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 R 9400 is built to outperform all competitors in the medium class mining market.
Boasting a 22,00 m³ / 28.8 yd³ bucket capacity in standard confi guration, the R 9400
is the ideal machine to load a fl eet of 135 t dump trucks. Available in both diesel or
electric versions, the R 9400 offers the fl exibility to perform many specifi c applications.
Engineered for Intense Mining
Powerful Drive System The R 9400 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. 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 9400
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
combination with the powerful drive system leads to
fast arm motion, which contributes to faster cycle times.
Precise Machine
Motions The R 9400 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 digging
and lifting forces. Integrating Liebherr-made cylinders
and a wide range of buckets with mining-optimized
GET, the R 9400’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 9400’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.
