Global "green construction" policies are constantly tightening: the EU "low-emission zones" prohibit high-pollution equipment from entering; Berlin, Germany imposes a daily fine of 2,000 euros on non-compliant machinery; Paris, France even requires all municipal projects to use zero-emission equipment starting from 2024. Road construction projects using traditional fuel-powered equipment may face huge fines if not careful. A road renovation project in Germany was fined 150,000 euros and issued a 20-day work stoppage order due to excessive emissions from fuel-powered excavators — but the emergence of Hengwang electric mini crawler excavator is making such risks a thing of the past.
Two key aspects of environmental compliance: How does electric mini crawler excavator accurately meet standards?
Environmental compliance for road construction projects focuses on two core points: emission limits and pollution control. Hengwang electric mini crawler excavator HW10-3E perfectly adapts to global strict standards through "zero emissions + low noise" design:
· Breakthrough in emission standards: As a 1-ton rechargeable micro excavator, HW10-3E uses a 6.5KW permanent magnet synchronous motor, achieving zero exhaust emissions with electric power, directly meeting Euro 5 standards. It can enter EU low-emission zones without relying on exhaust gas purification devices. Its ternary lithium battery capacity reaches 150AH, with a battery life covering 8 hours of continuous operation, fully adapting to the daily construction needs of road projects.
· Noise pollution control: The hydraulic system and motor of HW10-3E are designed in coordination, with an operation noise of only 58 decibels. Combined with a shock-absorbing chassis, it meets the EU "quiet construction zone" (≤60 decibels) requirements. In road construction around residential areas in Paris, it can avoid daytime noise restrictions and reduce night operation complaints.
Specific cases: From Paris municipal engineering to Rotterdam port road
Case 1: Sidewalk renovation in Paris' 12th arrondissement
Project background: The renovation of sidewalks in central Paris requires simultaneous laying of underground cables. The construction area is adjacent to residential buildings, with strict environmental requirements — noise ≤ 60 decibels and must meet Euro 5 emissions.
Challenge: Traditional fuel-powered excavators have a noise of 85 decibels and excessive exhaust emissions, which may trigger a daily fine of 5,000 euros.
Solution: Use Hengwang HW10-3E mini crawler excavator, with its compact design of 2770mm in total length and 930mm in total width, which can operate flexibly on 1.5-meter-wide sidewalks.
Results:
l Zero-emission compliance: The equipment passed the inspection by the Paris environmental department, directly entering the construction area without additional emission permits;
l Silent operation: Residents reported "no obvious noise interference", with zero complaints during construction, completing 300 meters of cable trench excavation 2 days in advance;
l Cost optimization: Electricity costs are only 30% of fuel-powered machines, and potential fines are avoided, saving 12,000 euros for the project.
Case 2: Expansion of the connecting road to the Port of Rotterdam
Project background: The Port of Rotterdam needs to expand a 3-kilometer road. The EU "low-emission zone" policy requires construction equipment to have PM emissions ≤ 0.01g/kWh.
Challenge: Traditional diesel excavators have PM emissions of 0.5g/kWh, and the port's sandy terrain requires equipment to have a 30° climbing capacity.
Solution: Deploy Hengwang HW-13 mini crawler excavator (with optional Euro 5 emission configuration), with a maximum digging depth of 1630mm and a climbing capacity of 30°, adapting to the complex terrain of the port.
Results:
l Emission compliance: The equipment passed EU Stage V certification, with PM emissions of 0, smoothly entering low-emission zones for operation;
l Efficiency improvement: HW-13 has a maximum digging force of 7KN, with an hourly digging volume 15% higher than fuel-powered machines of the same tonnage, completing roadbed treatment 10 days in advance;
l Policy dividends: For meeting "green infrastructure" standards, the project received a 30,000-euro environmental subsidy from the Dutch government.
Environmental compliance for road construction projects has changed from an "additional requirement" to a "core competitiveness". Hengwang mini crawler excavator, with the technical advantages of "zero emissions, low noise, and high adaptability", makes road construction change from "fear of inspection" to "daring to show off".
