Zero Emission Mobility for NNRM
The Nasta ZE135 is the smaller sibling of the ZE210 and is based on the Hitachi ZX135US model. The operating weight of the machine is 15,7 tons and it is powered by a 74 kW electric motor. The driveline is essentially a downscaled version of the ZE210 and includes the “Battery+” technology for combined grid and battery operation.
The machine is equipped with a 200 kWh battery, which provides up to 6 hours of operation time without charging in between. The excavator can be DC-fast charged through a standard CCS2 inlet where available. With an AC-grid supply, the crawler excavator can be driven 24/7 with zero local emissions.
