Liebherr, one of the world’s leading manufacturers of mobile and crawler cranes, has unveiled the new LG 1800-1.0, combining the advantages of a mobile crane with the load capacity of a lattice boom crane

The new offering is the successor to the Liebherr LG1750 lattice boom crane, previously one of the most powerful cranes of its kind on the market, and will be launched in the first half of 2024 under the motto “The legend grows”

Capable of lifting up to 800 tonnes (just as much as its crawler crane counterpart, the LR 1800-1.0), the LG 1800-1.0 features state-of-the-art crane technology such as V-Frame, VarioTray, ZF Traxon Torque transmission with ECOdrive and WindSpeed load charts. 

According to Liebherr, the new machine is cut out for all markets and is suitable for public roads worldwide. This is due to its unique chassis with a special arrangement of axles and an axle load of just 10 tonnes.

Other notable highlights include folding beams, not telescopic; a quick coupling system enabling fixed supports to be easier to attach and detach; one more axle that its predecessor; and a chassis width of just 3 m enabling it be moved economically on road and construction sights (it can even cope with gradients of up to 25%) making it particularly effective when working in wind farms. 

The LG 1800-1.0 can adopt the familiar boom systems of the LR 1800-1.0. There is both a main boom up to 180 m long and a main boom luffing jib combination with up to 108 m of main boom and 102 m of luffing jib, with which a maximum hook height of 208 m can be achieved. Thanks to optimised wind power boom systems, it is possible to work with a boom of 174 m and an 18 m-long lattice type fixed jib at hub heights of 180 m. The ‘WindSpeed Load Charts’ with different permissible wind speeds of up to 13.4 m/s also ensure increased flexibility and safety in gusty operating conditions.

Indeed, according to Liebherr, all the equipment of the LG 1800-1.0 is compatible with the equipment of the LR 1800-1.0 and all accessories from the head section to the lattice type fixed jibs and whip line are identical. All boom systems have the same designation as the LR 1800-1.0. The ten-tonne counterweight plates can also be used for other Liebherr crawler cranes. The only difference compared to the LR 1800-1.0 is a modified slewing platform that allows longer boom systems to be erected without a derrick.
