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 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 effi ciency
and low operating weight. Thanks to the newly de-
veloped Liebherr Power Effi ciency system the large
wheel loaders use the same amount of fuel com-
pared to their predecessors in the Tier 3 generation.
− Practically no brake wear thanks to the hydraulic
braking action of the driveline; this ultimately reduc-
es repair costs.
− Reduced tire wear due to continuous traction con-
trol. 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.
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.
• Thanks to this technology it was
possible to prevent an increase of
fuel consumption from Tier 3 to Tier
4i. LPE also saves up to an additional
8% in fuel compared to wheel load-
ers where the system is not used.
