Comfort
In the cab the driver can look forward to a workplace
designed in accordance with the very latest findings in
ergonomic science, with emphasis on comfort and ease
of operation. The optimised arrangement of the hydraulic
hoses means that the driver has en even wider field of
vision, and the heating and climate control system fitted
as standard means pleasant working conditions inside,
whatever the weather. Liebherr crawler excavators are
also particularly easy to service – maintenance tasks can
be carried out easily and rapidly at readily accessible
service points.
Performance
Thanks to its innovative Advanced excavator system
technology, the R 936 crawler excavator has performance
features that are truly unique. Characteristic elements of
this system technology include the particularly effective
and energy-efficient Positive Control twincircuit 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.
Reliability
Liebherr provides customers with solutions that lead the
way for the future, solutions for maximum equipment
reliability and availability, solutions which satisfy the
most extreme demands for performance and quality.
With more than 50 years experience in the construction
of hydraulic excavators, we have an advantage in design
and consultation that clearly sets us apart.
Economy
Crawler excavators from Liebherr guarantee maximum
productivity. The optimum interplay of hydraulics and
electronics means that individual movements and superimposed movements alike can be carried out particularly
efficiently. And, perhaps last but by no means least, the
perfect harmonisation of all the components means that
energy expenditure during operation can be kept to an
absolute minimum.

Safe work – with a clear layout
A pleasant workplace
High-resolution
colour display
Wide camera field

Fully automatic
climate control system
Minimal noise
and vibration
The entirely new design of the cab provides plenty
of room, and creates a pleasant sense of space.
Cab windows in the front, the roof, and on the right
are made of break-resistant two-pane safety glass.
The front windscreen is a two-part design and can
be completely retracted. The cab meets ROPS requirements, providing the driver with even more
protection.
The 7-inch high-resolution colour display can be
operated as a touch-screen system. Thanks to its
high resolution, the video-style display reproduces
the image from the rear area monitoring camera
in the best possible quality. It comes with versatile
adjustment, control, and monitoring capabilities, and
is designed to be glare-free.
The reversing camera for the R 936, fitted as standard, provides a wide-ranging view of the area behind the machine.
The climate control system has more than 12 ad-
justable nozzles for individual control of air ow, and
can be operated via the display.
The new cab on the Liebherr crawler excavator meets
the standards for noise emissions and whole-body
vibrations, which makes work a pleasure.

High stability undercarriage
Better force distribution
The undercarriage concept leads to increased performance with improved service life. Thanks to the
connection of the middle section being extended as
far as the ends of the chassis beams, known as the
X-design, the forces are better distributed, which
increases the service life of the undercarriage.
Technology with perspective
Quality right down
to the last detail
Perfect optimisation
The at-a-glance layout of the hydraulic, lubrication,
and electricity lines makes for optimum functional
reliability and maximum availability of the unit. Best
possible corrosion protection is guaranteed thanks
to components and modules being finalpainted and
surface treated before assembly.
Individual components of the drive train, manufactured in-house, such as diesel engine, traction drive,
rotary actuators, operating pump and hydraulic
cylinder are perfectly optimised with one another.
As components of a total system designed for long
operational life, they guarantee maximum possible
reliability.
Safety of functionality
Safety of functionality
ROPS cab structure
The cab is equipped with an integrated roll-over
protection system (ROPS) in accordance with
ISO 12117-2, guaranteeing driver safety in any
situation.
LiDAT data transfer system
• Complete eet management,
all from one source
• Optimized economical performance of
the machine park thanks to detailed
view of the distribution of operating
states and times
• Reports on capacity commitment and
the use of the machine park can be
called up daily via the Web portal
• Precise location of the machine
• Regional delimitation and xed down-
times increase safety and reliability
Automatic control
of functionality
The operator can entirely focus on his job, because the integrated on-board electronic continuously performs a comparison with pre-determined
target data. Eventual deviations from the target
parameters are shown on the display.
