Effi ciency
The R 9250 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 9250’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 9250’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 9250’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 The large and spacious cab which equips the
R 9250 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 9250’s cab offers a panoramic view over
the entire machine and loading spot. Two outside
cameras show areas that cannot be observed
directly. Long-distance halogen working lights
promote effi cient loading.
