Product Description

Main Performance

🚧
Spraying Rate 0.2 – 3 kg/m²
📐
Max Spraying Width Up to 6 meters
🌡️
Heat Preservation Avg. temp. drop < 1 °C/h
A
All operations can be performed in the cab.
B
Asphalt spraying rate: 0.2 – 3 kg/m².
C
The width of spraying is adjustable. Each spraying nozzle can be controlled independently, with a maximum spraying width of 6 meters.
D
Spraying of asphalt is very even, and supports three-overlapping spray mode.
E
Asphalt application rate is computer-controlled and independent of truck speed.
F
Heating and heat-preserving systems use full circulation of thermal oil — safe, reliable, and fully automatic.
G
Thermal oil preserves heat for the asphalt pump and nozzles. No diesel washing needed after spraying — high-pressure air or thermal oil circulation keeps pipelines and nozzles clear.
H
Control system adopts modular design for easy maintenance and troubleshooting.
I
Equipped with a standby control system for operational redundancy.
J
Ensures normal machine operation even when the main control system fails.
K
Equipped with a flexible hand-spraying system for versatile application.
L
Excellent heat preservation — average temperature drop is less than 1 °C/h.
M
Loading and unloading asphalt is highly convenient. Asphalt can be filled through the manhole, sucked into the tank, or drained using the onboard pump.

Frequently Asked Questions

Q What is the asphalt spraying rate range of this machine?
The machine supports an asphalt spraying rate of 0.2 to 3 kg/m², allowing operators to precisely adjust output based on road surface requirements and project specifications.
Q Can the spraying width be adjusted, and how wide can it go?
Yes, the spraying width is fully adjustable. Each individual nozzle can be controlled independently, and the maximum spraying width can reach up to 6 meters, making it suitable for a wide range of road surface applications.
Q How does the thermal oil heating system work, and is it safe?
The heating and heat-preserving system uses full circulation of thermal oil, which maintains consistent temperature for both the asphalt pump and spraying nozzles. The system is fully automatic, safe, and reliable — and eliminates the need for diesel flushing after each use.
Q What happens if the main control system fails during operation?
The machine is equipped with a dedicated standby control system. In the event that the main control system fails, the standby system ensures continued normal machine operation without interruption, minimizing downtime on the job site.
Q How is asphalt loaded and unloaded from the machine?
Loading and unloading asphalt is highly flexible. Asphalt can be filled through the manhole, or it can be sucked directly into the tank using the onboard pump. Drainage is equally convenient with the same pump system.
Q Is the spraying rate affected by the speed of the truck?
No. The asphalt application rate is managed by a computer control system that operates independently of truck speed. This ensures consistent and uniform spraying regardless of vehicle movement, guaranteeing high-quality results across the entire surface.
