Liebherr's Mobile Crane Control System Assists Operators

The new generation of the Liebherr mobile crane control system LICCON (Liebherr Computed Controlling) improves the operator's value and comfort while adding additional user possibilities. The new model cranes LTM 1050-3.1, LTM 11200-9.1 and LTM 1150-6.1 are already equipped with the new LICCON control. Components have been optimized regarding the computing power and capacity.

Mobile cranes with the new control system are immediately recognized by the color screen, the touch display below the joysticks and the mobile control and display unit Bluetooth terminal (BTT). The color display of the data on the LICCON monitor in the crane cabin enhances the readability and clarity, so warnings and the crane utilization are better recognized. Below the joysticks, touch displays are provided for comfortable activation of the different operational functions. Other features include the carrier drive and steering programs, the suspension system, the setting up of the crane on the outriggers, the adjustment of the working floodlights, and heating and climate control.

With the Bluetooth terminal, the crane can be comfortably and safely supported. Engine start/stop function, control of revolutions, electronic inclination display, and automatic leveling during setup on the outriggers are available as standard. As an option, the outrigger forces can be displayed.

By means of the BTT, the crane driver can attach and detach the hook-block to and from the front bumper within view by remote control of the hoist winch and the luffing cylinder of the telescopic boom. This new function is a considerable relief for the driver, because up to now he only could view the hook-block through a mirror or an assistant was necessary for guidance.

Depending on the crane type and the execution, the BTT can be programmed with additional functions like mounting of swing-on extensions or counterweights. On the LTM 11200-9.1 the BTT is also used for assembling the boom. During driving the BTT is plugged in the driver's cockpit and serves to display information such as mileage and working hours.
