Axles 3, 4 and 5 incorporated into active rear-wheel steering
system; 5 steering methods can be preselected as fixed
programs (P):

P1: On-road steering
Axles 1 and 2 are steered mechanically from the steering
wheel, with hydraulic power assistance. Axles 3, 4 and 5 are
steered actively by a speed-dependent method according to
the front wheel lock angle. Above 30 km/h, axles 3 and 4 are
returned to the straight-ahead position and fixed. Above
60 km/h, axle 5 is also fixed in the straight-ahead position.
The change in steering lock angle according to road speed
results in precise, stable driving road behavior at higher speeds,
reduced tire abrasion and much-improved maneuverability

P2: All-wheel steering
Axles 3, 4 and 5, depending on the wheel lock angle of axle 1,
are turned by means of the steering wheel so that the smallest
turning-circle radius can be obtained

P3: Crabwise steering
Axles 3, 4 and 5 are turned into the same direction as axles 1
and 2 by means of the steering wheel

P4: Steering without superstructure
projection when turning
Axles 3, 4 and 5 are turned in accordance with the wheel lock
angle at axle 1, so that the rear of the vehicle does not project
when cornering

P5: Independent rear-axle steering
Axles 1 and 2 are turned by the steering wheel, axles 3, 4 and 5
are steered independent of the lock angle at 1 and 2 by
pushbuttons; at the same time the lock angle at axle 3 is
adapted to suit the actual situation

• A failure in the rear-axle steering shuts it down; the rear axles

are set to the straight-ahead position by centering rams

• Two independent hydraulic circuits with wheel-driven

and engine-driven hydraulic pumps for the maximum
level of safety

• Two independent control processors (by way of existing

input/output modules) and diversified sensor system

• The entire know-how for the active rear-wheel steering

comes from Liebherr

Variable steering concept
with „active rear-wheel
steering“

• Standard application programs: safe load indicator (LMB),

setting-up program with image, operating program with
image, telescoping program with image, test parameter
program, test system; support load indication and work area
limiting as optional features

• Setting-up program values selected by

convenient interactive functions

• Safe and reliable acknowledgement of the setting-up values
• All essential data shown by graphic symbols

on the operating image

• With integrated wind force measurement
• Reliable shut-down device if admissible load

moments are exceeded

• Load capacity values for any intermediate boom length
• Winch displays for precise lifting/lowering of the load

LICCON setting-up and
operating program

• Telescoping by single-stage hydraulic ram with hydraulic

actuating pins (patented internal locking system)

• Telescoping controllable by convenient operator

guidance on the monitor screen, precise approach
to pin locking positions

• Loads that can be telescoped are shown on the

LICCON operating display

• Rapid-cycle telescoping system with automatic mode, i.e.

all-automatic telescoping to each desired boom length

• Extremely compact, lightweight telescoping system for

increased load capacities, especially with long booms and
large radii

• Automatic damping at limit positions during telescoping and

retracting, to minimize loads on structural members

telescoping system
