horizontal and vertical operation with 2 control
panels on either side of the crane carrier, au-
tomatic outrigger levelling, electronic inclina-
tion display.

elling programmes. 1
st axle steered mechani-
cally and 2 nd and 3 rd axle steered electrohydrau-
lically depending on speed. Steering system
acc. to EC directive 70/311/EEC.
Brakes Service brake: all-wheel servo-air brake, all ax-
les are equipped with disc brakes, dual circuit.

wheels of axles 2 and 3.
Sustained-action brake: Exhaust retarder with
additional Liebherr braking system.
Anti-lock device in conjunction with anti skid
control.
Brakes acc. to EC directive 71/320 EEC.
Driver’s cab Spacious, steel made, corrosion resistant cab,
cataphoretic dip-primed, on resilient suspen-
sion with hydraulic shock absorbers, sound
and heat absorbing internal panelling acc. to
EC directive, safety glazing, operating and
control instruments, comfortably equipped
with unobstructed view of the road.
Electrical system Control of the electrical and electronical com-
ponents by modern data bus technique.
24 Volt DC, 2 batteries 170 Ah each, lighting
according to traffi c regulations.
Equipment Additional heating in the driver’s cab.
Crane superstructure
Slewing platform Steel-plate structure including tower pivot
bearing and connection to slewing ring. Con-
nection element to crane carrier is a Liebherr
slewing ring with internal toothing. Slewing
platform interlocking to undercarriage.
Power supply 48.0 kVA diesel-powered generator, tank on
superstructure; alternatively power supply via
building site main cabinet (external current
connection 63 A / 400 V); power distributor
1 x 32 A, 2 x 16 A, 3 x earthed sockets 220 V.
FC hoist gear Drives two drums, one for assembly and one
for hoisting. Continuous frequency-convert-
er control provides continuously variable hoist-
ing and lowering speeds, with precision posi-
tioning mode.
FC slewing gear Continuously variable operating speed, elec-
tronic wind load control and automatic load os-
cillation damping. Counter-current can be ap-
plied in absolute safety. Individually
adjustable rotational speed and torque control.
Trolley travel gear Trolley travel gear with frequency converter
and continuously variable speed.
Switchgear Programmable logic control system (PLC).
Telescopic tower Telescopic tower of lattice construction with
tower lock to slewing platform.
Jib Three-section jib, very high overhead assembly
curve so that only little space is needed for
erecting. Assembly takes place with a separate
winch and by engaging the jib assembly winch.
The jib is guyed by telescopic rods or cables.
Hydraulic jib slewing device (option).
Tensioning of trolley
and hoist ropes During the assembly and disassembly
processes the hoist and trolley ropes are
tensioned automatically.
Elevating cabin The operator’s cabin with its 360° view is of
elevating pattern with safety glass windows all
round and its own drive system for stepless
height adjustment.
Crane operator’s seat with the master switches
integrated into the armrests, thermostat-
controlled heating and ventilation, lighting and
a window wash/wipe system.
Electronic monitoring system EMS.
220 V socket.
Transport of crane
in erected position A very favourable centre of gravity permits
transport of the crane in its erected position.
0°- 15°- 30°- 45°
jib position Standard jib positions achieved by shortening
the rear jib guying, possible when the crane
is in operating condition, via radio remote
control or from the elevating cabin.
Equipment Equipment for construction site lighting:
4 x 1500 W halogen lights.
