The maximum lifting capacity of a Liebherr all-terrain crane, combined with the longest telescopic boom in the world. Furthermore, various lattice extensions are available for the boom. The 9-axle chassis includes the active, speed-dependent rear-axle steering we developed. Significant increases in lifting capacities are generated using Y-guying on the telescopic boom. With its long telescopic boom, Y-guying and easily installed lattice extensions, the LTM 11200-9.1 is ideal for erecting wind turbines. The setup times are significantly shorter than lattice boom cranes and comparatively low counterweights and space are required to erect the boom. Its different driving configurations enable this all-terrain crane to be transported at low cost all over the world.
