Performance
These new electric Material Handlers have been designed to meet the specifi c
needs of industrial handling. A wide range of equipment and uppercarriages opti-
mized for long working radius provide the ideal answer to all the demands which
arise in the industry. The performance of the kinematic chain formed from com-
ponents from our in-house production, combined with the power of the electric
motor, maximize the performance of the machine when it comes to lifting power,
precision, and speed of operation. The equipment’s performance is enhanced by
the mobility provided by the crawler undercarriage.
Exceptional lift capacity Thanks to optimized kinematics and uppercarriage,
the machines offer extended reach and balance
with a better absorption of mechanical forces.
Excellent Working
Radius
Designed for the most demanding applications, the
machines offer extended reach and lift capacity in
wide working radius.
Fast work cycles The ER 934 C, ER 944 C and ER 954 C electric
excavators are fitted with the Liebherr Torque Con-
trol system. The hydraulic guidance system on the
excavator operates as a closed circuit, and does
not affect the speed of movement of the equip-
ment during the working cycle. The high torque and
high oil delivery from the guide pump maximize the
excavator swing speed.
A two-pump hydraulic system allows for operating
speeds to be reached which are unequalled any-
where. Regeneration on the circuits for the equip-
ment allows for optimization of the hydraulic power
available and minimizing response time to the opera-
tor’s commands.
Precision The hydraulic control allows for exceptional preci-
sion - even at extended reach - contributing to the
confidence of the operator and achieving high perfor-
mance as a result.
