• The electric and electronic components are interconnected
by the most modern data bus transmission technology
• Digital data transmission to the individual functional blocks
by just a few data cables instead of the conventional electric
wiring; thus increased functional reliability due to essentially
less contacts
• Self-manufactured Liebherr bus systems (LSB), specially
matched for the requirements of a mobile crane
• Diesel engine and automatic transmission are controlled by
means of 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 the crane as well as
all cockpit functions, the outrigger system and the boom
sensory system are interconnected by 4 Liebherr-system
busses
• The control of the functional blocks is realized by E/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 indication
• Test programs for functional test of the keyboard and display
unit as well as for the test of the control units of engine and
transmission management, Liebherr additional brake system,
hydraulic ventilator, hydraulic suspension and outrigger control
units
• The new data bus technology distinctively increases the
fuinctionality and efficiency of the mobile crane
Data bus technology for more
functionality and efficiency
