LTR 1100 15
The LICCON working range
limiting system (optional)
• Relief for the crane driver by automatic
supervision of the working range
boundaries like bridges, roofs etc.
• Simple programming
• Four different limiting functions:
- Boom head height limiting
- Radius limiting
- Slewing angle limiting
- Border limiting
The LICCON working planner (optional)
• Computer program for planning,
simulation and documentation
of crane operations at the PC
• Display of all load charts belonging
to a specific crane
• Automatic search of a suitable crane by
input of the load case parameters load,
radius and hoisting height
• Simulation of crane operations with
drawing functions and display of support
forces
For functional and safe crane operation,
the LICCON computer system
The soft- and hardware of the mobile crane control is developed by Liebherr in-
house. The central point is the LICCON computer system (Liebherr Computed
Controlling). The system undertakes extensive information, control and super-
vision tasks. The control components have proved themselves in the diverse
climate conditions worldwide.
LICCON erection and operation program
• Operation programs:
- Overload limiter (LMB)
- Erection program with erection display
- Operation program with operation display
- Telescoping program with telescoping display
• Setting up of the erection status by comfortable dialog functions
• Display of all important data with graphic symbols
• Reliable cut-off at exceeding of the permissible load moments
• Winch display for exact hoisting/lowering of the load within centimetres
The data bus technology
Liebherr telescopic cranes completely linked through the data bus system. All
important electric and electronic components are equipped with own microproc-
essors and communicate over only a few data cables. For the special require-
ments of the telescopic cranes Liebherr has developed its own bus systems.
The data bus system technology improves the reliability, the comfort and the
safety of the drive and crane operation:
• Higher reliability due to much less electric cables and contacts
• Continuous self testing of the „intelligent sensors“
• Extensive diagnosis possibilities, fast fault finding
