Liebherr has extended its mobile crane product range with an additional series of rough-terrain cranes in the 90-tonne (100 USt) and 100-tonne (110 USt) classes.

The 100-tonne (110USt) LRT 1100-2.1 has a 50 m (164ft) telescopic boom with a “Telematik” telescoping system on which the various telescoping sections can be extended independently with a single cylinder and then pinned to the telescopic section above. The telescoping system on the new rough-terrain crane is particularly simple and user-friendly as excellent lifting capacities over the entire radius range can be achieved with just two telescoping modes, Strong or Long. 14 tonnes (30,800 lbs) of counterweights ensure high stability. The lifting capacity of the LRT 1100-2.1 is around 15% higher than that of the 90-tonne (100 USt) model which features 12 tonnes (26,500 lbs) of counterweights.
