Effi ciency
The R 9400 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 9400’s spacious 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 9400’s energy optimization. The high-pressure hy-
draulic 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 the
engine circuit 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 9400’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 9400 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 9400’s cab offers a panoramic view over the
entire attachment and loading spot. Two outside
cameras show areas that cannot be observed
directly. Long-distance halogen working lights
promote effi cient loading.
