5 R 9100
Liebherr Ground Engaging Tools (GET)
The new Liebherr Mining GET range is
fully in line with the Liebherr buckets
design, a synergy that enables easy
material penetration while extending
bucket steel structure lifetime:
• 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
Liebherr Site-Specifi c Bucket
• 4 to 5 passes to load a 50 t dump
truck
• Three types of wear package
• Maximal bucket fi ll factor
• Integrated approach on machine
capabilities
• Light weight bucket for max.

Productivity
Effi cient and effective by design, the R 9100 sets a new standard in job
performance and functions as the optimal tool for loading 50 t up to 100 t dump
trucks. Offering a high level of versatility the R 9100 opens up new opportunities
for a wide range of excavating applications.
Engineered for Intense Mining
Powerful Drive System The R 9100 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 9100 is built for intense mining.
Optimized Cycle Times Rather than using open hydraulic circuit, the R 9100
employs a closed-loop swing circuit to enable
maximum swing torque while retaining the full oil
fl ow for the working circuit. The independent swing
circuit in combination with the powerful drive system
leads to fast arm motion, which contributes to faster
cycle times.
Easy Machine Control The R 9100’s hydraulic control system is optimized
in order to improve combined machine motions. The
ergonomically mounted joysticks on the suspended
seat armrests allow the operator to precisely position
the machine.
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 9100’s attachment ensures the
highest forces, easy bucket penetration and high fi ll fac-
tor to perform even in the most demanding conditions.
Power-Oriented
Energy Management The R 9100’s attachment is equipped with the
pressureless boom down function to enable fast
cylinder 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.
