Zero-emission machines cut noise during night construction in Copenhagen

At the end of 2019, especially low-noise construction machines and units were needed for a night job site in Copenhagen's pedestrian zone. When new cables were laid, nearly all the zero emission family by Wacker Neuson was used: from the battery-powered vibratory rammer to the electric wheel loader all the way to the mini-excavator EZ17e.

No compromises despite their emission-free working principle - this is the promise of zero emission solutions by Wacker Neuson. They proved this in the inner city of Copenhagen at the end of 2019. Here, new cables were laid in the pedestrian zone. The work was carried out predominantly at night and early in the morning, to prevent restrictions during shop opening hours and in order not to disturb area residents. Using the zero emission line by Wacker Neuson, the entire construction site was operated fully emission-free and with very low noise levels. 

First, the paving stones in the Copenhagen inner city were broken up with the fully electric zero tail excavator EZ17e; then, the soil was excavated. At no point did the rear protrude over the undercarriage, thanks to the compact design. The 1.5 metric ton excavator is in no way inferior to fuel-operated mini-excavators of the same class: All hydraulic functions possess the same performance as the conventional models. The excavated material was transported away using the electric wheel dumper DW15e with 1.5-metric ton payload. Moreover, the wheel loader WL20e was used for material transport on the construction site. 

After the cables were laid in the pedestrian zone, the ground was compacted with a battery-powered vibratory rammer and a vibratory plate. For larger areas, the battery-powered vibratory plate AP1850e was used, for confined spaces the battery-powered rammer AS50e. Both can be operated with the same lithium-ion battery, which is deployable as a module and can be changed in no time. This battery was specially conceived for the hard work conditions of the construction industry and delivers energy sufficient for all the work that compaction equipment needs to perform on an average workday.
