Originating from Chang'an University's Mechanical Dynamics Laboratory, our designs are rooted in deep thermo-fluid mechanics and combustion engineering, ensuring optimal heat preservation and binder flow dynamics.
Our intelligent bitumen spray tankers utilize customized proportional hydraulic transmission and multi-stage electronic control system integrations, holding national invention patents in mechanical-hydraulic optimization.
Recognized as a Shaanxi Provincial High-Tech Enterprise since 2006, every tanker chassis, thermal oil heating tube, and pneumatic spray bar undergoes 100% pressure, thermal efficiency, and spray uniformity testing.
Global highway departments are shifting budget allocations from full-depth pavement reconstruction to early preventative maintenance strategies such as micro-surfacing, chip sealing, and ultrathin asphalt overlays. High-precision bitumen spray tankers are the key asset required to deliver controlled 0.2 kg/m² to 2.5 kg/m² binder distribution without streaking or bar overlap defects.
With increasing use of Polymer Modified Bitumen (PMB), SBS-modified asphalt, and crumb rubber asphalt, conventional gravity-fed distributors are obsolete. Modern contractors demand high-capacity internal burner heat exchangers, heat-traced asphalt pumps, and triple-filtered pneumatic nozzle systems to handle viscosities up to 3000 cSt at 180°C.
Integrated Doppler radar velocity sensors feed real-time truck speed back to the industrial PLC controller. The variable displacement hydraulic pump automatically adjusts asphalt pump output to maintain a pinpoint accurate application rate regardless of vehicle speed fluctuations.
Equipped with automatic diesel burners and seamless U-type heat exchanger tubes combined with continuous thermal oil jacket circulation. Thermal oil flows through the pump body, spray bar, and nozzles, completely eliminating asphalt clogging prior to spraying operations.
Pneumatically controlled fan-shaped spray nozzles feature precise 15-degree angling to achieve perfect double or triple overlap patterns. Spray width can be dynamically adjusted from 0.5 meters to 6.0 meters inside the driver cab.
In regions such as Central Asia, the Andes, or high-altitude plateaus, ambient temperatures drop rapidly, causing conventional asphalt pumps to freeze instantly. HEM spray tankers utilize 100mm high-density rock wool thermal insulation with aluminum stainless steel jacket encasement, keeping internal binder temperatures warm up to 18 hours without burner re-ignition.
Deploying emulsion asphalt (CRS-1, CMS-2) in Southeast Asia or Equatorial Africa requires active moisture separation and precise temperature bounds (60°C–70°C) to prevent emulsion breaking inside the tank. Our closed-loop thermic oil controls avoid localized thermal degradation.
Featuring low-noise hydraulic drives, quick-response pneumatic cylinder valve manifolds, and high-intensity LED illumination booms, enabling precision tack coating during tight 4-hour night maintenance windows on international airport runways.
Mounted on reinforced heavy-duty 4x2, 6x4, or 8x4 truck chassis (HOWO, SHACMAN, FAW, DONGFENG, ISUZU, MAN compatible), built to navigate unpaved haul routes, extreme gradients, and dust-dense mining corridors.
From tank shell bending, automated robotic seam welding, thermal oil loop pressure testing to truck chassis mounting, 92% of structural and mechanical assembly occurs under one 50,000m² factory roof.
We combine heavy-duty Chinese chassis structural durability with tier-1 international hydraulic parts (Sauer-Danfoss, Rexroth valves, Parker fittings, Riello burners), offering optimal reliability and universal spare part availability.
Whether requiring specialized tank volumes (3,000L to 20,000L trailer units), unique spray bar extensions, or custom right-hand drive (RHD) configurations, our engineering team delivers bespoke drawings within 72 hours.
Real-time GPS tracking, remote heating diagnostic alerts, and automatic digital spray job reporting uploaded direct to client ERP platforms.
Automated surface roughness (IRI) scanning with AI dynamic application rate adjustment—applying more binder over micro-cracks automatically.
Zero-emission induction tank heating powered by onboard lithium energy storage units, reducing job site carbon footprint by 40%.
Fully autonomous driverless bitumen distributors operating in tandem with autonomous paving trains via V2X low-latency mesh communication.
