Productivity
An Array of Applications
The integration of the electronic
control system - Litronic Plus -
in combination with the R 9150’s
design optimization enable:
• Maximum machine versatility
• The use of various long reach
attachments and specifi c tools
• To answer the most specifi c
customers requirements
Liebherr Ground Engaging Tools (GET)
Liebherr has developed a complete mining GET
solution to complement Liebherr’s mining back-
hoe and face shovel bucket design. A synergy
that enables easy material penetration while
extending the life of the bucket.
• Three tooth profi les and fi ve tooth sizes
• Innovative bucket lip and side wall
protection
• One single locking system that limits tooling
to one unique extraction tool
• Unique hammerless locking system
• Effortless and quick tooth removal
The brand new R 9150 is built to outperform all competitors in the small class
mining market. As a perfect loader for 50 t up to 135 t dump trucks and offering a
wide array of uses, the advanced R 9150 is the worthy successor of the esteemed
Liebherr R 984 C. As the most powerful excavator in the small mining market, this
machine reaches the highest excavating forces and an optimal cycle time.
Engineered for Intense Mining
Powerful
Drive System The R 9150 is equipped with the long-lasting and
proven Liebherr V12 diesel engine specifi cally
designed to withstand extreme outside temperatures
and high altitudes with low atmospheric pressure.
Integrating the latest engine management system, the
R 9150 is built for intense mining.
Fast Cycle Times Rather than using open hydraulic circuit, the R 9150 em-
ploys a closed-loop swing circuit to enable maximum
swing torque while retaining the full oil fl ow for the work-
ing circuit. The independent swing circuit in combination
with the powerful drive system leads to fast arm motion,
which contributes to faster cycle times.
Precise Machine
Motions The R 9150 design integrates the Litronic Plus electronic
control system to allow for easy control even when simul-
taneous movements are required. The patended Liebherr
electronic bucket cylinder damping system provides con-
trolled end-cushioning for smooth attachment motions.
High Digging and Lifting Capabilities
High Digging Forces Designed for the best mechanical force distribution, the
production-tailored attachment delivers high digging and
lifting forces. Integrating Liebherr-made cylinders and a
wide range of buckets with mining-optimized GET, the
R 9150’s attachment ensures the highest forces, easy
bucket penetration and high fi ll factor to perform even in
the most demanding conditions.
Power-Oriented
Energy Management The R 9150’s attachment is equipped with the pres-
sureless boom down function to enable fast cylin-
der retraction without the need for pump energy.
Intelligent energy management diverts the pump fl ow
during boom lowering, allowing other cylinder
motions to operate unimpeded.
