5 R 984 C
Compact Machine Design
Liebherr’s excavator design is
well-balanced and provides best
machine stability enabling:
• High weight distribution towards
the undercarriage
• Effi cient utilization of the strong
digging forces
• Favorable power to weight
ratio of the uppercarriage
and attachment
• Fast cycle times
Liebherr Ground Engaging Tools (GET)
Liebherr has developed a complete mining
GET solution to complement Liebherr’s mining
backhoe 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
Productivity
The R 984 C mining excavator is the most fl exible digging and loading tool. It can
be customized for all mining applications for maximum performance. Even under
the hardest conditions, it achieves high productivity. Always ready for job, the
R 984 C is your key tool to reach the expectations.
Engineered for Intense Mining
Optimized Cycle Times Rather than using open hydraulic circuit, the R 984 C
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.
Powerful Drive System The R 984 C is equipped with a Cummins diesel
engine which has been specifi cally adapted to
withstand the most extreme environments and to
reach the highest uptime performance for maximum
productivity.
Easy Machine Control The R 984 C’s hydraulic control system is optimized
in order to improve combined machine motions. The
confi guration and placement of operator control
elements and monitoring displays are perfectly
coordinated to support the productive performance.
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 984 C’s attachment ensures
the highest forces, easy bucket penetration and
high fi ll factor to perform even in the most demand-
ing conditions.
Power-Oriented
Energy Management The R 984 C’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.
