Liebherr returns to rough terrain crane market
Liebherr has begun making rough terrain cranes for the first time in decades.
Since the 1980s Liebherr’s mobile crane production in Ehingen, Germany, has been focused on the all terrain type, which can drive on highways as well as construction sites.
However, in a substantial strategy shift, it has now decided to re-enter to rough terrain crane market, which remains an active segment outside of Europe, particularly in the USA and the Middle East and Asia.
Liebherr will launch the LRT 1090-2.1 (rated at 90 tonnes capacity) and the LRT 1100-2.1 (100 tonnes) at the Conexpo construction machinery trade show in Las Vegas in March 2017. They are powered by Cummins engines, not Liebherr’s own.
The two models differ only in boom length, telescoping technology and ballast weight.
The cranes have Liebherr’s VarioBase variable outrigger monitoring system as standard. However the outriggers are setup, if at all, results in the crane’s computer automatically adjusting lifting capacity to prevent it overturning.
The LRT 1100-2.1 has a 50-metre 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. It has 14 tonnes of counterweight.
The 90-tonne model has 12 tonnes of counterweight and a 47-metre telescopic boom that consists of a two-stage hydraulic cylinder with a rope extension mechanism.
