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.
