Reliability
Liebherr provides customers with solutions that lead the way for the future,
solutions for maximum equipment reliability and availability, solutions which
satisfy the most extreme demands for performance and quality. With more than
50 years experience in the construction of hydraulic excavators, we have an
advantage in design and consultation that clearly sets us apart.
High stability undercarriage
Better force distribution The undercarriage concept leads to increased per-
formance with improved service life. Thanks to the
connection of the middle section being extended as
far as the ends of the chassis beams, known as the
X-design, the forces are better distributed, which
increases the service life of the undercarriage.
Technology with perspective
Quality right down
to the last detail
The at-a-glance layout of the hydraulic, lubrication,
and electricity lines makes for optimum functional
reliability and maximum availability of the unit. Best
possible corrosion protection is guaranteed thanks
to components and modules being finalpainted and
surface treated before assembly.
Perfect optimisation Individual components of the drive train, manufac-
tured in-house, such as diesel engine, traction drive,
rotary actuators, operating pump and hydraulic
cylinder are perfectly optimised with one another.
As components of a total system designed for long
operational life, they guarantee maximum possible
reliability.
Safety of functionality
Safety of functionality
ROPS cab structure
The cab is equipped with an integrated roll-over
protection system (ROPS) in accordance with
ISO 12117-2, guaranteeing driver safety in any
situation.
Automatic control
of functionality
The operator can entirely focus on his job, be-
cause the integrated on-board electronic continu-
ously performs a comparison with pre-determined
target data. Eventual deviations from the target
parameters are shown on the display.
