Productivity
High Performance Option
The optimised design increases the
overall production rate without com-
promising the component life. This
remarkable feat is achieved by:
• Decreasing the weight
• Converting attachment weight
into payload or bucket protection
• Maintaining the original
attachment design life
Litronic Plus – Electronic Control
A power management system developed
to optimize electrical, mechanical, hydraulic
power distribution which encompasses:
• Liebherr designed and built power
components
• Continuous monitoring of the engine,
electrical and hydraulic systems
• Safe, fast and precise control
• Optimum equipment operation
• Productivity and effi ciency maximization
The R 9800 is built to outperform all competitors in the Ultra class mining market.
As a perfect loader for 200 t, 290 t and 360 t class dump trucks, the R 9800 is the
right match for the Liebherr T 284. Developed as the optimal loading tool for large
scale mining operations, the R 9800 can achieve the most challenging targets.
Engineered for Intense Mining
Powerful Drive System The R 9800 can be optioned with two versions of
diesel drive systems. Customers can choose between
Cummins or MTU as their preferred engine partner. An
optional electric drive system provides outstanding
performance when the machine is used in the most
specifi c conditions. The R 9800 combines fl exibility
and productivity to meet customer expectations.
Fast Cycle Times Rather than using open hydraulic circuit, the R 9800
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.
Precise Machine
Motions The R 9800 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, the R 9800’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 9800’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.
