In Germany, Nolte Auto-Kran used its Liebherr LG 1750 to erect what is claimed to be the highest wind turbine in the world. The lattice tower that would house the turbine stood at 160 m high, weighed 350 tonnes and was located at Laasow, near the city of Cottbus.

The crane was configured with a 91 m main boom, 77 m of luffing jib, a 31.5 m derrick and 225 tonnes of counterweight to complete the erection of the turbine.

The heaviest and highest lift of the erection was the placing of the 61 tonne machinery house, which had to be hoisted to just over 160 m at a radius of 35 m. •
