A 1,200t Liebherr LTM 11200-9.1 telescopic boom has been used to install a wind power plant in Germany.
Crane company Karl Hartinger Kranbetrieb, based in Warburg-Rimbeck, used a nine-axis LTM 11200-9.1 to install a 3MW Enercon E-101 wind energy plant in Preussisch Oldendorf, in the north-west of Germany.
The heaviest part of the plant was the machine housing, which had to be mounted to a hub height of 99m, with the total load including lifting gear and hook block at 66.5t.
The telescopic boom with Y-pattern guying was extended to 82m, mounted with a 31.6m lattice jib. The LTM 11200-9.1 also features a 6.5m-long hydraulic luffing lattice jib, which was well-suited to the project.
Karl Hartinger crane operator Tjerk Thomiczek said: “The hydraulically luffable lattice jib is unbeatable on this crane, because I can set up the entire E-101 from a single position. I never have to reposition – that’s a huge advantage. Over the course of the installation, the extension was reduced from 19m to about 10m.”
