P1Roadsteering

The axle 1 is mechanically steered by the steering wheel. The axle 3 is actively steered depending on the speed and on the steering angle of the front axle. Above 30 km/h it will be adjusted to straight driving and fi xed

P2All-wheelsteering

The axles 2 and 3 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 2 and 3 are turned by the steering wheel to the same direction as the steering position of axle 1

P4Reducedswingout

The axles 2 and 3 are turned depending on the wheel turn of the 1. axle to minimize the back swing of the rear of the chassis

P5Independentrearaxlesteering

The axle 1 is steered by the steering wheel, the axles 2 and 3 are steered by push buttons inde-pendently from the steering angle of the axle 1

The new control generation - LICCON2

Colourmonitor

The readability of the data on themonitoroftheLICCON2control system in the crane cab is enhanced by the colour display. Warnings and crane utilization are considerably better recognized.

Supporting the crane

By use of the BTT the mobile cranecan be comfortably and safely sup-portedontheoutriggers.Enginestart/stop, speed regulation, electronic level display and automatic support level-lingareavailableasstandard.Option-ally also the supporting forces can be displayedontheBTT.

The new generation of the Liebherr crane control offers extended customer benefi ts and higher operational com-fort by additional possibilities of use. The base for this is the modern and future oriented control architecture with components, which are optimized regarding the comput-ing power as well as their capacities.

Touchdisplays

Belowthejoysticksintegrat-ed in the armrests the touch displays are installed, with which the various operational functions can be selected. This are beside others the drive and steering programs of the chassis, the axle sus-pension, the supporting of the crane, the adjustment of the working fl oodlights as well as heater and air condition controls.

Attaching and detach-ing of the hook block

TheBTT–Bluetooth terminal–offersthe crane driver the possibility to at-tach the hook block to or detach it from the front bumper within sight by remote control of the hoist winch and the luff-ing cylinder of the telescopic boom.
