After over three years of construction, the new Aurach Bridge near the Regau junction opened to traffic in early September. Three WOLFF 7534.16 Clear cranes were deployed on behalf of the Habau/Porr joint venture to support the demolition and reconstruction of the A1 West Motorway bridge. Long-standing Wolffkran customer Habau supplied the flat-top cranes, each with a maximum load capacity of 16.5 tons. The cranes, installed in 2022, were mounted on two 77.6-meter towers and one 64.1-meter tower.

The cranes handled demolition of the old bridge and the transport of reinforcing steel, formwork elements, precast concrete components, construction vehicles, and concrete for the new superstructures and piers. Freestanding loads of up to 13 tons were lifted safely. After approximately three years on site, the cranes were dismantled in March 2025.

Precise logistics were essential due to restricted space between highway traffic, railway tracks, and a stream. Numerous safety and water protection regulations were observed. The Wolffkran team supported site planning and equipped the cranes with slew limiters and cameras to enhance load handling and safety.

Construction involved building a side-position bridge adjacent to the old structure to maintain traffic flow. Once the old bridge was demolished, the new bridge was constructed in its final position. In spring 2025, the deck built in the side position was laterally shifted onto the newly built piers using hydraulics and sliding tracks.

Habau has relied on Wolffkran cranes since 2008. For the Aurach Valley project, the WOLFF 7534.16 Clear’s combination of high load capacity and large freestanding hook height proved decisive.
