Photographs of Schmidbauer’s Liebherr LR 11350 Crawler Crane in the Alps

The Charmaix Viaduct in the Auvergne-Rhône-Alpes region, built in 1978, had to be replaced due to structural problems.

Last summer, the new structure, which runs parallel to the A43 motorway, was opened to traffic and work began on dismantling the old bridge. In autumn, the most powerful crawler crane from German crane and heavy-duty contractor Schmidbauer GmbH & Co. KG then lifted the last girders off of the highest pillars.

The challenges involved in assembling the Liebherr crawler crane on the mountainside were immense.

 

Made of steel – is the 18 tonne hook block of the LR 11350. Perhaps also the Schmidbauer crew, who did the arduous job in the French mountains with aplomb. Image featuring: Oliver Thum, External Technical Team (right) and crane driver Fabian Ueck.

 

Routined & focussed – Frank Wache at the controls has one of the old girders on the hook, which he now has to set down on the scree slope. The powerful teeth of the excavators then finish off the mighty reinforced concrete trusses on the ground.

 

Overview – The LR 11350 has already emptied the first of the three truss bays here with its lattice boom over 100 metres long. Two others are waiting to be dismantled after 45 years of service. The bird’s eye view illustrates how cramped the usable space is for the large crawler crane. A few metres away, the new viaduct is already carrying traffic.

 

Huge and weighty – are the lifting means between the hook block and the load. High above the valley, the men heave these thick, sheathed steel cables over the hooks. Here, Simone Agostinetto (left) from the Dutch heavy haulage company Mammoet assists with the attachment of the next girder. Mammoet was responsible for the crane work during the dismantling of the viaduct. As the Dutch company did not have a suitable crawler crane in its own fleet for this bridge dismantling project, the LR 11350 from Schmidbauer was booked.

 

 

The crane and the Schmidbauer team spent around three months working in the Alps. By mid-December, the old viaduct had disappeared.
