The LTM 1750-9.1 is now the largest Liebherr mobile crane in the Dufour fleet.

“The key feature of Liebherr's nine-axle machine is that the entire telescopic boom can be conveyed on public roads,” Liebherr said.

A reason behind Dufour’s decision to purchase this crane was the “enormous” increase of orders from the wind power sector and the reliability of the manufacturer’s cranes.

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.

Liebherr said: “The LTM 1750-9.1 has been successful on all five continents. There are 59 cranes in Europe, 22 in America, 16 in Asia, 2 in Africa and 1 in Australia. The nine-axle machine features the very latest mobile crane technology and includes Liebherr innovations such as VarioBase and ECOmode. With a maximum axle load of 12t, 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 112m. The luffing lattice jib can be assembled in 3.5m stages up to a total of 91m.
