Sinotruk Chassis
• Basic Platform: Based on the HOWO TX-W 8x4 350hp cab chassis, featuring a three-stage wheelbase design of 1800mm, 3800mm, and 1350mm.
• Powertrain: Equipped with a SINOTRUK MC07H.35-60 engine (350hp) and an HW13709XSTC2 9-speed transmission, it offers smooth power delivery and strong heavy-load climbing capability.

Intelligent upper body system
1. 18cbm large-capacity tank
• Stainless steel construction with double-layer insulation, supports storage of both emulsified asphalt (room temperature) and hot asphalt (160-190°C). A roof overflow prevention device and side access provide safe and easy maintenance.
2. Fully intelligent spraying system
• RY40-25-160 air-cooled hot oil pump: 10 m³/h flow rate, 28-meter head, 2900 rpm, 22 kW power, fast and stable material supply. The air-cooled design is suitable for high-temperature environments and increases lifespan by 30%.

• 36 stainless steel nozzles: 6-meter wide coverage, adjustable spray rate from 0.2-3 kg/m² with a ±1% tolerance. Supports "one-control-one" independent opening and closing, creating various spray patterns such as rectangular and trapezoidal.
• German Siemens Intelligent Control: Operated via a touchscreen in the cab, it allows real-time adjustment of the spraying function, nozzle spray rate adjustment, spray position movement, high and low speed switches, power take-off pump inlet and outlet switches, and background alarms.

3. Efficient Heating and Insulation
o Imported diesel burner: Calorific value 10×10⁴kcal/h, dual-circuit thermal oil heating system, temperature control accuracy ±2°C, heating rate ≥15°C/h, and an intelligent temperature control module that automatically sets the optimal operating temperature based on asphalt type.
4. Hydraulic System
The asphalt pump uses a QGB950 type, a proportional valve (Taiwan EFBG-03-160-HF), an automatic reversing valve, and a relief valve. The asphalt pump hydraulic drive motor is model 05-110-BD31. The hydraulic pump is a CBQ550-L or a GPC4-50R with rear engine power take-off. The radiator is a Risheng brand.

5. Humanized design:
• High-pressure cleaning device: Quickly rinses the tank after application to reduce residue.
• Electronic level gauge: Real-time monitoring of asphalt remaining to avoid running with an empty tank.
• Tool box and non-slip ladder: Convenient storage of spare parts and maintenance.
