13 underneath the bridge was to be re-opened to traffic within merely 48 hours. This required some 1,500 cubic meters of reinforced concrete which collapsed on this particular section of the B13 to be crushed and another 800 cubic meters of a layer provided to protect the top surface of the road to be removed. Across the entire length of the former prestressed steel bridge a total of 25.000 cubic meters of reinforced concrete had to be taken care of.

Messrs. Ruppert GmbH & Co. KG Erdbau + Abbruch from Frickenhausen put their money on Atlas Copco attachments. Eight Atlas Copco medium to heavy hydraulic breakers with service weights of up to 1200-7000 kg were used for the job. Another six hydraulic pulverisers were crushing the blasted bridge fragments on the spot. „With these attachments we will be able to cope with the 25.000 cubic meters“ says Florian Ruppert, junior manager of the company. „We expect to have completed the job within four months.

On the other side of the Main a railway track intersects with the old bridge“, Ruppert continues. „This part of the bridge cannot be blown up. For this particular demolition job we have purchased the Atlas Copco CombiCutters CC 2500 U and CC 3300 U. We will attach them to Liebherr type 954 and 974 longfront excavators and demolish this bridge section from below,“ explains Ruppert. And the rubble will be a 100% recycled in their own recycling plants.
The B 13 was already cleared after only 36 hours, so that the Federal road could be opened to traffic much earlier than scheduled. „Everything went smooth.Especially the automatic lubrication system ContiLube ® II makes work easier for us“, explains Klaus Wissmann, excavator operator of Ruppert GmbH & Co. KG Erdbau + Abbruch.
