6 Control of Liebherr diesel engine (chassis) and
automatic transmission
• 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
