The Nordic region is among the prime global movers in deployments of electric construction machines. Norway's capital city Oslo has made the bold decision to demand zero emissions on all its job sites from 2025. The Olav Vs Street and Klingenberg Street upgrade in Oslo that commenced in the autumn of 2019 is claimed to be the world's first zero-emission urban construction site. The project used electric construction equipment from Hitachi that is rebuilt for individual customer requirements by Norwegian company Nasta. The project utilised a 17.5-tonne Zeron ZE160LC electric excavator - the first to apply the PeakShaver + power management system. Nasta says that PeakShaver+ is a unique way to control power that allows large electric machines to cope with the power needed to run a machine that is half its size. The Olav Vs job site also used two nine-tonne electric Zeron ZE 85 hydraulic excavators from EAC (European Application Center), Hitachi's joint venture established in 2018 with Kiesel Technologie Entwicklung (KTEG) to develop electric construction machinery for sale in Europe. Nasta rebuilds Hitachi ZX160, ZX210 and the ZX350 machines, rebranded as Zeron ZE160LC Peakshaver+, Zeron ZE210LC and Zeron ZE350LC. |
