What's inside

Quickly ready:

The crane is erected in minutes and ready to operate in just a few actions.

A must-have for every city:

Working close to buildings or other disruptive edges are no problem with the various steep positions of the boom (at the press of a button).

Fully packed:

Over 60 % of the ballast can be transported within the 12-tonne axle load limit. Using the optional self-ballasting device, the additional ballast can be fitted independently.

Fully electric drives:

All drives and winches are powered by electric motors. This means that the crane’s operation is quiet, emissions-free and very economical.

Assistance systems:

Smart assistance systems for simple and safe crane operation.

Technology

ECOmode

ECOmode minimises both fuel consumption and noise emissions when operating the crane superstructure. The crane operator sets the required working speed using the control lever. The crane control system calculates the perfect engine speed for the diesel engine.

ECOdrive

ECOdrive makes the mobile crane significantly more comfortable and quieter by reducing the engine speed. Faster gearshifting delivers greater dynamic and traction offroad. On the road, the torque from the Liebherr diesel engine is used efficiently to minimise fuel consumption.

Hillstart-Aid

Hillstart-Aid makes starting on gradients easier. Move off safely and easily without rolling backwards.

HVO ready

Up to 90 % lower CO2 emissions in action.

Zero emissions

Zero CO2 emissions when crane operations are powered by the electric motor.

Self-ballasting

With the integrated self-ballasting unit, the crane can be ballasted quickly and efficiently without an additional auxiliary crane – for maximum flexibility and cost efficiency at your construction site.
