 Economy
Compared to conventional transmission, the Liebherr driveline achieves a reduc-
tion in fuel consumption for wheel loaders of 25 % or more! Five litres less fuel per
operating hour significantly reduce operating costs and environmental pollution.

Low operating costs

Minimum costs, Liebherr wheel loaders are unbeatable for econ-
High handling capacity omy compared to conventionally driven wheel
loaders. This is due to the following factors:

− Low fuel consumption thanks to higher effi-

ciency and low operating weight. Liebherr wheel
loaders need up to 5 litres less fuel per operat-
ing hour at the same working conditions.

− More or less no brake wear thanks to the hydrau-

lic braking action of the driveline. This means
there is practically no brake wear and conse-
quent repair costs.

− Reduced tyre wear thanks to continuous trac-

tion control. Depending on the working condi-
tions, there is up to 25 % less wear.

Active environmental protection

Economical use The reduction in fuel lowers emissions, thus
of resources actively protecting resources:
1 litre of fuel produces up to 3 kg of carbon diox-
ide (CO2). By saving up to 5 litres per operating
hour, up to 15,000 kg less CO2 is produced in
1,000 operating hours – that means lower costs
and active environmental protection.
Low noise emission The innovative driveline concept means much
lower noise emission – Liebherr wheel loaders are
significantly quieter in operation.

• Optimum weight distribution thanks
to lengthways-installed Liebherr
diesel engine, output shaft is facing
to the rear.
• The variable displacement pumps
on the engine act as counterweight,
thus allowing higher tipping loads at
low operating weight.
• Compact design improves visibility
in all directions

 Performance
The Liebherr driveline allows the Liebherr diesel engine to be mounted length-
ways in the rear, with the output shaft facing backwards. Compared to conven-
tionally driven wheel loaders, the operating weight is much lower, the tipping
load is higher, and more material can be moved each operating hour.

Higher performance, lower weight

Higher productivity The combination of the Liebherr driveline and the
unique position of the Liebherr diesel engine allows
higher tipping loads at low operating weight. This
leads to significantly higher productivity, because
there is no need for unnecessary counterweight.

Ultra modern Liebherr driveline

Innovative technology The large Liebherr wheel loaders are equipped
with the 2plus2 gearbox. Tractive force and speed
are automatically adjusted to the requirements
of the operator without shifting. There is no need
for a mechanical reverse gear because the travel
direction is changed hydraulically.

Flexibility puts them ahead

An all-purpose loader The Industrial lift arm is the ideal tool to com-
plement the available equipment for the large
Liebherr wheel loaders. Especially when operat-
ing with heavy equipment and loads, this “torque
increase” is the perfect additional system for your
requirements. Their compact design allows these
wheel loaders to maneuver quickly and efficiently
– an ideal basis for high handling capacity.

 Liebherr driveline
• The Liebherr driveline consists of
two hydraulic motors which accel-
erate the loader continuously from
a standstill to maximum speed,
either forwards or in reverse – with
a 2plus2 gearbox – but without a
reversing gear unit.

 Reliability
All the materials used in Liebherr wheel loaders have passed long term tests to
ensure that they meet Liebherr’s exacting standards even in the toughest condi-
tions. The mature concept and proven quality make Liebherr wheel loaders to the
benchmark for reliability.

Reliable Liebherr driveline

Fewer components The Liebherr driveline includes a self-locking
hydraulic brake, which means the additional wet
brake discs are effectively wear-free. There is no
need for a reversing gear unit – thus minimizing the
number of parts susceptible to wear.

Controlled cooling
The intelligent answer The cooling fan is not driven directly from the
Liebherr diesel engine, and produces only the
cooling air output which is actually required.
Heat sensors ensure reliable control. If overheat-
ing should occur, the wheel loader automati-
cally shifts down to first travel speed range. The
reduced power consumption protects the engine
from overheating. At the same time, the fan speed
is increased to maximum value, thus preventing
the engine from overheating.

Components meet manufacturer’s

quality standards
Everything from Important components such as the engine, hydrau-
a single source lic rams and electronics are developed and manu-
factured by Liebherr itself. This ensures co-ordi-
nated quality from the manufacturer down to the
smallest detail. Liebherr components guarantee
maximum performance and reliability.

 Liebherr control lever
• The Liebherr control lever is used to manage all travel and work-
ing movements of the wheel loader, so that the operator’s left
hand can always remain on the steering wheel. There is no need
to let go of the steering wheel, and this increases the safety. The
operator controls the following functions with his right hand:

–
Raise and lower attachment
–
Fill and dump the bucket
–
Automatic bucket return to dig
–
Kick down and Gear Hold function
– Auxiliary control buttons for additional hydraulic functions
–
Change of travel direction with simultaneous travel start

Top-class cabin design

Comfort cab The ultra-modern, ergonomically planned cabin
design allows the operator to achieve better per-
formance and productivity in the greatest possible
comfort. The displays, controls and operator’s seat
are carefully coordinated to form a perfect ergo-
nomic unit.
Liebherr control lever All the working and travel functions are operated
precisely and sensitively from a single control lever.
This means accurate and safe handling, and the left
hand always remains on the steering wheel. This
increases the safety at the job site.

Service access
Easy maintenance Because the Liebherr diesel engine is rotated by
180°, the hydraulic pumps, hydraulic tank, hydraulic

can be reached easily and safely from ground level
by opening a single engine compartment hood. The
engine, pump distributor gear and cooling system
are easily accessible by opening the engine cover.

The Liebherr Standard Consumption Test –

easy to reproduce and practical.
Every Liebherr dealer will provide you with this measuring-tank kit free
of charge or, on request, will carry out the standard fuel consumption
5 test on your premises. It’s so easy: you simply determine the number
of loading cycles that can be carried out with 5 litres of diesel. The
n=?
B
2,5 m

material is taken from pile A and carried over a distance of 20 metres

35 to point B. The time needed for each working cycle should be
35 seconds. Discharge at point B should take place from a height of
4 2.5 m. The working cycles continue until the 5 litres of diesel in the
external measuring tank have been used up. The loader’s fuel con-
30 sumption per operating hour is calculated as follows:
T ~ 35 sec.
