Modular quick-change system

made by Liebherr

• Likufix – connects all hydraulically

mounted tools without having to leave

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

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 fluent 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.
