Liebherr LG1750 is a lattice-tower mobile crane, with a 750 tonnes lifting capacity class. The LG1750 comes with an 8 axles chassis and the superstructure is based on Liebherr very own crawler crane, LR1750. The crane is also equipped with four rigid, folding outriggers in an X pattern, creating a base area of 16 x 16 metres for stability.

New SL12D2FB Boom System
The new boom system enables the LG1750 to erect new large types of wind power systems at tower heights from 140 to 150 metres. The design was derived from the former successful SL9D2FB boom, the main boom arrangement with fixed jib and derrick system. One of the changes was the use of three stronger 12 metres lattice boom with a width of 3.5 metres instead of 3.0 metres in the lower section of the main boom, and by lengthening of the fixed jib, the new SL12 system increases the load capacity and height under the hook. The LG1750 can achieve a greater load capacity of 141 tonnes at a height under hook of 143 metres and 97 tonnes at 160 metres.
