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.

Technology

ECOmode

When ECOmode is activated, it controls the speed of the diesel motor automatically in line with the operating speed requested by the crane operator using the control lever. Depending on the model and the specific operating and usage conditions, this can help reduce fuel consumption.

ECOdrive

ECOdrive reduces the diesel engine's rpm and enables faster gear shifts, which can improve ride comfort and off-road performance. On the road, the control system uses engine torque as needed; as a result, fuel consumption can be reduced - depending on the model, driving style, and defined operating conditions - compared to driving without ECOdrive.

Hillstart-Aid

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

HVO ready

Suitable for operation with HVO.

Driver assistance systems

Driver assistance systems for extra safety on the road. All new mobile crane models are equipped with driver assistance systems that support the crane driver with additional „eyes“. They scan the environment and warn the crane driver to prevent accidents.

E-Technology

Mobile cranes with the E symbol feature an optional electric motor for crane operation. This allows for flexible switching between diesel and electro-hydraulic drive systems for crane operation. In purely electro-hydraulic crane operation, no motor-related exhaust gas emissions are produced.
