� The electric and electronic components are interconnectedby the latest data bus transmission technique

� Instead of the traditional electric wiring, the datatransmission to the individual function blocks is performeddigitally just by a few data cables, thus improvedreliability due to essentially less contacts

� Self-manufactured Liebherr bus systems, specially adaptedto the requirements of a mobile crane

� Carrier engine, AS-TRONIC gear, intarder and enginebrake, as an integrated automated power train, arecontrolled via a CAN data bus. The fully electronic drivemanagement reduces fuel consumption and improves theexhaust gas emission

� The crane engine is controlled via a CAN data bus� The carrier and crane electric systems, including all

cockpit functions, the outrigger system and the boomsensor system are interconnected by 3 Liebherr systembusses

� The activation of the function blocks is realized byI/O modules, the programming of which is performed viathe Liebherr system busses. The control intelligence isintegrated into the LICCON central unit

� Comprehensive diagnostic facilities, quick error detection,operator error display

� Test programs for the functional test of the keyboard anddisplay unit as well as for the check of the control devicesfor engine and gear management, Liebherr additionalbrake system, hydraulic ventilator, hydraulic suspensionand outrigger control panels

The LICCON work planner.� The LICCON work planner consists of a software

program on diskettes for planning, simulation anddocumentation of crane applications on the monitor

� The 2-D planner allows to draw buildings, to write textsand to represent a crane model true to scale includingits entire motions within a fictional construction site

� The work planner enables the preparation of moretransparent offers, it facilitates the briefing of the craneoperators and it can be run on a laptop at the constructionsite

The LICCON test system� The test system assists the servicing personnel in

quickly localizing errors of the sensor system of thecrane without needing any further measuringinstruments

� Convenient interactive functions permit the observationof all in- and outputs of the general system by differentdisplays on the monitor even during crane operation.It equally visualizes the allocation of the individualsensors to the system as well as their function and theterminals concerned in the control cabinet

� The table of contents enables the display on the monitorof the contents and the state of development of theprogram modules as well the load charts

� The service starts on the monitor, error detection becomesa matter of seconds

The LICCON work arealimitation 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 berestricted by buildings, bridges, roofs, high-tensionlines, pipe lines or adjacent cranes. The automatic workarea limitation system (optional) can easily beprogrammed. Four different limitation functions arepracticable:

� Height limitation of the pulley head� Radius limitation� Slewing angle limitation� Limitation of edges

Electric/electronic PLC crane control and testsystem.� Control of the winches, slewing gear as well as luffing

and telescoping motions via the LICCON computersystem (PLC control)

� Four working motions can be performed independentof one another

� Speeds of hoisting/lowering, luffing and slewingpreselectable by 5 steps

� Very short response rate when initiating the cranemotions

� Hoist gear and slewing gear are operating within a“closed oil circuit”. This enables particularly precisehoisting, lowering or slewing of the load. Moreover, thepotential energy generated during the lowering of aload is not converted into heat but can be re-employedfor a second motion. This offers the particular advantagein saving fuel and reduced thermal exposure of the oilthan in an open circuit.

� Functional test of all essential components by theLICCON test system
