German crane services company Kran-Maier GmbH have enacted a 44-tonne lift at the Deutsches Museum in Munich, Germany.
Completed as part of renovation work at the museum, a Liebherr LTM 1250-5.1 mobile crane was used to shift an impeller of a Francis turbine – an inward-flow reaction turbine combining radial and axial flow concepts primarily used for electricity.
Taking place in mid-May, the impeller that was dismantled was 80 years old and occurred in “challenging” conditions according to Managing Director of Kran-Maier Susanne Maier.
“In addition to the partly sloping museum garden, the traffic conditions in Munich were also challenging – narrow bridges and narrow streets filled with parked cars required special skill on the part of our drivers,” she said. “But thanks to the compactness and active rear axle steering of the LTM 1250-5.1, that wasn’t a problem either.”
A further feature of Liebherr’s mobile crane that allowed for an increase in safety was its variable VarioBase support. With a practical interface, the system allows the operator to concentrate on what matters most: ensuring the safe and efficient handling of their load.
Featuring a 60-metre telescopic boom and a maximum hoisting height of 108 metres, Liebherr’s five-axle mobile crane excels in constricted sites thanks to its VarioBallast, which can go up to 88 tonnes.
Also capable of using HVO fuel, the LTM 1250-5.1 also possesses ECOmode and ECOdrive technologies that ensure its efficient and operation.
