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
Variable steering concept with
"active rear-axle steering"
• Standard application programs: Safe load indicator (LMB),
configuration program with configuration picture, operation
program with operating picture, telescoping program with
telescoping picture, test parameter program, test system;
supporting force indication and work area limitation as an
optional feature
• Setting of the configuration program by convenient interactive
functions
• Safe and reliable acknowledgement of the configuration set
• Representation of all essential data by graphic symbols on
the operation picture
• With integrated wind force test
• Reliable cutoff device when exceeding the admissible load
moments
• Load capacity values for any boom intermediate length
• Winch indications for precise lifting/lowering of the load
LICCON configuration and
operation program
• Telescoping by single-stage hydraulic ram with hydraulic
driving tenons (patented internal interlocking system)
• Telescoping procedure controllable by convenient operator’s
guide on the monitor, precise approach of the interlocking
positions
• Telescopable loads are displayed on the LICCON operating
picture
• Rapid-cycle telescoping system with "automatic mode", i.e.
all-automatic telescoping to the required boom length
• Very compact and light-weight telescoping system, thus
increased load capacities, especially with long booms and
large radii
• Automatic cushioning in end positions during telescoping
and retracting for the preservation of the structural members
LICCON-assisted telescoping system
