Economy

The Liebherr driveline with Liebherr Power Effi ciency (LPE)
reduces wheel loader fuel consumption by 25 % or more when
compared to conventional travel gears!

Performance

The Liebherr driveline allows for optimal positioning of the diesel
engine. In this wheel loader class the diesel engine is rotated 90°
and mounted transverse to the direction of travel. 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.

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
benchmark of reliability.

Comfort

The ultra-modern cab design with advanced ergonomics
continuously variable Liebherr driveline for uninterrupted
tractive force, optimum weight distribution and easy service
access lead to extraordinary overall comfort.

Low operating costs

Minimum costs,
high handling capacity

When it comes to economy, conventional wheel loaders
are no match for Liebherr machines, mainly due to the
following factors:

− Low fuel consumption thanks to higher effi ciency and
low operating weight. Thanks to the newly developed
Liebherr Power Effi ciency system the generation
Tier 4i wheel loaders L 524 – L 542 use up to 8 % less
fuel compared to their predecessors.

− Practically no brake wear thanks to the hydraulic braking
action of the driveline; this ultimately reduces repair
costs.

− Reduced tire wear due to continuous traction control.
Depending on the working conditions, there is up to
25 % less wear.

Liebherr Power Ef fi ciency (LPE)

• The newly developed system known
as Liebherr Power Effi ciency (LPE)
optimizes the interaction between
the drive components. It optimizes
the position of the working point in
the characteristic map with regard
to the degree of effi ciency.

• LPE saves up to an additional 8 %
in fuel compared to wheel loaders
where the system is not used.

Active environmental protection

Economical use
of resources

Low noise emission

The reduction in fuel lowers emissions, thus actively
protecting resources:

0.3 gal of fuel produces up to 7 lb of carbon dioxide (CO
By saving up to 1.3 gal per operating hour, up to 33,070 lb
less CO

is produced in 1,000 operating hours. Not only
are operating costs reduced but the environment also
benefi ts from the drastically reduced emissions.

The innovative driveline concept means much lower noise
emission – Liebherr wheel loaders are signifi cantly quieter
in operation.

Reduced tire wear

• The tractive force can be adjusted
continuously. This stops wheel spins
and reduces tire wear by up to 25 %.

Reduced brake 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.

Liebherr driveline

• Optimum weight distribution

• The diesel engine as well as the
variable displacement pumps
mounted on the engine act as
counterweight, therefore allowing
higher tipping loads at low

Performance

The Liebherr driveline allows for optimal positioning of the diesel engine. In this wheel
loader class the diesel engine is rotated 90° and mounted transverse to the direction of
travel. 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.

Power All-Rounders
for industry

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

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.

The parallel linkage is available as an alternative to the standard
Z-bar linkage, at no additional cost. The parallel linkage features
a parallel guide arrangement and high torque in the upper lifting
range - ideal properties for larger and heavier attachments
as well as transporting heavy loads. With its parallel linkage
Liebherr offers a continuous and uniform solution for industrial
operations over the entire range of all-round loaders. With their
compact design, Liebherr wheel loaders can maneuver quickly
and effi ciently - the best choice for high handling capacities.

The new generation Tier 4i all-round wheel loader models have
been specifi cally developed for industrial use in terms of their
performance and stability and ensure even higher productivity
and effi ciency. In addition to increasing the engine performance,
the tipping loads of the whole range have been increased.
Furthermore the steel structure has been reinforced and the
hydraulic system‘s performance enhanced. That, together with
the wide range of equipment available makes these all-round
loaders the perfect solution for all industrial uses.

Conventional travel gear

• Longitudinally mounted diesel
engine moves the center of gravity
further forward.

• Much more additional
counter weight is needed to maintain
stability and to increase the tipping
load.

• This leads to high operating weight
and poor visibility.

An all-purpose loader

• The choice between parallel (P) and
Z-bar linkage means that the loader
can always be confi gured to suit
the customer’s specifi c tasks: P for
industrial use, Z for conventional
material handling.

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 – without a manual gear
shift and a reversing gear unit.
