Working Principle of Crack Fill Machine for Sale
Small asphalt crack sealing machine uses a liquefied gas heating system with heat-conducting oil circulation to quickly melt asphalt or crack-sealing glue. Driven by an asphalt pump, the material is discharged through the outlet under pressure to fill cracks. Pressure-injection sealing ensures tight adhesion between the material and crack walls, while flexible universal wheels track cracks precisely for a neat finish.
As materials like asphalt can solidify at low temperatures, the machine is equipped with a gasoline generator and a constant-temperature control system on the outlet pipe to prevent overheating and ensure smooth discharge.
Asphalt Crack Sealing Machine Application Scenarios
1. Municipal Road Maintenance
For minor (<3mm) and medium (3-10mm) cracks on urban roads, models like the YG-50L push-type asphalt crack sealing machine offer rapid repair, reducing road excavation and traffic disruption. Paired with asphalt crack sealing equipment-specific modified asphalt, it enhances anti-aging performance.
2. Highway Emergency Repairs
For cracked or lumpy highway surfaces, high-mobility models like the YG-100L (trailer-mounted) can treat 200-300 meters of cracks per hour, preventing damage escalation. With this equipment deployed urgently, road safety is ensured.
3. Parking Lots and Industrial Zones
For heavy-duty road cracks in parking lots or factories, large-capacity models like the YG-200L provide precise sealing to prevent oil leakage and subgrade corrosion, extending pavement life and meeting enterprise maintenance needs.
Crack Filling Equipment for Sale Components
- Heating System: Smart temperature controllers with heat-conducting oil circulation (or diesel burners) maintain ±5°C temperature consistency for even material heating.
- Power System: Diesel engines (or solar+batteries) supply stable power, paired with hydraulic/asphalt pumps for adjustable pressure.
- Hopper Unit: Stainless steel insulated tanks (some with stirring motors) prevent material solidification during heating and sealing.
- Control System: Integrated panels enable one-touch start, temperature presetting, and pressure adjustment, simplifying operation across models.
