Mill Assist digital assistance system

Cost-optimisation in ECO mode

Smart assistance systems that aid machine operators and reduce their workload will shape the future of road construction, and are already field-proven realities at Wirtgen. In automatic mode, the Mill Assist Mill machine control system allows operators to choose one of three operating strategies – one of which is the ECO mode, which assures cost-optimised machine performance.

It sets parameters that consistently ensure the most favourable balance between milling performance and operating costs. This not only improves machine performance, but also considerably reduces diesel, water and pick consumption and CO₂ emissions. Mill Assist therefore makes a real contribution to sustainability in road construction.

Focus on sustainability

The demands on today’s cold milling machines are numerous: Alongside performance and quality, factors such as fuel and pick consumption and the reduction of local noise and CO₂ emissions also play a decisive role. In order to achieve the optimal settings for this, the operator must repeatedly check and readjust the individual machine parameters. Tasks that require considerable experience and extreme concentration. Preselecting the ECO mode operating strategy in Mill Assist significantly relieves the burden on the operator.

Mill Assist: cost-optimisation in ECO mode

Mill Assist offers three operating strategies:

  • ECO mode: cost-optimised

  • Power mode: performance-optimised, fast removal of the asphalt layer

  • Milling Pattern quality mode: for creating particularly finely milled surfaces

Depending on the operating strategy selected, the machine automatically adjusts the essential setting parameters.

ECO mode: Focus on cost-optimisation

ECO mode is always the right choice when fuel and pick consumption costs must be kept as low as possible. For example, on concrete construction sites where the hardness of the material to be milled inevitably leads to increased pick wear.

In ECO mode, the system continuously adapts machine operating parameters to the properties of the road pavement being milled. The optimisation of the parameters leads to a reduction of pick wear and the machine downtimes that would otherwise be required for replacing worn picks. Parallel to this, the fuel consumption is also reduced. This leads, on the one hand, to a working strategy that fulfils increasing demands for sustainability and, on the other hand, to considerably lower operating costs throughout the service life of a cold milling machine.

ECO mode: Easy to set

As the video shows, ECO mode can be activated simply by pressing the button. The system now determines the most cost-efficient settings – as can be clearly seen in the efficiency display on the control panel. As a quick look shows: at a low milling drum speed (green), the fuel consumption (white) and pick wear (red) are significantly reduced.

The highlights of ECO mode at a glance:

  • considerable reduction of diesel fuel consumption
  • lower carbon emissions
  • reduced pick wear
  • reduced noise emission due to lower milling drum speed
  • reduced machine operator workload

Mill Assist as a key component for optimised machine operation

Mill Assist is already a standard feature of the large and compact milling machines of the new F series, and is one of the key components for cost-effective, efficient and sustainable working processes. In automatic mode, the assistance system always selects the most favourable balance between milling performance and operating costs. It automatically adjusts the engine speed, milling drum speed, travel drive, water system and machine advance speed improves the overall performance of the machine. The machine operator is continually informed about the status of the work and the current efficiency of the machine. Options for the potential optimisation of milling parameters are displayed on the control panel and can be adopted if and when required.
