Liebherr R 9800 - Manual (Page 7)

7 R 9800
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
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 hy-
draulic system and the optimized pipe and hose
layout maximize usable power transmission. The hy-
draulic pumps are electronically managed to provide op-
timal 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 con-
siderably extend the time between service intervals.
Comfortable Cab for Effi cient Work
Superior Operator
Comfort 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.
Working Environment
Total Control The R 9800’s cab offers a panoramic view over
the entire attachment and loading spot. Two out-
side cameras show areas that cannot be observed
directly. Long-distance xenon working lights promote
effi cient loading.
