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 angleofthefrontaxle.Above30km/hitwillbeadjustedtostraightdrivingandfixed
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 but-tons independently from the steering angle of the axle 1

Colourmonitor
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 controlledoutside of the cab.

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 the working floodlights as well as heater and air condi-tion controls.
