Outstanding boom technology
Powerful carrier drive
• Focal points of the new boom technology:
- oviform boom profile
- patented internal interlocking system of
the telescopes
- automatic telescoping system
• Telescopic boom with electronically controlled telescoping
system
• Boom bearings of low maintenance polyamide
slide blocks
• Outstanding lifting capacities, e.g.
161 t at 10 m radius
77 t at 20 m radius
37.4 t at 40 m radius
21.4 t at 60 m radius
13 t at 80 m radius
3.6 t at 108 m radius
• 8-cylinder Liebherr turbo-charged Diesel engine D9508 A7
of 500 kW/680 hp, exhaust emissions acc. to 97/68/EG stage
3 and EPA/CARB Tier 3, energy-saving, emission-optimized,
robust and reliable, electronic engine management
• Automated gear system ZF-TC-TRONIC with converter
and retarder, 12 forward and 2 reversed speeds, automated
control
• Transfer case
• Robust crane axles, welded design
• Max. driving speed 80 km/h
• In addition to the service and parking brakes, the following
sustained-action brakes: Exhaust brake with Liebherr auxiliary
brake system by valve control, intarder filled to transmission,
Telma-type eddy current brake on 4th axle
Data bus technique revolutionizes
crane electric system
• The data transmission to the individual functional blocks is
realized digitally by just a few data cables instead of the
traditional electrical wiring. Thus, increased functional reliability
and essentially less contacts
• Self-manufactured bus systems, especially adapted to the
requirements of a mobile crane
• The vehicle and crane electrics with all cockpit functions, the
outrigger system and the boom sensor system are
interconnected by 6 Liebherr system busses
• Comprehensive diagnostic facilities, quick
localization of errors
• The new data bus technique provides a distinctive increase
in functionality and efficiency

Outstanding carrier technology for
road and off-road application
• Weight optimized and low maintenance axles of high-tensile
steel; perfect track keeping and lateral stability due to special
control linkage arrangement
• Steering knuckles mounted on steel bearings, thus bearing
failures are practically ruled out
• The perfected and robust axles are manufactured in large
series and are part of the trouble-free components of a mobile
crane
• The cardan shafts in the axles are maintenance-free and are
safely located within the axle body. 70° diagonal toothing
enables easy and fast fitting by just a few screws.

Weight-optimized steel structure
• Carrier, superstructure and telescopic boom in light-gauge
design, calculated by the F.E.M. method, weight-optimized
and of particular torsional rigidity
• Tensile property of material with high safety factors through
the application of STE 960 (960 N/mm2) for all supporting
members
Crane drive with proved
components
• 6-cylinder Liebherr turbo-charged Diesel engine type D936L
A6 of 240 kW/326 h.p, exhaust gas emissions in accordance
with the directives 97/68/EG stage 3 and EPA/CARB Tier 3,
electronically controlled engine speed, engine located laterally
to the rear of the superstructure
• Pump distribution gear with 4 servo-controlled axial piston
variable displacement pumps operating in a closed oil circuit
for winches 1, 2, 3 and slewing gear; 2 servo-controlled
double axial piston variable displacement pumps in an open
oil circuit for luffing/telescoping; oil cooler within the hydraulic
oil circuit
Crane and road-preserving
Niveaumatik suspension
• Maintenance-free suspension rams, free of lateral forces and
protected by synthetic tubes
• Level adjustment (suspension set to ”travel mode”) can be
performed automatically by push-button control from any
position
• Stable cornering ability due to cross mounting of the hydraulic
suspension
• Axle locking system (locking of the suspension for travelling
with equipment) integrated into the suspension ram and
controllable from the driver’s cabin
