Performance
These new electric Material Handlers have been designed
to meet the specific needs of industrial handling. A range
of equipment even wider for the High Rise and uppercar-
riages 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 as well as the height of work adapted to the in-
dustrial process.
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 High Rise with the
aim of providing top performance whatever the challenge
might be. The structure of the machine, using compo-
nents 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 com-
ponents has also been increased, thanks to the
constant regime of the electric drive. The concept of the
single actuator (one single electric motor for all the hy-
draulic 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 com-
fortable driving position, good panoramic visibility, and a
highly ergonomic layout of the controls. The new electric
Material Handlers offer the same level of comfort as on the
thermal 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 inspec-
tion points, so as to minimize down time.
Economy
Investing in the acquisition of an electric Material Han-
dler 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 con-
siderably. Environmental criteria, in particular CO
2
emis-
sions, 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). Mobility is added to
economy, through custom cable reels solutions.
