These new electric Material Handlers have been designed
to meet the specific needs of industrial handling. A wide
range of equipment and uppercarriages optimized 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 components 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.
Comfort
Helping the operator to concentrate on his work and get
the best out of his machine is achieved by providing a
comfortable driving position, good visibility, and a highly
ergonomic layout of the controls. The new electric Material Handlers offer the same level of comfort as on the
mobile excavators (arrangement of the controls, driver’s
seat, climate control, large window areas, etc.). The electric motor system adds a further layer of comfort thanks
to the low noise emissions and absence of vibration. For
Liebherr, comfort also means ease of daily maintenance
of the machine in terms of access to the service and inspection points, so as to minimize down time.
Reliability
Backed by more than 30 years experience in the construction of electric excavators, Liebherr designed the
new ER 934 C, ER 944 C and ER 954 C with the aim of
providing top performance whatever the challenge might
be. The structure of the machine, using components from
our own manufacture for the electric drive, has been
completely rethought, and so moves away from simply
being an adaptation of a diesel-engine machine. Being
intended for key functions in the organization of industrial
sites, Liebherr electric Material Handlers provide a very
high level of reliability. The service life of the hydraulic
components has also been increased, thanks to
the smoother movement of the electric drive. The
concept of the single actuator (one single elec-
tric motor for all the hydraulic functions) allows
all the low-voltage functions to be concentrated
in a single box.
Economy
Investing in the acquisition of an electric Material Handler
is a great long-term advantage. Constant increases in the
costs of conventional energy sources are pushing up operating charges, and reducing profi t margins considerably. Environmental criteria, in particular CO2 emissions,
are also playing a constantly greater part in the choice of
power systems and working methods. With the electric
drive, Liebherr offers an economical alternative to conventional diesel-engine machines, and a solution with
real respect for the environment. Also, the excavator is
permanently available, with no need to refill. There are no
constraints (e.g. DPF or AdBlue).

Exceptional lift capacity
Excellent Working
Radius
Fast work cycles
Precision
Thanks to optimized kinematics and uppercarriage,
the machines offer extended reach and balance
with a better absorption of mechanical forces.
Designed for the most demanding applications, the
machines offer extended reach and lift capacity in
wide working radius.
The ER 934 C, ER 944 C and ER 954 C electric
excavators are fitted with the Liebherr Torque Control system. The hydraulic guidance system on the
excavator operates as a closed circuit, and does
not affect the speed of movement of the equipment 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 anywhere. Regeneration on the circuits for the equipment allows for optimization of the hydraulic power
available and minimizing response time to the operator’s commands.
The hydraulic control allows for exceptional precision - even at extended reach - contributing to the
confidence of the operator and achieving high performance as a result.

Electrical
system
Protected
electric cabinet
Electric motor
Totally integrated into the structure of the uppercarriages
and accommodated in a metal container, the electric cabinet
provides a three-fold level of protection to the components
of the electrical system:
- Mechanical (insulation from vibrations and from the possible impact of falling objects)
- Heat (maintains a constant temperature thanks to the heating resistors which prevent corrosion from condensation)
- Electrical earthing of the structure and disconnection from
current is controlled from the cab by way of a motorised
circuit-breaker.
The electric cabinet, such as the collecting pipe, provides
IP55 class protection. A filtered ventilation system which
avoids any dust penetration and, with permanent ventilation, ensures the thermal balance of all the components.
Liebherr electric excavators are equipped with motors especially designed for really tough applications. The dimensions
of the motor allow for the full power to be drawn from the
kinematic chain, and so maximises the performance of the
machine especially in the combined movements. The motor
can resist a momentary overload of up to +25 % of its rated
capacities. Protected against penetration by water and dust,
its properties correspond to protection class IP55.
The temperature of the roller bearings and other bearing
elements is constantly monitored, and, in the event of overheating, the operator is warned of malfunction on the console at the driving position.

Liebherr electric excavators are really quiet in operation. Their measured acoustic level is from 4 to
5 dB lower than an equivalent diesel-engine version.
The level of noise intensity from a Liebherr electric
excavator represents less than a third of the noise
generated by a diesel-engine unit.

Flexibility and versatility
Energy costs cut
Increased service life
Maximum availability
Liebherr electric Material Handlers are multi-tasking
machines. With a wide range of tools, which can be
combined with Liebherr quick-coupling systems,
they can create a degree of flexibility and versatility
which has no comparison anywhere.
The energy yield from an electric motor is greater
than that of a diesel-engine. Delivering the same kW
output in hydraulic power costs three to five times
less with an electric excavator than with a diesel-engine unit. Liebherr excavators deliver the full power
from their kinematic chain and at a lot less cost.
The smooth actuation of the electric drive and the
reliability of Liebherr hydraulic components mean
that the maintenance costs of the excavator can be
reduced considerably.
The absence of vibrations and variations in output
from a motor, which operates on a torque principle
and at constant output, means that the stress on
the kinematic chain can be reduced and the optional pre-heating of the hydraulic system allows for the
hydraulic oil to be kept at an optimum temperature
right from the start.
The costs associated with maintenance operations
are reduced to a minimum, and that also cuts downtimes. The electric motor does not require any maintenance beyond lubrication of the bearings every
3,000 hours. No filters (air, oil) to be changed and no
draining of engine oil throughout the entire service
life of the machine.
