Bauma 2007: premiere of the world’s most powerful telescopic crane
One of the highlights at the Liebherr stand at Bauma 2007 is the new LTM 11200-9.1 all-terrain crane. This entirely newly developed nine-axle crane with a maxmum lifting capacity of 1,200 tons is not only the most powerful telescopic crane in the world; it also surpasses all others with its 100-m telescopic boom. The eight-part boom on this new flagship model is 16 m longer than the previous record holder, the LTM 1500-8.1, which Liebherr presented for the first time at Bauma 1998.
The 100-m telescopic boom consists of a base section and seven telescopic parts. The different extended lengths are fully automatically positioned and locked in place using the tried-and-tested rapid-action TELEMATIK telescoping system. Alternatively, a four-part ‘short’ telescopic boom can be used with the four inner telescopic parts extended. This principle has already proved itself on the LTM 1500-8.1. A radius of 55 m is achieved with the help of a 3-m lattice head section.
Numerous lattice extensions are also available. The luffing fly jib can be extended to 126 m and reaches lifting heights of up to 170 m. The Y-shaped guying system on the telescopic boom, which can be used on either the four- or eight-part boom, offers remarkable increases in load capacity.
