The new control generation – LICCON2

Colour monitor

The readability of the data on themonitoroftheLICCON2control unit in the crane cabin is improved by the colour display. Warning indications and crane utilisation are more clearly visible.

The new generation of the Liebherr crane control offers an extended customer value and higher control comfort by additional user possibilities. The base for this is the modern and future oriented control architecture with components,whichhavebeenoptimizedforcomputingpower and capacity.

Touch display
