• Air-cushioned driver’s and co-driver’s seat with head rests,
driver’s seat with lumber support
• Auxiliary heater with engine preheating
• Safety belts for driver and co-driver
• Height and inclination adjustable steering wheel
• Heated and electrically adjustable rear mirrors
• Side panes with electric window lifters
• 3 automatic windscreen wipers with washing device and
intermittent control
• Delayed disconnection or interior lighting
• Various racks and boxes
• Radio preparation
Comfortable driver’s cab of
outstanding functionality
• Spring-mounted and hydraulically cushioned crane operator’s
seat with pneumatic lumber support and headrest
• Operator-friendly armrest-integrated controls, vertically and
horizontally adjustable master switch consoles and
ergonomically adjustable operating consoles
• Ergonomic control levers with integrated winch rotation and
slewing indicator
• Modern instrument supporting base with integrated LICCON
monitor, display of all essential operating data on the
LICCON screen
• Green-tinted heat-isolating front and side window panes
• Wiper/washer device for front window and skylight
• Auxiliary heater with engine preheating
• Various racks and boxes
• Radio preparation
• 1 working projector 70 Watt on the cabin front
Comfortable crane cab of
outstanding functionality
• 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
• The test system assists the servicing personnel in quickly
localizing errors of the sensor system without needing any
further measuring instruments
• Convenient interactive functions permit the observation of
all in- and outputs of the general system by different displays
on the monitor even during crane operation. It equally
visualizes the allocation of the individual sensors to the
system as well as their function and the terminals concerned
in the control cabinet
• The table of contents enables the display of the contents
and the state of development of the program modules as
well as the load charts on the monitor
• The service starts on the monitor, error detection becomes
a matter of seconds
The LICCON test 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 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 area
limitation system
• The LICCON work planner consists of a software program
for planning, simulation and documentation of crane
applications on the monitor
• The 2-D planner allows to draw buildings, to write texts and
to represent a crane model true to scale including its motions
within a fictional construction site
• The work planner enables the preparation of more transparent
offers, facilitates the briefing of the crane operators and it
can be run on a laptop at the construction site
