Liebherr R 956 - Manual (Page 5)

5 R 956 Litronic
Performances
Floating Boom Function
• Increased hydraulic flow for the
other cylinders (stick and/or bucket
for example)
• More power available, making it easier
to extract materials and reduce work
cycle times
• Increased service life when a hydraulic
hammer is used
Choice of work mode
The different work modes offered allow you to adapt the power
of the excavator to the application
E Mode - Economy: for economical and ecologically-friendly
operation. Minor restriction of power without affecting the load
lifting and excavating capacities. Highly recommended for light
and moderate working conditions
P Mode - Power: for high excavation capacities and difficult
applications. Pump flow and power are not limited
S Mode - Sensitivity: for precision jobs and loading of materials.
The pump flow and power are restricted to attain optimal sensitivity
P+ Mode - Full Power: especially designed for increased power;
only recommended for extreme applications
Responsive and precise, the R 956 crawler excavators allow you to perform a
large number of mass excavation tasks in earthmoving sites or in quarries. Thanks
to their tested hydraulic design and their various work modes, Liebherr excava-
tors will always be there to satisfy your needs.
Technology serving productivity
Liebherr Integration All the major components are designed and man-
ufactured within the Liebherr group. This includes
components such as the heat engine, hydraulic
pumps, electronic components (injection mapping,
hydraulic control, control console) and of course the
essential mechanical elements including cylinders,
the slewing ring and work tools, resulting in an over-
all increase in productivity.
Regeneration Plus The „Regeneration Plus“ function allows for the
accelerated lowering of the boom, reduced losses
of pressure and an improved work cycle. The opti-
mization and combination of the „zero-pressure
lowering of the boom“ and „Regeneration plus“
functions, together with the increased power of
the hydraulics, provide increased performance and
lower consumption.
Power and speed
Increased
break-out force
Thanks to their kinematics and hydraulic power, the
R 956 crawler excavators develop increased break-
out and digging forces. The generously sized cyl-
inders allow you to increase the break-out perfor-
mance in hard materials.
Faster cycles The mechanical link between the rotation engine
and slewing ring gives the machine a high torque
and swing speed, thus improving your operating
cycles.
