Efﬁ ciency

The R 9400 follows the Liebherr design philosophy of maximizing the machines

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.
