Productivity
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
Power-Oriented
Energy Management
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.
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.
High Performance Option
The optimised design increases the
overall production rate without compromising 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

Machine Monitoring System
Integration of the Liebherr-made monitoring
system:
• 10.5’’ LCD color 8-key screen
• Information interface to operator
• On-board diagnostics to service staff
• Real text information
• Long term data storage for maintenance

Effi ciency
The R 9800 follows the Liebherr design philosophy of maximizing the machines
performance by improving the effi ciency of all individual subsystems. Engineered
for optimum serviceability, the machine is designed to ensure maximum uptime.
The R 9800’s modern cab creates a comfortable working environment ensuring
peak operator performance, every shift.
Optimized for Maximum Profi tability
Electro-Hydraulic
System Effi ciency
Liebherr hydraulic technology in combination with the
precision of electronic control contributes to the
R 9800’s energy optimization. The high-pressure hydraulic system and the optimized pipe and hose
layout maximize usable power transmission. The hydraulic pumps are electronically managed to provide optimal pressure compensation and oil fl ow management.
The hydraulic system is independently regulated over
both engine circuits for the best operational effi ciency.
Cooling System
Effi ciency
The oversized independent oil- and water coolers
in combination with low energy consumption fans
and on-demand cooling controls enable to maximize
available power for digging process.
Optimized Service
Intervals
The R 9800’s high pressure hydraulic oil fi ltration
systems remove contaminants from the fl uid to offer
the highest rate of hydraulic system effi ciency. To
maintain the oil quality, all return hydraulic oil fl ow goes
through a 15/5 μm fi ne fi ltration system. To promote
availability, the grease and fuel tanks are sized to considerably extend the time between service intervals.
Comfortable Cab for Effi cient Work
Superior Operator
Comfort
Working Environment
Total Control
The large and spacious cab which equips the
R 9800 offers ideal working conditions and optimal
operator’s comfort. Mounted on silent blocks, the
cab design reduces vibrations and limit noise
pollution to provide a quiet environment.
The R 9800’s cab offers a panoramic view over
the entire attachment and loading spot. Two outside cameras show areas that cannot be obser ved
directly. Long-distance xenon working lights promote
effi cient loading.
Fast Maintenance System
The service fl ap is hydraulically
actuated and accessible from
the ground level allowing for fast
maintenance:
• Hydraulic oil refi ll
• Engine oil refi ll and drainage
• Splitter box and swing gearbox
oil exchange
• Attachment/swing ring bearing
grease barrel refi lling with fi lters
• Windshield washer water refi lling
• Fast fuel refi lling line
Hydraulic System Effi ciency
• Optimal oil fl ow distribution through the valves
blocks reducing hydraulic losses
• Reduced pressure drops between pumps and
consumers (hydraulic motors / cylinders)
• Allows the combination of the main movements
under maximal forces
• Earlier maximal forces generation for an
accurate control of the combination of force
and cylinder speed
• Increased hydraulic oil cooling effi ciency
• Enables fast cycle times
