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 Compo-
nents Lifetime The R 9150 is equipped with an automatic central lubri-
cation system for the entire attachment and swing ring.
All greasing points are suitably protected against external
damages. This extends component life and ensures con-
stant performance over the excavators’ operational life.
Rugged Undercarriage
Structure The R 9150 is mounted on a heavy duty fatigue-
resistant undercarriage. The swing ring is reinforced
to provide an improved superstructure weight
distribution. Designed and built for both shovel and
backhoe confi gurations, the enlarged undercarriage
offers an effi cient ground bearing pressure repartition
providing the necessary stability and reliability.
