Economy
Reliability
The Liebherr driveline reduces wheel loader fuel consumption by 25 % or more when compared to conventional travel gears! Liebherr wheel loaders save up to
1.3 gallons of fuel per operating hour, significantly reducing operating costs and environmental pollution.
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 conditions. The mature concept and proven quality make
Liebherr wheel loaders the benchmark for reliability.
Performance
Comfort
The Liebherr driveline allows the Liebherr diesel engine
to be mounted lengthways in the rear, with the output
shaft facing backwards. Compared to conventionally
driven wheel loaders, the operating weight is much
lower, the tipping load is higher, and more material can
be moved each operating hour.
The ultra-modern cab design with advanced ergonomics, continuously variable Liebherr driveline with 2plus2
gearbox for uninterrupted tractive force, standard
Liebherr ride control, optimum weight distribution and
easy service access due to unique engine installation
position lead to extraordinary overall comfort.

Economy
The Liebherr driveline reduces wheel loader fuel consumption by 25 % or more
when compared to conventional travel gears. Liebherr wheel loaders save up to
1.3 gallons of fuel per operating hour, significantly reducing operating costs and
environmental pollution.
Low operating costs
Minimum costs,
High handling capacity
Liebherr wheel loaders are unbeatable for economy compared to conventionally driven wheel
loaders. This is due to the following factors:
− Low fuel consumption thanks to higher efficiency
and low operating weight. Liebherr wheel loaders consume up to 1.3 gallons fuel per operating hour less than conventionally driven wheel
loaders in the same working conditions.
− Practically no brake wear thanks to the hydraulic braking action of the driveline; this ultimately
eliminates consequent repair costs.
− Reduced tire wear due to continuous traction
control. Depending on the working conditions,
there is up to 25 % less wear.
Active environmental protection
Economical use
of resources
The reduction in fuel lowers emissions, thus
actively protecting resources:
0.3 gal of fuel produces up to 7 lb of carbon
dioxide (CO2). By saving up to 1.3 gal per operating hour, up to 33,069 lb less CO2 is produced
in 1,000 operating hours. Not only are operating
costs reduced but the environment also benefits
from the drastically reduced emissions.
Low noise emission
The innovative driveline concept means much
lower noise emission – Liebherr wheel loaders are
significantly quieter in operation.
Reduced brake wear
Reduced tire wear
• Even under the toughest working conditions, the Liebherr travel drive always
brakes hydraulically. The mechanical
service brake only acts as a support and
is therefore subject to hardly any wear.
• The tractive force can be adjusted continuously. This stops wheel spins and
reduces tire wear by up to 25 %.

Liebherr driveline
• Optimum weight distribution thanks to
lengthways-installed Liebherr diesel
engine, output shaft is facing 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 lengthways in the rear, with the output shaft facing backwards. Compared to conventionally 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 driver 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 Lumberjack is the ideal tool to complement the
available equipment for the large Liebherr wheel
loaders. This „torque increase“ is the perfect additional system for your requirements, especially
when operating with heavy equipment and loads.
Their compact design allows these wheel loaders to maneuver quickly and efficiently – an ideal
basis for high handling capacity.
Conventional travel gear
An all-purpose loader
• Longitudinally mounted diesel engine
moves the center of gravity further forward
• The choice between Lumberjack
or Z pattern linkage means that the
loader can always be configured for
every job application – Lumberjack
for industrial use; Z for conventional
material handling.
• Additional counterweight is needed to
maintain stability and to increase the
tipping load.
• This results in high operating weight
and bad visibility
L 550 2plus2 – L 586 2plus2

Liebherr driveline
• The Liebherr driveline consists of
two hydraulic motors which accelerate 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 conditions. The mature concept and proven quality make Liebherr wheel loaders 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 overheating should
occur, the wheel loader automatically 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
a single source
Important components such as the engine, hydraulic rams and electronics are developed and manufactured by Liebherr itself. This ensures co-ordinated quality from the manufacturer down to the
smallest detail. Liebherr components guarantee
maximum performance and reliability.
Cooling system
Liebherr’s own components
• The cooling system is fitted on the rear section between the diesel engine and the operator’s cab. The cooling air is drawn in directly
behind the cab and blown out upwards at the
rear. The fan speed is varied automatically by
heat sensors that determine the amount of
cooling needed.
• Liebherr has many years of experience in
design, development and construction of
diesel engines, hydraulic rams and electronic
components. They are matched together
down to the smallest detail to guarantee
optimum interaction and performance.
• A reversible fan drive to expel dust from the
radiator can be specified as an optional extra.

Liebherr control lever
• The Liebherr control lever is used to manage all travel and working 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 increasing overall 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

Comfort
The ultra modern cab design with advanced ergonomics, continuously variable
Liebherr driveline with 2plus2 gearbox for uninterrupted tractive force, standard
Liebherr ride control, optimum weight distribution and easy service access due
to unique engine installation position lead to extraordinary overall comfort.
Top-class cabin design
Comfort cab
The ultra-modern, ergonomically planned cabin
design allows the operator to achieve better performance and productivity in the greatest possible
comfort. The displays, controls and operator’s seat
are carefully coordinated to form a perfect ergonomic 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.
Liebherr driveline
Continuously variable
transmission
The Liebherr driveline with its 2plus2 gearbox
allows continuous regulation of acceleration in all
speed ranges, without noticeable gear shifting or
interruption in tractive force.
Service access
Easy maintenance
Because the Liebherr diesel engine is rotated by
180°, the hydraulic pumps, hydraulic tank, hydraulic
tank cut-off valve, air filter and battery main switch
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.
Hydrostatic fan drive
The cooling system is positioned directly behind
the cab, which means there is less dirt and therefore less maintenance and cleaning resulting in time
and cost savings!
Service access
Powerful air-conditioning system
• The unique position of the Liebherr diesel
engine provides perfect accessibility for maintenance. The hydraulic pumps, hydraulic tank,
hydraulic tank cut-off valve and battery main
switch can be easily and safely accessed from
ground level by opening a single engine compartment hood.
• The standard equipped air-conditioning system
of the large wheel loaders provides the greatest
operator comfort for high productivity.
• The air flow is controlled at 4 different levels
– an automatic air-conditioning system is available as an option.
– Air flow in the feet area
– Defroster
– Air flow in the head area
– Air flow in the body area

Tipping Load
ISO
7546
What is tipping load?
Load at center of gravity of working equipment, so that the wheel loader just begins to
tip over the front axle.
This the most unfavorable static-load position
for the wheel loader.
Lifting arms horizontal, wheel loader fully
articulated at center pivot.
Pay load.
The pay load must not exceed 50 % of the
tipping load when articulated.
This is equivalent to a static stability-margin
factor of 2.0.
Bucket capacity.
The bucket volume is determined from the
pay load.
Tipping load, articulated
Pay load =

The Liebherr Standard Consumption Test –
easy and practical to reproduce.
Every Liebherr dealer will provide you with this measuring tank kit free
of charge or, on request, will carry out the standard fuel consumption
test on your premises. It’s so easy: you simply determine the number
of loading cycles that can be carried out with 1.3 gal/5 liters of diesel.
The material is taken from pile A and carried over a distance of 22 yd/
20 m 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
8 ft/2.5 m. The working cycles continue until the 1.3 gal/5 liters of
diesel in the external measuring tank have been used up. The loader’s
fuel consumption per operating hour is calculated as follows:
