Urban road construction projects such as "white-to-black" pavement reconstruction and emergency bridge repairs often require night construction — traffic restrictions during the day force construction teams to race against time. However, the "double disturbance" caused by traditional equipment has become an obstacle: a main road reconstruction project in a certain country was complained about 5 times in a row due to direct light shining into residents' windows and noise exceeding 70 decibels, eventually being forced to stop work for rectification, delaying the construction period by 10 days. Hengwang's electric mini crawler excavator with "night-specific design" has achieved "15 consecutive days of construction with zero complaints" through compliance breakthroughs, and its core parameters and measured data have been verified in multiple road construction projects.
Three major compliance red lines for night construction: How does Hengwang break through?
Night construction for road construction must meet three hard indicators simultaneously: light brightness ≤ 500 lumens (anti-glare), noise ≤ 60 decibels (in line with national standards), and adjustable light angle (to avoid direct irradiation of residential buildings). The customized design of Hengwang electric mini crawler excavator accurately targets these:
l Soft lighting system: Equipped with 450-lumen LED lights, the light is diffused, with brightness 10% lower than the limit. It also has a ±90° adjustable bracket, which can directional lighting according to the operation area to avoid direct light shining into residents' windows.
l Fully enclosed sound insulation structure: The engine compartment is equipped with double-layer sound insulation cotton, and the hydraulic system uses low-noise pumps and valves. The measured noise is only 55 decibels (equivalent to normal conversation volume), far below the national standard upper limit of 60 decibels.
l Zero-emission electric power: Pure electric drive avoids exhaust odor, and combined with low-speed mode during night operations, it further reduces body vibration noise, making it particularly suitable for road construction projects around residential areas.
lFrom "3 complaint-induced shutdowns" to "15 days without complaints": Comparison of measured cases
A "white-to-black" project of an expressway in a provincial capital city once fell into trouble: using traditional diesel mini crawler excavator for night construction, it was complained about 3 times in 3 days due to noise and light issues. Each shutdown for rectification took 2 days, resulting in direct losses exceeding 150,000 yuan. After replacing with Hengwang electric mini crawler excavator:
l The light angle is adjusted through the bracket, focusing only on the operation surface, with no glare feedback from residential buildings within 30 meters;
l The sound insulation design reduces noise to 48 decibels at 50 meters away, and resident complaints dropped to zero;
l Continuous night operations for 15 days without interruption, completing road base treatment 5 days in advance, saving 200,000 yuan in construction period costs.
Compliance of night construction for road construction has become a key variable in project progress. Hengwang electric mini crawler excavator controls "light, noise, and emissions" in three dimensions, turning night operations from a "complaint hot spot" into an "efficient window period".
