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 special casting
materials. Based on the expertise of certifi ed internal
auditors and a highly qualifi ed workforce, all manufac-
turing process steps are devised to provide the most
comprehensive control, monitoring and traceability.
Long-lasting Job Performances
Maximized
Component Lifetime
The R 9100 is equipped with a single line centralized
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 9100 is mounted on a heavy duty fatigue-
resistant undercarriage and is equipped with the over-
sized proven track chain system from heavier Liebherr
excavators. Designed and built for both shovel and
backhoe confi guration, the R 9100 provides the
necessary stability and reliability.
