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.

Key technologies –
