tools such as Finite Element
Analysis and Fatigue Life Analysis
Reliability
More than 50 years of hydraulic excavator design and manufacturing experience
is the basis for the R 9400’s outstanding reliability. The machine combines innova-
tive technologies, design optimization and Liebherr components. Customers can
expect durable performance from the R 9400 throughout the machine’s life.
Quality: the Liebherr Trademark
Liebherr Vertical
Integration As an OEM, Liebherr has built a solid reputation for its
development and production of high quality strategic
mining components. The R 9400 integrates robust and

Machine Reliability
Survey Based on years of experience and the systematic mea-
surement of key performance indicators of the machine
behavior in the fi eld, the Liebherr Mining Reliability
Engineering Group is constantly seeking new ways to
enhance reliability.
Quality Management
Continuous Improvement Liebherr quality begins during machine design and simu-
lations. Liebherr meets the highest standards for special
selections of steels and casting materials. Based on the
expertise of certifi ed internal auditors and a highly quali-
fi ed workforce, all manufacturing process steps are de-
vised to provide the most comprehensive control, moni-
toring and traceability. Liebherr-Mining Equipment Colmar
SAS is ISO 9001 certifi ed.
Long-lasting Job Performances
Maximized Compo-
nents Lifetime The R 9400 is equipped with an automatic central lu-
brication system for the entire attachment and swing
ring. All greasing points are suitably protected against
external damages. This extends component life and
ensures constant performance over the excavators’
operational life.
Rugged Undercarriage
Structure The R 9400 is mounted on a heavy duty 3-piece fatigue
resistant undercarriage steel structure. This design pro-
vides better weight distribution of the superstructure and
reduces ground bearing pressure. Designed and built
for both shovel and backhoe confi gurations, the R 9400
provides the necessary stability and reliability.
