Variable steering concept
with „active rear-wheel
steering“

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

• Electric and electronic components are interconnected by
the latest data bus transmission technology

• Instead of the traditional electric wiring, data transmission
to the individual function blocks is performed digitally along
just a few data cables, thus improving reliability thanks to
a much-reduced number of contacts

• Bus systems of Liebherr’s own manufacture (LSB), specially
suited to mobile crane requirements

• Diesel engine and automatic transmission are controlled by
a CAN data bus. All-electronic driveline management reduces
fuel consumption and exhaust emissions

• The chassis and crane electrical systems and all cockpit
functions and the outrigger and boom sensor systems are
interconnected by 4 Liebherr system bus lines

• Control of the function blocks is by I/O modules programmed
by the Liebherr system bus lines. The control intelligence is
integrated into the central LICCON unit

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

• Programs for functional test of keyboard and display unit
and for testing the engine and transmission management
control units, additional Liebherr brake system, hydraulic
fan, hydraulic suspension and outrigger control panels

• This new data bus technology greatly enhances the
functionality and efficiency of the mobile crane

LTM 1160-5.1 LTM 1160-5.1

The LICCON test system

• This test system assists the servicing personnel to localize
faults in the crane sensory system quickly without the need
for measuring instruments

• Service work starts at the display screen:
troubleshooting takes only a few moments

• Faults are indicated by codes and descriptions
on the display screen

• Convenient interactive functions permit observation of all
inputs and outputs to and from the entire system; they can
be displayed in different forms on the display screen even
during crane operation. The system also visualizes the
position of the system’s individual sensors and actuators
and their functions

The LICCON work area
limiting system

• This reduces the crane operator’s workload, by monitoring
the work area limits, especially in situations where the
handling of loads requires close attention. Work areas can
be restricted to allow for buildings, bridges, roofs, high­tension power lines, pipelines or adjacent cranes. The
automatic work area limiting system (optional) can easily be
programmed. Four different limiting functions are practicable:

• Height limit for pulley head

• Radius limit

• Slewing angle limit

• Border limits

The LICCON work planner

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

• The 2D planner program permits buildings to be drawn, text
entered and a true to scale crane model represented, including
all movements within a simulated construction site

• The work planner creates greater clarity when preparing
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 winches, slewing gear and luffing and telescoping
movements by the LICCON computer system (PLC control)

• Four working movements can be performed independently

• 5-step preselection of lifting/lowering, luffing and slewing speeds

• Very rapid response rates when crane movements are selected

• Hoisting and slewing gear run in closed circuits. This permits
very sensitive lifting/lowering of loads and slewing movements.

When lowering loads, the energy generated is not converted
into heat but can be re-used for a second movement. This
saves fuel and the oil is exposed to less heat than when
operating in an open circuit
