power-to-weight ratio stands for maximum productivity in all operating conditions. Whether ripping hard
ground, moving material or grading surfaces, the outstanding performance of the PR 754 and PR 764 never
fails to impress.
Reliability
Sturdy and strong: Liebherr crawler tractors and the
materials used to build them are designed for long,
trouble-free life. Components subject to severe loads
are made from high-strength materials, and points
exposed to possible damage are well protected.
Liebherr crawler tractors owe their high levels of availability to these stringent reliability standards.

Performance
Liebherr has successfully been building crawler tractors with hydrostatic transmission for the past thirty years. The generation 4 models exemplify power, efficiency
and capability in a wide range of applications.
Outstanding productivity
Impressive power
and drawbar pull
High traction and
ripping power
Bogie suspension
Outstanding
maneuverability
Optimized blade
patterns
Low center of gravity
The powerful Liebherr diesel engine, combined with
Liebherr’s innovative driveline, makes ample power
available for every working situation. The hydrostatic
drive requires no gear shifting: engine power reaches
the tracks without interruption, even when turning.
Thanks to the hydrostatic transmission, the operator
simply selects the most suitable working speed. The
system automatically maintains peak engine rpm and
power efficiency. Track slip is kept low and maximum
power is continuously transferred to the tracks.
For work on uneven or rough surfaces, Liebherr offers
different types of bogie undercarriages for increased
traction and pushing power.
The hydrostatic drive is particularly suitable for ripping
work. The machine can be turned quickly, the rear
mounted ripper positioned accurately between hard
rock layers, and the material broken out with the necessary force.
The blades for the PR 754 and PR 764 have had their
penetration and rolling behavior optimized, to increase
their transport capacity.
The driveline assemblies are compact so that the complete machine has a very low center of gravity, thereby
allowing safe operation on steep slopes.
Liebherr hydrostatic transmission
• Automatic speed and torque adjustment
keeps the engine working at optimal
power as the load changes.
• Even at low speeds, for example in
demanding ripping operations, the thermal load of the hydrostatic travel drive
remains low. The efficiency of the drive
remained virtually unchanged.
Generous ground
clearance
The well-planned component layout is designed for
maximum ground clearance. Heavy duty belly pans
prevent damage when working on rough stone or rock.
Oscillating roller tracks
• When working on uneven surfaces,
oscillating bogie undercarriages
increase the ground contact area
and improve traction. In addition, the
resilient mountings effectively absorb
shock loads.
• For work on softer, more yielding
surfaces such as coal or wood chips,
tracks with rigid rollers are used.

Constant engine speed
keeps fuel consumption low
• Since the engine’s nominal operating speed is in the region of its lowest
specific fuel consumption, maximum
operating economy is assured.

Economy
Liebherr crawler tractors are designed with economy in mind, featuring low fuel
consumption, high productivity, extended component life and minimum maintenance costs.
Low fuel consumption
Constant low
engine speeds
The Liebherr diesel engine always operates at a constant speed – in the most economical rpm range –
regardless of the actual travel speed.
A low mean piston speed boosts cylinder filling and leads
to more efficient combustion of the fuel-air mixture.
Efficient driveline
Hydrostatic transmission delivers the best possible
level of efficiency over the full speed range. Even
when peak power at low ground speed is required e.g. when ripping - the oil temperature remains low.
Load-sensing
implement hydraulics
This system keeps energy consumption down to the
level needed by the hydraulics at any given moment. It
saves fuel when the work tools are not being operated.
Low maintenance costs
Good accessibility
Longer maintenance
intervals
All the diesel engine’s servicing points are grouped
together centrally, and can be easily reached. The hydraulic tilt cab makes it even easier to reach the various
mechanical assemblies for quick, effective servicing.
Maintenance intervals are optimally matched to the
various components and assemblies. Where parts are
exposed to dirt and dust, for instance on the pushing
frame, maintenance-free bearings are used.
Tiltable cab
• For easy, quick access to all drivetrain
and hydraulic components.
Simple maintenance
• All the servicing points are located
centrally and are easy to reach,
minimizing the time spent on daily
inspection work.
Long-life tracks
Large track
components
High-quality components with ample dimensions prolong the operating life of the undercarriage.
Liebherr Litronic control system
• Liebherr’s Litronic control system matches
travel speed ideally to the task at hand.
• Track slip is kept to a minimum in pushing as
well as in ripping applications; this improves
power transmission and prolongs track life.

The ideal configuration for every task
• For mining or applications in abrasive
materials, optional wear plates increase
machine operating life.
• Liebherr offers special machine configurations for landfill, coal, or woodchip
applications, as well as for low ambient
temperatures.

Reliability
Well-proven technologies and high quality are what keeps a machine ready for use.
Liebherr develops and builds its own components and assemblies specifically for
use on construction and civil engineering machinery, so that their strength can be
guaranteed however difficult the application.
Liebherr powertrain
Liebherr engines
Liebherr diesel engines have been developed for the
toughest imaginable operating conditions. A rigid ladder-type frame reduces engine vibration and provides
the strength needed for maximum operating reliability
and long service life.
Wear-free driveline
concept
A tried and tested system: Liebherr’s hydrostatic travel
drive needs no torque converter, manual-shift gearbox,
differential steering or steering clutches. The system’s
hydraulic pumps and motors are standardized, effectively wear-free in operation and exceptionally reliable.
Long-life final drives
Of ample dimensions, Generation 4 final drives are
designed to withstand the most severe loads. Double
transmission seals with automatic leak detection enhance reliability even more.
Robust steel construction
Box-section main frame
Rear-mounted ripper
The main frame is of box-section design – a wellproven principle for maximum torsional stiffness and
optimal absorption of forces. Cast steel is used for
components subject to high stress.
Liebherr rippers are built for heavy-duty tasks, and
have extra protection at all areas exposed to wear.
Component endurance tests
• Even at the design stage, components
are subjected to FE analysis in order to
determine their dimensions in relation to
the loads they will encounter.
• All components undergo long-term laboratory and field testing, and only those
that comply with Liebherr’s high quality
standards are approved for production.
Secrets of long-term reliability
Modern cooling system
Protected electrics
Two hydrostatically driven fans and a wide-meshed radiator guarantee optimal cooling performance, even in
dusty environments.
High quality cable protection prevents mechanical
damage to the cable harness.
Modern cooling system
•
Two electronically controlled fans draw in the volume
of air actually needed to keep the hydraulic fluid and
engine oil temperatures stable as loads vary. All components operate in their most favorable temperature
ranges, thus avoiding unnecessary strain and prolonging their trouble-free operating life.
• Cooling air is drawn in from clean zones around
the machine, to keep dust contamination to a
minimum.
• Optional: a reversible fan for automatic radiator
cleaning when operating in extremely dirty or
dusty conditions.

Comfort
The operator’s work area has been redesigned for an exceptionally high level of
comfort and convenience. There is ample space, the controls are laid out ergonomically and the noise level is low. Liebherr cabs provide perfect conditions for
concentrated work without fatigue. The excellent view makes safe, accurate operation much easier.
Outstanding cab design
Ergonomics
The well-planned cab layout makes conditions ideal
for stress-free, efficient operation of the machine. All
instruments and controls are clearly laid out and within
easy reach.
Low noise levels
Thanks to effective sound insulation and the use of
modern, quiet-running diesel engines, the PR 754 and
PR 764 feature exemplary noise levels that are well
below the legal limits.
Outstanding view
Integral ROPS/FOPS protection large window area
provide the operator with the best possible view in
every direction.
Simple, precise control
Single joystick control
Stepless speed control
Safety in every situation
A single joystick controls all travel movements conveniently and accurately, including the ’counter rotation’ function.
Ground speed can be selected without gear changes
and therefore with no interruption to the transmission
of power.
Even on steep gradients, the crawler tractor is always
positively driven. Since the system cannot freewheel
(hydrostatic transmission), the operator controls braking simply by moving back the travel joystick. When
the machine comes to a halt, the parking brake is applied automatically for additional safety.
Well-planned details
• A large storage compartment is standard, and includes a 12 Volt power.
• The seat with its wide range of
adjustments and three-position
armrests helps to provide a
pleasant work area for the operator.
• Many other details, for example
a sliding side window, tinted
glass and a footrest, add to the
operator’s comfort.
