ZERON is a series of all-electric excavators from Nasta. The excavators have lower operating costs than traditional machinery and are so quiet that they can be used in noise-regulated areas.
About 40 per cent of global greenhouse gas emissions come from the construction industry, according to the UN. Yet the world needs to build more and better infrastructure.
One of the major drivers of construction emissions is heavy machinery running on fossil fuels. Electric alternatives have until now been a rarity.
ZERON – or “Zero Emission by Nasta” – is a climate-friendly solution for construction projects.
The ZERON series of all-electric construction machinery includes the ZERON ZE160LC, a 17.5-metric-ton tracked excavator. This is the first machine with the unique power management system PeakShaver +, which allows it to operate at maximum capacity with only half of a regular power supply. Powerful batteries of 42kWh complement the electricity supply at times when extra power is needed, while also letting the excavator operate for half an hour without any power connection at all.
The ZERON’s power rating is 86 kW, with a recommended bucket size of 0.9 m³. The excavator’s maximum reach is 8.87 metres, while maximum digging depth is 5.98 metres and maximum dumping height is 6.17 metres.
The machine is equipped with a hydraulic quick coupler, a tilt rotator, and a variety of buckets and selector grabs. It can easily be fitted with other equipment such as a compactor, breaker and more.
The ZERON series of excavators are completely emission free in operation, with no emissions of CO₂, NOx, carbon monoxide, particulate matter or unburned fuel. They are thus climate-friendly and do not cause local air pollution.
The machinery, moreover, makes little noise and does not disturb its immediate surroundings. This means – conditions permitting – that construction can take place even at noise-regulated times of the day.
The excavator can operate continuously when connected to a 400-volt/63-amp power supply, without needing to stop for refuelling or to replace engine oil. It consumes substantially less energy than a similar machine with an internal combustion engine and will therefore offer significantly lower operating costs.
Over the next 15 years, USD 95 trillion will need to be invested in infrastructure, according to the Global Alliance for Buildings and Construction. At the same time, emissions must be cut dramatically. Zero-emission machinery will thus become a necessity across the globe.
Nasta has already delivered zero-emission machinery to the world’s first 100 per cent emission-free urban construction project: an upgrade of inner-city streets in Oslo, Norway. The company was established in 1929 and is one of Norway’s largest suppliers of excavators.
