Thannhauser + Ulbricht Straßen- und Tiefbau of Fremdingen in Southern Germany, is currently upgrading the country's B 2 federal highway near the town of Roth and employing four new 695 Doosan DA30 articulated dump trucks (ADTs) and a new Doosan DX490LC-3 crawler excavator for the earthmoving work. The machines belong to the rental fleet of Rühle Maschinenpark, based in Untermünkheim-Haagen, South West Germany.

The B 2 is one of Germany's oldest highways and runs the entire length of the country for a distance of 845km from north to south.  South of Nuremberg, it forms one of the most important connections between the city of Nuremberg and Augsburg.  Due to high traffic volume, a stretch of 3.6km is now being widened from two to four lanes near the town of Roth.  

Part of the road being doubled in size requires not only the construction of an extra carriageway and new bridge, but also some 275,000m³ of excavated earth to be moved. The quality of some of the excavated earth will be improved, before it is put back in place, while the rest will have to be taken away from the site.  

Since the start of construction work in April 2013, ten hectares of forest land has been cleared and 61,000m³ of surface soil removed, with the project planned for completion in 2014. Shortly after the project began, it became evident that due to the high proportion of sand in the ground, coupled with heavy rainfall saturating and softening the earth, the composition of the excavated soil made it unsuitable for hauling away with conventional construction site trucks. This led to Tannhauser + Ulbricht seeking a company that could provide them at short notice with four ADTs and a 50tonne excavator on a long-term lease basis.

Rühle Maschinenpark was able to meet this requirement, supplying the five heavy-duty machines within ten days.  The firm's director, Achim Rühle, said, "Though we didn't have four dump trucks ready in the yard, through our position as a Doosan dealership, we were able to obtain the machines from the Doosan fleet holding to meet our client's needs."
