Reliability
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 bench-
mark 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 Liebherr
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 au-
tomatically 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 the diesel engine, hydraulic cyl-
inders and electronics are developed and manufactured by
Liebherr to ensure the highest quality standards. Liebherr
Wheel Loaders are carefully designed down to the small-
est 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 envi-
ronmental compatibility, the new generation of diesel en-
gines 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 l-
tration process ensures effi cient, uninterrupted work.
Liebherr’s own components
• Liebherr has many years of experience
in design, development and con-
struction of diesel engines, hydraulic
cylinders and electronic components.
They are matched together down to the
smallest detail to guarantee optimum
interaction and performance.
Liebherr diesel engine
• Common Rail technology optimizes the
combustion process and thus 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.
