FND-DG400
1. Unique Product Advantages
FND-DG400 is a 400L self-driving asphalt crack sealing machine. Its core competitive merit lies in built-in electric driving system. No extra trailer or towing truck is required for site-to-site relocation. Equipped with automatic driving control, it can reach maximum travel speed of 55km/h with approx. 60-km driving range. Operators can drive the machine directly between scattered working spots on construction sites or short-distance road sections, saving costs and waiting time for towing vehicles. It fits maintenance projects with frequently-changed working locations perfectly.
This machine supports dual-power supply modes. The on-board Honda gasoline generator enables independent power supply for field sites without grid access. Meanwhile, external municipal mains power input interface is reserved. Users can switch between two power sources flexibly: generator for remote wild zones and city mains for urban construction sites to cut fuel consumption and operating expense.
It adopts Japan Omron dual-digital LCD temperature controller to monitor and adjust temperature of thermal-conducting oil, hot-pour sealant and heating hose separately with accurate visual readout. Hot-melting kettle works via indirect thermal-oil heating. Specially-designed combustion chamber delivers 45-degree downward flame for full combustion and high heat efficiency, preventing sealant carbonization and over-burning.
Human-oriented safety design adopts yacht-grade trailer rear axle to lower overall machine height. Low-position filling inlet comes with anti-splash baffle for safer feeding and anti-scald protection. Electric control switch is integrated on the sealing-gun handle, allowing operators to start-stop material pump locally to reduce sealant waste. The discharge hose supports 270° free rotation with excellent anti-bending performance, adapting to both transverse and longitudinal pavement cracks. Imported variable-speed electric agitator features simple structure and easy maintenance. Built-in LED directional warning lights improve safety during lane-occupying road repair work.
FND-DG400 can cooperate with independent crack router to finish crack pre-processing. Routing width is adjustable according to actual conditions: narrow routing mode for fine hairline cracks on municipal urban roads and county highways; wide routing mode for deep, severe cracks on national & provincial highways. After router cleans debris inside cracks, this self-propelled sealing machine can start crack sealing work directly.
