Variable steering concept
Active rear axle steering
The rear axles are electro-hydraulically actively steered depending on the speed andthesteeringangleofthefrontaxles.5steeringprogrammes(P)areprese-lectable by push button.

P1Roadsteering
The axles 1 and 2 are mechanically steered by the steering wheel. The axle 4 is actively steered depending on the speed and on the steering angle of the frontaxle.From30km/hitwillbead-justed to straight driving and fixed. Axle 3 is none steered for road driving.
P2All-wheelsteering
The axles 3 and 4 are turned by the steering wheel depending on the steering angle of the front axle to provide for the smallest turning radius.
P3Crabsteering
The axles 3 and 4 are turned by the steer-ing wheel to the same direction as the steering position of axle 1 and 2.
P4Reducedswingout
The axles 3 and 4 are turned depending on the wheel turn of the front axles to minimize the back swing of the rear of the chassis.
P5 Independent rear axle steering
The axles 1 and 2 are steered by the steering wheel, the axles 3 and 4 are steered by push buttons independently from the steering angle of the axles 1 and 2

The second control generation LICCON2 is the result of a continuous development by the Liebherr specialists and enables the adaption to the con- stantly increasing demands of the markets due to its modern and future oriented control.
The data bus technology
Liebherr mobile cranes are completely interlaced by the data bus system. All important electric and electronic components are equippedwith ownmicro-processorsandcommunicatewitheachotherbyonlylimiteddatacables.Forthe special demands of the mobile crane Liebherr has developed own data bus systems (LSB-Liebherr-System-Bus).Thedatabus technology improves thereliability,thecomfortandthesafetyforroaddrivingandcraneoperation:

LICCON2 – safe and comfortable
Colour monitor
The readability of the data on the monitor of the LICCON2controlsysteminthe crane cab is enhanced by the colour display. Warn-ings and crane utilization are considerably better recog-nized.
Wireless remote control (option)
All crane motions can be controlled outside of the cab.

•Freeviewandclosenesstotheload
•Preventionofcommunicationerrorsbetween the crane driver and the job site personnel
Attaching and detaching of the hook block
TheBTT–BluetoothTerminaloffersthecranedriverthepossibility to attach or detach the hook block at the front of the vehicle within sight, as the hoist winch and the luff-ing cylinder of the telescopic boom are remote controlled.
Touch displays
Belowthejoysticksintegrat-ed in the armrests the touch displays are installed, with which the various operational functions can be selected. These are beside others the drive and steering programs of the chassis, the axle sus-pension, the supporting of the crane, the adjustment of theworkingfloodlightsaswell as heater and air condi-tion controls.
