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

• The electric and electronic components are interconnected
by the latest data bus transmission technique

• Instead of the traditional electric wiring, the data transmission
to the individual function blocks is performed digitally just
by a few data cables, thus improved reliability due to
essentially less contacts

• Self-manufactured Liebherr bus systems (LSB), specially
adapted to the requirements of a mobile crane

• Diesel engine and automatic transmission are controlled by
a CAN data bus. The all electronic drive management reduces
fuel consumption and improves the exhaust gas emission

• The electric systems of the carrier and crane as well as of
all cockpit functions, the outrigger system and sensor system
of the boom are interconnected by 4 Liebherr system busses

• The control of the function blocks is realized by I/A modules
the programming of which is performed by means of the
Liebherr system busses. The control intelligence is integrated
into the LICCON central unit

• Comprehensive diagnostic facilities, quick error localization,
operating error display

• Test programs for functional test of keyboard and display
unit as well as for the test of the control units for engine
and transmission management, additional Liebherr brake
system, hydraulic ventilator, hydraulic suspension and
outrigger control panels

• The new data bus technique distinctively increases
functionality and efficiency of the mobile crane

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

LTM 1200-5.1 LTM 1200-5.1

The LICCON test system

• The test system assists the servicing personnel in quickly
localizing failures of the crane sensory system without the
need of measuring instruments

• The service starts on the display screen, troubleshooting
becomes a matter of minutes

• Occurring errors are indicated by error codes and error
descriptions on the display screen

• Convenient interactive functios permit the observation of all
inputs and outputs of the entire system by different
representations on the display screen even during crane
operation. It equally visualizes the allocation of the individual
sensors and actuators of the system and their functions

The LICCON work area
limitation system

• It relieves the crane operator, especially in situations where
the handling of loads requires his full attention, by controlling
the work area limits. Work areas can be restricted by buildings,
bridges, roofs, high-tension power lines, pipe lines or adjacent
cranes. The automatic work area limitation system (optional),
can easily be programmed. Four different limitation functions
are practicable:

• Height limitation of the pulley head

• Radius limitation

• Slewing angle limitation

• Limitation of edges

The LICCON work planner

• The LICCON work planner consists of a software program
on CD for planning, simulation and documentation of crane
applications on the display screen (optional)

• The 2D planner program enables the drawing of buildings,
to write texts and to represent a crane model true to scale
including the entire motions within a fictional
construction site

• The work planner permits the preparation of more transparent
offers, facilitates the briefing of crane operators and can be
run on a Laptop at the construction site

Electric/electronic PLC crane control with test system

• Control of the winches, slewing gear and the luffing and
telescoping motions by the LICCON computer system
(PLC control)

• Four working motions can be performed independent from one
another

• Speeds for lifting/lowering, luffing and slewing preselectable
by 5 steps

• Very short response rates at the activation of crane motions

• Hoist gear and slewing gear are operating within a "closed
oil circuit". This enables very sensitive lifting/lowering of
loads, or slewing. Moreover, during lowering of the load, the
generated potential engergy is not converted into heat but
can be re-employed, for a 2nd motion This saves fuel and
the oil is less thermically exposed than by operation within
the open circuit.
