5 R 9350
Productivity
High Altitude Kit (Option)
Designed to offer maximum effi ciency
and productivity for operation in
high altitude:
• Solution integrated in machine
structure
• Adapted engine
• Pressurized hydraulic tank
• Available with the Arctic Kit
Liebherr Ground Engaging Tools (GET)
Liebherr has developed a complete mining
GET solution to complement Liebherr’s min-
ing backhoe and face shovel bucket design.
A synergy that enables easy material pen-
etration 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 R 9350 is built to outperform all competitors in the medium class mining market.
Boasting a 18,00 m³ / 23.5 yd³ bucket capacity in standard confi guration, the R 9350
is the ideal machine to load a fl eet of 100 t dump trucks. Available in both diesel or
electric versions, the R 9350 offers the fl exibility to perform many specifi c applications.
Engineered for Intense Mining
Powerful Drive System The R 9350 is equipped with a Cummins diesel
engine which has been specifi cally adapted to with-
stand the most extreme environments and to reach
the highest uptime performance for maximum pro-
ductivity. The electric drive system provides superior
performance when the machine is used in the most
specifi c conditions.
Optimized Cycle Times Rather than using open hydraulic circuit, the R 9350
employs a closed-loop swing circuit to enable maxi-
mum swing torque while retaining the full oil fl ow for the
working circuit. The independent swing circuit in com-
bination with the powerful drive system leads to fast
arm motion, which contributes to faster cycle times.
Precise Machine
Motions The R 9350 design integrates the Litronic Plus electronic
control system to allow for easy control even when
simultaneous movements are required. The patented
Liebherr electronic damping system provides controlled
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 dig-
ging and lifting forces. Integrating Liebherr-made cyl-
inders and a wide range of buckets with mining-opti-
mized GET, the R 9350’s attachment ensures the high-
est forces, easy bucket penetration and high fi ll factor
to perform even in the most demanding conditions.
Power-Oriented
Energy Management The R 9350’s attachment is equipped with the pres-
sureless boom down function to enable fast cylinder
retraction without the need for pump energy. Intel-
ligent energy management diverts the pump fl ow
during boom lowering, allowing other cylinder
motions to operate unimpeded.
