Operating Problems

Problems It Solves

Inconsistent asphalt application from manual or uncontrolled spray systems
Overheating or cooling of asphalt during transport due to poor thermal control
Limited spray width adjustment requiring multiple passes on narrow or wide roads
Nozzle clogging and pipe blockages from residual asphalt after use
Lack of dual control systems leading to unsafe operation during spraying
High downtime due to complex maintenance on older or non-integrated asphalt spreaders

Where It Works

Application Scenarios

Municipal road maintenance teams patching potholes and sealing cracks on urban streets

Build Materials

Materials

Carbon steel tank with internal insulation for heat retention
Heat conduction oil system for consistent asphalt temperature control
Stainless steel piping and nozzles for resistance to asphalt residue buildup
Aluminium alloy components on control panels and access doors for corrosion resistance
Rubber seals on doors and joints to prevent asphalt leakage and dust ingress
High-grade hydraulic hoses and fittings rated for asphalt temperatures

How It Is Built

Manufacturing Process

Chassis is received from Sinotruk and verified against the tank and system layout drawings
Tank shell is cut, formed, and welded with internal baffles and insulation layers
Tank is pressure tested and inspected for leaks before internal coating is applied
Heating system and heat conduction oil lines are installed and tested for integrity
Pump, piping, and nozzle array are assembled and aligned with the control system
Control panels and dual interface (cab and rear) are installed and calibrated
Spray system is tested with water and then with heated asphalt to verify flow and control
Final inspection includes full system operation, temperature control, and rinsing function
Truck is cleaned, painted in customer colour (free), and prepared for shipment

Testing

Quality Control

All tanks are pressure tested and inspected for leaks before final assembly
Heating system tested at maximum operating temperature for 24 hours
Spray system tested with full range of flow and width settings
Control system verified for dual interface operation and fail-safe response
100 percent test before delivery, including photos and videos sent to buyer
Temperature control system validated to maintain asphalt within 2 degrees per hour

Build to Order

Customization Options

Tank capacity can be adjusted to match project-specific asphalt volume needs
Left or right hand drive chassis selected to match local traffic regulations
Tank colour and logo applied free of charge to match fleet livery
Spray system can be upgraded from hand-controlled to full computer-controlled
Nozzle configuration and spray pattern adjusted to suit specific road surface types
Manufacture to customer supplied technical drawings and specifications

Comparison

How It Compares With the Alternatives

6m3 manual asphalt spreader	Carries less asphalt and requires more refills but is easier to maneuver in tight urban spaces
Full asphalt paver machine	Higher initial cost and complexity but provides continuous, uniform paving; not suitable for spot patching
Standard asphalt tanker with hose	No temperature control or precise spray regulation; prone to uneven application and clogging

Operating Notes

Use Guide

Confirm left or right hand drive chassis at order stage to match local road rules
Fill asphalt only through the designated inlet and avoid overfilling the tank
Set heating system to maintain asphalt temperature within safe operating range
Use computer control system to adjust spray width and flow rate based on vehicle speed
Engage automatic blowing device after each spraying session to clear pipes
Rinse system with solvent or water after use to prevent asphalt residue buildup
