The prototype of the 1,200 tonne capacity Liebherr LTR 11200 telescopic boom crawler has been shown to buyers in the wind turbine industry. It moved out of the new assembly shop for large cranes at the Liebherr factory in Ehingen, Germany in March.

Marking the occasion for the Liebherr employees involved in the design and manufacture and for customers in the wind turbine erection industry was that family shareholder Dr. Willi Liebherr made a speech at the official unveiling event. Liebherr emphasised the importance of wind power as the main application area for the new crane.

The new crane uses the 100 m telescopic boom and, to a large extent, the slewing platform from the wheeled mobile LTM 11200-9.1, also used for erecting wind turbines. For crane operation the LTR 11200 is supported on a star pattern outrigger base 13 x 13 m. Boom attachments are available from the wheeled version, including the Y-suspension system and fixed and luffing lattice fly jibs.

At the suggestion of wind turbine manufacturer Enercon, Liebherr developed the concept of a telescopic crawler crane on a narrow track crawler chassis. The idea is that the narrow track allows the assembled crane to be driven on the narrow roads of wind farms. Crawler width is 4.8 m.
