Reliability
More than 50 years of hydraulic excavator design and manufacturing experience
is the basis for the R 9800’s outstanding reliability. The machine combines inno-
vative technologies, design optimization and Liebherr components. Customers
can expect durable performance from the R 9800 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 9800 integrates robust and
reliable mining optimized components that are devel-
oped, manufactured and controlled by Liebherr ensuring
reliability and high performance for the entire machine.
Machine Reliability
Survey Based on years of experience and the systematic
measurement 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
simulations. 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 qualifi ed workforce, all manufacturing process
steps are devised to provide the most comprehensive
control, monitoring and traceability. Liebherr-Mining
Equipment Colmar SAS is ISO 9001 certifi ed.
Long-lasting Job Performances
Maximized Components
Lifetime The R 9800 is equipped with an automatic central
lubrication 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 9800 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 9800 provides the necessary stability and reliability.
