5 PR 724 Litronic
Performance
Liebherr has been successfully building hydrostatically driven crawler machines for
more than 30 years. The powerful latest-generation PR 724 is the ideal machine
for many different applications.
Excellent grading characteristics
Long running gear The long, geometrically optimized undercarriage en-
sures smooth, extremely low-vibration travel charac-
teristics.
High-strength main
frame construction
The main frame and oscillating bar are particularly re-
sistant to buckling. The oscillating bar with its elastic
bearing absorbs vibrations to allow optimum grading.
High pushing power
Powerful engine The characteristics of the diesel engine are tuned to
the high power required when pushing material and
cornering. This provides smooth, powerful power in all
situations.
Drive train for
maximum traction
The hydrostatic travel drive requires no gearshifting,
the engine power is transmitted to the tracks without
interruption – even while steering. This means the op-
erator can comfortably control the travel speed.
Versatile in use
Excellent
maneuverability
Another strength of the hydrostatic travel drive be-
comes apparent when operating in confined spaces.
All steering movements can be performed quickly and
powerfully – right up to true counter rotation.
Low center of
gravity and high
ground clearance
The intelligent arrangement of the drive components
allows quick and safe work, even on slopes and banks.
The PR 724 has sufficient ground clearance to operate
on the heaviest soil and roughest terrain.
A wide range
of equipment
Many different blade types, rear attachments and un-
dercarriage configurations variations are available,
which means the PR 724 can be ideally configured for
multiple applications.
Grading characteristics
• The ideally positioned blade and the
inside-mounted pushing frame give
the operator an excellent view of the
corners of the blade and the ground
underneath.
• The perfectly coordinated front
equipment, working hydraulics and
the machine itself ensure unsur-
passed grading performance and
a perfect cut every time.
Liebherr hydrostat
• The hydrostatic drive offers unin-
terrupted power transmission and
therefore maximum power and
safety in every operating situation.
• Power limiting control with auto-
matic speed and torque adjust-
ment ensures maximum efficiency
at every speed.
