Modern drive concept
• Powerful, 6-cylinder Liebherr turbo-charged Diesel engine
type D846 A7, 370 kW/503 h.p, exhaust gas emissions
correspond to the directives 97/68/EG stage 3 and EPA/CARB
Tier 3, robust and reliable, modern, electronically controlled
engine management
• ZF power shift gear with automated control system ASTRONIC. ZF intarder fitted directly to the gear unit, 12 forward
and 2 reverse gears, automated control, reduced fuel
consumption due to a great number of gears
• 2-step, robust transfer case with lockable transfer differential,
creeping speed 0.78 km/h
• Drive 10 x 6, axles 2, 4 and 5 driven
• Drive 10 x 8 (optional), axles 2, 4 and 5 driven,
axle 1 activatable for off-road displacement
• Weight-optimized, robust axles of minor maintenance, perfect
track keeping and lateral stability due to special arrangement
of the steering knuckles, steel- and rubber mounted
• Maintenance-free cardan shafts; easy and quick fitting due
to 70° diagonal toothing
• Hydropneumatic suspension "Niveaumatik",
program-controlled for "setting crane on outriggers",
"crane displacement with equipment" and for
"road displacement of the crane",
suspension travel +150/-150 mm
• Lateral force released and maintenance-free suspension
rams, protected against damage by synthetic pipes
• Sustained-action brakes:
Engine brake as exhaust retarder with Liebherr additional
brake system (ZBS), Intarder on gear, Telma-type eddy
current brake (optional)
• Service brake:
All axles fitted with air disc brakes, high braking performance,
long maintenance intervals, rapid-change brake linings

Variable steering concept with
"active rear-axle steering"
Axles 3, 4 and 5 set up as "active rear-axle steering, 5 steering
methods are preselectable by fixed programs (P):
P1 On-road steering
Axles 1 and 2 are steered mechanically with hydraulic assistance
by the steering wheel. Axles 3, 4 and 5 are steered “actively”
speed-dependent according to the cramp of the front axles,
and over 30 km/h, axles 3 and 4 are set to straight displacement
and fixed, from 60 km/h, axle 5 is fixed equally to straight
displacement. The change of the steering angle in accordance
with the speed, results in a precise and stable driving quality
during higher speeds, tyre abrasion is reduced and the
maneuverability clearly improved.
P2 All-wheel steering
Axles 3, 4 and 5, dependent on the steering angle of axle 1
are cramped by means of the steering wheel so that the
smallest turning radii can be performed.
P3 Crab steering
Axles 3, 4 and 5 are cramped into the same direction as axles
1 and 2 by means of the steering wheel.
P4 Steering without swerving
Axles 3, 4 and 5 are cramped in accordance with axle 1 so
that no swerve out of the rear of the carrier takes place.
P5 Independent rear-axle steering
Axles 1 and 2 are cramped by the steering wheel, axles 3, 4
and 5 steered independent of the cramp of axles 1 and 2 by
momentary-contact buttons, whereby the cramp of axle 3 is
adapted to the required situation.
• A failure in the rear-axle steering does make it ineffective
and the rear axles are set to straight displacement by the
centering rams
• Two independent hydraulic circuits with wheel- and engine
driven hydraulic pump, thus maximum safety standard
• Two independent control processors (by existing E/A modules)
and diversified sensoriel system
• Entire know-how of the "active rear-axle steering" by Liebherr
