Liebherr achieved the milestone of 100 units of the 750-tonne LTM 1750-9.1 mobile crane. The 100th crane of this type left the plant in Ehingen in July this year. The new crane was handed over by Liebherr?s Belgian dealer Van Der Spek to crane contractor Dufour Transports et Manutention SA based in Marquain, Belgium. The LTM 1750-9.1 will be a new addition to and the largest mobile crane in the company?s fleet. The key feature of Liebherr?s 9-axle machine is that the entire telescopic boom can be conveyed on public roads.

For its first job, the LTM 1750-9.1 travelled to Aisne in France where it helped to erect a 2.75 MW wind turbine. Its compact dimensions and massive hoisting capacity were major benefits for this job.

The LTM 1750-9.1 has been successful on all five continents. There are 59 cranes in Europe, 22 in America, 16 in Asia, two in Africa and one in Australia. The 9-axle machine features the latest mobile crane technology and includes Liebherr innovations such as VarioBase? and ECOmode. With a maximum axle load of 12 t, the LTM 1750-9.1 can carry its 52 m telescopic boom, front support outriggers, an auxiliary support cylinder at the rear and a complete hoist winch.

With its Y telescopic boom guying and a very wide range of lattice jibs, the LTM 1750-9.1 has a large number of boom systems. These enable it to achieve hoist heights of up to 154 m and radii of up to 112 m. The luffing lattice jib can be assembled in 3.5 m stages up to a total of 91 m.
