In the center of Munich is one of the city’s most elaborate construction sites. A new mobility hub has been under construction for a few years now with the second suburban railway line, the new station building, and the shell for a new subway line. Necessary preparations were made in 2024, including reinforcement of old foundations through the incorporation of a pile head beam. This work took place during regular station operation – and was almost noise-free and without exhaust emissions in the underground. This was made possible by zero emission construction equipment and machines, which the executing contractor ZECH Bau SE rented for this construction phase.

The challenges in the underground at the station are enormous:

• Confined spaces
• Lack of fresh air supply in the tunnel
• Passenger traffic just a few meters away

This work would hardly be feasible with conventional diesel-operated machines. An expensive ventilation system would be absolutely necessary. Thanks to the zero emission machines from Wacker Neuson, these additional costs could be avoided – a clear advantage in terms of efficiency and budget.

The contractor ZECH Bau SE relied entirely on the electric construction machines and construction equipment from Wacker Neuson. From mini-excavators and telehandlers to compaction equipment – all machines are purely electric and prove that performance and sustainability work perfectly together. Another benefit: Noise emissions are reduced to a minimum. This generates a significantly more pleasant working environment for the operators and workers. And passersby barely noticed the construction site.

Two models of the fully electric EZ17e, a compact mini-excavator without rear projection, were in long-term application. Over 600 cubic meters of material had to be moved at the construction site – a mammoth task in narrow tunnels.

The EZ17e impressed here through:

• Full performance like its diesel-operated counterpart
• Minimum noise level – optimal for noise-sensitive areas
• Zero exhaust gas emissions, thanks to which the air quality in the tunnel remained good

Even the TH412e was continuously in use. Smaller than two by two meters, the fully electric telehandler fit perfectly through the narrow passageways of the subbase at the train station. It reliably took care of material transport and demonstrated how versatile emission-free machines are.

The BatteryOne battery powers the compaction equipment – the Battery AS62e and the battery-operated vibratory plate APU3050e – with full performance. Particularly practical: The battery can be switched between different machines in a matter of seconds. The simple operation – starting at the push of a button – and its running time, which lasts an entire working day, were also impressive in every aspect.

With its zero emission portfolio, Wacker Neuson shows that sustainable construction sites are no longer a vision for the future – but a reality. The zero emission construction equipment and machines at Munich main train station impressed with their low noise level and emission-free working manner, and prove that electric machines and equipment are in no way inferior to their diesel counterparts when it comes to performance, flexibility, and economic efficiency.
