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 op-
timized for a long operating 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 own
in-house production, combined with the power of the electric motor, maximize
the performance of the Material handlers when it comes to lifting power, preci-
sion, and speed of operation.
Great lifting power Thanks to the optimised rear offset and the broach
kinematics of the equipment, the design concept
of the new uppercarriages means they can oper-
ate at exceptional outreach whilst guaranteeing a
good balance of forces and better absorption of
mechanical stresses.
Excellent Working
Radius Tough and designed for the most demanding of
applications, Liebherr equipment systems are
the perfect answer to every requirement when
it comes to lifting power and range of outreach.
Components are optimised by the fi nite element
calculation method.
Fast work cycles The EP 934 C, EP 944 C and EP 954 C electric ex-
cavators are fi tted with the Liebherr Torque Control
system. The hydraulic guidance system on the ex-
cavator 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 ex-
cavator rotation 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 op-
erator’s commands. This all results in a fl uidity of
movements which operators really appreciate.
Precision of work The fi ne response of the hydraulic control allows
for exceptional precision of work to be achieved
at long outreach, which contributes to the comfort
and convenience of the operator as well as achiev-
ing high performance results. Power is nothing
without control.
