Mobile construction crane

MK 140-5.1E

The MK 140-5.1E mobile construction crane is a compact five-axle model that achieves a dimension of performance in this crane class that was previously reserved for equipment in higher axle classes. Thanks to the Hybrid Power Concept, which enables operation with site power, and the approval for HVO fuels, the crane is equipped for the future.

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 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.

Unique:

Vario Jib technology transforms a trolley jib into a luffing jib within minutes – with just one person.

Vario Jib:

In luffing jib mode, a hook height of 94.4 m and a radius of 65 m can be achieved, with a maximum tip load of 1 t.

Compact and manoeuvrable on 5 axles:

Thanks to various steering programs, manoeuvring in the tightest spaces is no problem. This crane fits into almost any gap in city centres.

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.
