Performance
These new electric Material Handlers have been designed
to meet the specific needs of industrial handling. The
considerable advantage of the semi-stationary machine
is its mobility; a result of the crawler undercarriage. The
material-handling machine can be ideally placed in the
application area’s existing infrastructure without the
necessity for any alterations or rebuilding measures.
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.
Reliability
Backed by more than 30 years experience in the con-
struction of electric excavators, Liebherr designed the
new ER 934 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 pro-
vide 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 electric
motor for all the hydraulic functions) allows for the risk
area associated with the low voltage at the electric cabi-
net to be reduced even further.
Comfort
Helping the operator to concentrate on his work and
get the best out of his machine is achieved by provid-
ing 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 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 mainte-
nance of the machine in terms of access to the service
and inspection points, so as to minimize downtime.
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 profit 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.
