Performance
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 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 under-
carriage.
Reliability
Backed by more than 30 years experience in the con-
struction 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.
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 Mate-
rial 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 elec-
tric 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 in-
spection points, so as to minimize down time.
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 op-
erating charges, and reducing profi t margins consider-
ably. Environmental criteria, in particular CO
2
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 con-
ventional 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).
