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 Power Effi 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.
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!
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.
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 (CO
2
).
By saving up to 1.3 gal per operating hour, up to 33,070 lb
less CO
2
is produced in 1,000 operating hours. Not only
are operating costs reduced but the environment also
benefi ts from the drastically reduced emissions.
Low noise emission The innovative driveline concept means much lower noise
emission – Liebherr wheel loaders are signifi cantly quieter
in operation.
