R 936 Litronic
Performances
Modular quick-change system
made by Liebherr
• Likux – connects all hydraulically
mounted tools without having to leave
the operator’s cab, maximum produc-
tivity due to tool change being
performed in a matter of seconds
• The suitable digging tool for every
application. Your machine is a multi-
functional tool carrier and will pay
for itself very quickly indeed
• Mechanic and hydraulic Liebherr
quick-change adapter
Thanks to its innovative excavator system technology, the R 936 crawler exca-
vator has performance features that are truly unique. Characteristic elements
of this system technology include the particularly effective and energy-efficient
Positive Control twin-circuit hydraulic system, which was specifically designed for
machines with a high level of superimposed functions and operational movements.
The electronic pump control arrangement sets this technology apart, creating
a new standard for performance and quantity control that entirely matches the
operator’s needs.
Integrated excavator system technology
High-tech for high
performance
Among the high-tech equipment on the Advanced
version of the R 936 is the newly-developed inte-
grated excavator system technology. This is based on
the Positive Control hydraulic system, controlled by
Liebherr electronics and the system software. The
sensors located at strategic points on the machine
form the basis for an intelligent system that allows for
fast and uent working.
Positive Control
twin-circuit hydraulic
system
When travelling straight or in a curve, and during
levelling work, the two pump circuits of the hydrau-
lic system are separated or grouped together, as the
need arises. Separation of the systems means that
different consuming components can be supplied
with different load pressures independently, and
saving energy too. By contrast, grouping the pump
circuits allows for maximum speeds with individual
or superimposed movements, and that means opti-
mum energy utilisation.
Power and speed
Faster work cycles
The R 936 achieves particularly fast work cycles,
thanks, for example, to the powerful slewing drive of
the superstructure, the rapid slewing rates, and the
creation of high slewing torque.
Operating
pressure
With an operating pressure of 380 bar, the R 936
achieves higher hydraulically limited load capaci-
ties and higher digging forces, of up to 152 kN,
and break-out forces of up to 193 kN; perfect for
more difficult operational situations such as canal
or pipeline construction.
