Reliability
Diesel engine
• Common Rail technology optimizes the
combustion process and reduces emissions.
• Further reduction of particle emissions due to
the diesel particle fi lter with oxidation catalytic
converter. Active regeneration ensures effi cient,
uninterrupted work.
• Proactive intervention of Liebherr Power
Effi ciency (LPE) in the engine management
system increases effi ciency.
Cooling system
• The radiator is installed on the rear
section of the vehicle, between the
diesel engine and the cabin. Cooling
air is drawn in directly behind the
cabin and blown out upwards at
the rear. The fan speed is varied
automatically by heat sensors that
determine the amount of cooling
needed.
• The reversible fan drive is
a standard feature.
All the materials used in the Liebherr wheel loaders have passed extensive tests to ensure
that they meet Liebherr’s exacting standards even in the toughest conditions. The advanced
concept and proven quality make Liebherr wheel loaders the benchmark of reliability.
Reliable Liebherr driveline
Fewer components The Liebherr driveline includes a self-locking hydraulic
brake, which means the additional wet brake discs are
wear-free since there is no need for a reversing gear unit.
There are fewer components needed, which minimizes the
number of parts susceptible to wear.
Controlled cooling
The intelligent
answer The cooling fan is driven independently from the diesel
engine and produces only the cooling air output which is
actually required. Heat sensors ensure reliable control. If
overheating should occur, the wheel loader automatically
shifts down to fi rst travel speed range. The reduced power
consumption protects the engine from overheating. At the
same time, the fan speed is increased to maximum output,
thus preventing the engine from overheating.
Components meet manufacturer’s quality
standards
Everything from
a single source Main components such as hydraulic cylinders and
electronics are developed and manufactured by Liebherr
to ensure the highest quality standards. Liebherr Wheel
Loaders are carefully designed down to the smallest detail
to provide customers with the perfect machine solution to
match the application-specifi c demands while achieving
maximum productivity and longevity.
Optimized engine
technology As well as further developments towards greater
environmental compatibility, the new generation of diesel
engines have been optimized in a number of other respects.
In addition to Common Rail technology a diesel particle
fi lter signifi cantly reduces exhaust emissions. With active
regeneration, in most operational circumstances this
fi ltration process ensures effi cient, uninterrupted work.
