MK 120-5.1E

Mobile construction crane

MK 120-5.1E - The solution for interfering edges.

The MK 120-5.1E offers an impressive crane performance on 5 axles. It closes the gap between the 4- and 5-axle mobile construction cranes and is therefore the perfect addition to our mobile crane portfolio.

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.

Ballast systems

Technology

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 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 makes starting on gradients easier. Move off safely and easily without rolling backwards.
Up to 90 % lower CO2 emissions in action.
Zero CO2 emissions when crane operations are powered by the electric motor.
With the integrated standard 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.
