The LICCON test system
• The test system assists the servicing personnel in quickly
localizing failures of the crane sensory system without the
need of measuring instruments
• The service starts on the display screen, troubleshooting
becomes a matter of seconds
• Occurring errors are indicated by error codes and error
descriptions on the display screen
• Convenient interactive functions permit the observation of
all inputs and outputs of the entire system by different
representations on the display screen even during crane
operation. It equally visualizes the allocation of the individual
sensors and actuators of the system and their functions.
The LICCON work area
limitation 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 power lines, pipelines 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 planner
• The LICCON work planner consists of a software program
on CD for planning, simulation and documentation of crane
applications on the display screen (optional)
• The 2D planner program enables the drawing of buildings,
to write texts and to represent a crane model true to scale
including the entire motions within a fictional construction
site
• The work planner permits the preparation of more transparent
offers, facilitates the briefing of crane operators and can be
run on a Laptop at the construction site
• Powerful, 6-cylinder Liebherr turbo-charged diesel engine
type D846 A7, 370 kW/503 hp, exhaust gas emissions
correspond to the directives 97/68/EC Stage 3 and
EPA/CARB Tier 3, robust and reliable, modern and
electronically-controlled engine management
• ZF power shift gear with automated AS-TRONIC control
system. ZF intarder fitted directly to the gear unit, 12 forward
and 2 reverse gears, automated control, reduced fuel
consumption due to a high number of gears
• 2-stage, robust transfer case with lockable transfer differential,
creeping speed 0.78 km/h
• Drive 10 x 6, axles 2, 4 and 5 driven
• Drive 10 x 8 (optional), axles 2, 4 and 5 driven, axle 1 can
be activated for off-road displacement
• Weight-optimized, robust, low-maintenance axles, perfect
track keeping and lateral stability due to special arrangement
of the steering knuckles; maintenance-free axle struts, steel
and rubber mounted
• Maintenance-free drive shafts; quick and easy fitting due to
70° diagonal toothing
• Hydropneumatic ”Niveaumatik” suspension, program-
controlled for ”setting crane on outriggers”, ”crane
displacement with equipment” and "crane displacement on
the road", suspension travel +150/-150 mm
• Lateral force released and maintenance-free suspension
rams, piston rods protected against damage
by synthetic pipes
• Sustained-action brakes:
Engine brake as exhaust retarder with Liebherr additional
brake system (ZBS), intarder on gear, optional Telma-type
eddy current brake
• Service brake:
All axles fitted with air disc brakes, high braking performance,
long maintenance intervals, rapid-change brake linings
Modern drive concept
• Overall length 15.52 m, carrier length 13.3 m
• Large overhang angles of up to 20°
• Smallest turning radius of 11.01 m with all-wheel steering
• Rear counterweight radius only 4.85 m
• 60 t total weight (axle load 5 x 12 t)
• Choice of 3 tyre sizes
14.00 R 25 carrier width 3 m
16.00 R 25 carrier width 3 m
20.5
R 25 carrier width 3.1 m
