Rollout of the new Telescopic-Crawler Crane LTR 11200
The prototype of the new telescopic crawler crane LTR 11200 recently moved out of the newly constructed assembly shop for large cranes at the Liebherr factory in Ehingen. A special delight for the Liebherr employees who were involved in the design and manufacturing – as well as some customers from the field of erection of wind power plants was, that the family shareholder Dr. h.c. Dipl.-Ing. (ETH) Willi Liebherr made a speech for the official rollout of the new 1200-ton crane. He emphasized the importance of the wind power as the main operational area for the new LTR 11200.
The 100 m telescopic boom and to a large extent also the slewing platform were adopted from the mobile crane LTM 11200-9.1, which has proved itself numerous times at erections of wind power plants. On suggestion of the wind power plant manufacturer Enercon Liebherr developed the concept of a telescopic crawler crane on a narrow track crawler chassis, which is optimized for the driving of the crane in assembled state on the narrow roads in wind parks. The crawler width amounts to a maximum of only 4,8 m. For the crane operation the LTR 11200 is supported on a star support with a basis of 13 m x 13 m. The boom systems with Y-suspension as well as the fixed and luffing lattice fly jibs well known from the LTM 11200-9.1 are also incorporated in the crawler version of the 1200-ton crane.
