24.09.2014 Liebherr LTM 11200-9.1 mobile crane installs Enercon E-101 wind power plant
- Crane specialist Hartinger relies on 1200-tonner from Liebherr
- 63-ton machine housing mounted at 99 m hub height
- Hydraulically adjustable lattice jib does the job in practical applications
Karl Hartinger Kranbetrieb GmbH & Co. KG in Warburg-Rimbeck, North Rhine-Westphalia relies on 1200-ton telescopic cranes from Liebherr. For lifting tasks that are usually carried out using lattice boom cranes, Hartinger uses the strong, flexible LTM 11200-9.1 and LTR 11200 telescopic cranes. In particular in the installation of wind power plants, this has proved to be very practical.
Recently, Hartinger used the 9-axis LTM 11200-9.1 in Preussisch Oldendorf to install the 3 MW Enercon E-101 wind energy plant. The heaviest part, the machine housing, had to be mounted at a hub height of 99 m. The gross load including the lifting gear and hook block came to a total of 66.5 tons. The telescopic boom with Y-pattern guying was extended out to 82 m in length and a 31.6 m lattice jib mounted on it.
The hydraulically luffable top part, the 6.5 m long luffing lattice jib, also came in handy for this job. Crane operator Tjerk Thomiczek enthuses: "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 namely reduced from 19 m to about 10 m." The hydraulic luffing jib also permits particularly fine changes in outreach. That's especially important when installing elements at extreme heights.
Other advantages of the Liebherr LTM 11200-9.1 and LTR 11200 telescopic cranes are their short set-up times and their small footprint on the construction site. Moreover, comparatively little ballast needs to be transported to the work site. When setting up the E-101, the LTM 11200-9.1 required only 102 tons of ballast.
