Unveiled at ConExpo 2017, Liebherr has extended its mobile crane product range with an additional series of rough terrain cranes in the 90tonne and 100tonne classes.
The new rough-terrain crane LRT 1090-2.1 is said to feature high performance, safety and comfort.
The VarioBase (variable support base) developed by Liebherr, which allows each individual outrigger beam to be extended to optional lengths, is standard on the LRT cranes.
The crane model is powered by a Cummins diesel engine which develops 194kW and supplies a maximum torque of 990Nm.
The LRT cranes are 3.87m high and 3.3m wide, and are transported on public roads with a low loader. Their curb weight is less than 55tonnes with complete equipment including ballast, or under 40tonnes without ballast or equipment.
The LRT 1090-2.1 features a 47m telescopic boom, consisting of a two-stage hydraulic cylinder with a rope extension mechanism.
