▶ Chassis System:
• The vehicle utilizes a HOWO NX heavy-duty chassis, equipped with an H77L R day cab (with a small rear sleeping/storage space).
• It is powered by a Weichai WP12S400E201 Euro II engine with a rated power of 400 HP (294 kW).
• The transmission is an HW19710 manual gearbox.
• Tire specification: 12.00R20.
▶ Bitumen Tank:
The bitumen tank has a capacity of 18,000 liters and features a composite structure consisting of a carbon steel inner shell, a rock wool insulation layer, and a stainless steel outer cladding, offering excellent thermal insulation.
The tank structure is robust with an optimized center of gravity, making it well-suited for heavy-duty transport. It is also equipped with heating pipelines to prevent the bitumen inside from cooling and solidifying.
▶ Bitumen Pump:
Equipped with a QGB950 bitumen pump, it offers a flow rate of up to 950 L/min and an operating pressure of 0.8 MPa. The pump is designed for various high-temperature bitumen media, featuring excellent wear resistance and robust sealing.
▶ Hydraulic System:
The hydraulic system is powered by a gear oil pump driven by the chassis power take-off (PTO). Serving as the power hub for the superstructure, it delivers stable pressure to drive the asphalt pump and the various actuating components of the spraying mechanism.
The asphalt pump is driven by a hydraulic motor.
▶ Gasoline Generator:
Equipped with a LUTIAN Machinery gasoline generator—featuring a rated power of 7.0 kW and a maximum power of 7.5 kW, with support for 230 V / 400 V, 50 Hz output—which serves as the power source for the thermal oil pump and the burner.
▶ Thermal Oil Heating System:
This system utilizes an indirect thermal oil heating method and is equipped with an Italian-made Riello G20 oil burner. It features automatic temperature control, with a heating rate of up to 12°C/h.
The thermal oil pump serves as the core of the circulation system, driving the high-temperature thermal oil in a continuous, closed-loop circuit between the heating jacket and the heat exchanger. This ensures that the heat generated by the burner is distributed evenly to the jacket of the asphalt tank, providing gentle heating to the asphalt stored within.
Designed for high-temperature resistance, the pump ensures stable, long-term circulation of the thermal medium with a consistent flow rate. This guarantees uniform heating throughout the entire tank, eliminates localized overheating, and effectively prevents asphalt aging or coking.
The system includes integrated temperature sensing and closed-loop control, allowing for the precise setting and maintenance of the required operating temperature. It is compatible with various construction materials, including hot asphalt, modified asphalt, and emulsified asphalt.
▶ Piping System:
Comprises an asphalt pump, filters, valves, spray pipelines, and nozzle assemblies (including pneumatic cylinder-actuated nozzles).
By configuring the valves in various combinations, the flow direction of liquid asphalt within the piping system can be controlled. Key functions include: self-priming/loading of asphalt, rear-mounted spray bar application, handheld spray lance application, circulation, suction-back (clearing lines), and system cleaning.
▶ Spraying System:
The spraying system is equipped with 36 nozzles, providing a maximum spray width of 6,000 mm. The application rate is adjustable within a range of 0.25–2.5 L/m², with a control precision of ±1%.
The recommended operating speed is 3–10 km/h, suitable for various applications such as prime coats, tack coats, and seal coats.
Each nozzle delivers material uniformly; the spray width and application rate can be flexibly adjusted to meet specific construction requirements, ensuring an even finish on the road surface and minimizing material waste.
▶ Operation:
The cab is equipped with an operation panel used to set and display the thermal oil temperature, asphalt temperature, and asphalt pump speed. It also provides controls for the thermal oil pump, asphalt pump, and burner, as well as functions for spraying, pumping in/out, individual nozzle control, and system cleaning.
▶ Applications:
• New Road Construction: Used for applying prime coats to base layers and tack coats between asphalt layers, enhancing interlayer bonding strength and ensuring the overall structural stability of the pavement.
• Pavement Maintenance (Seal Coating): Suitable for applying asphalt prior to slurry sealing or chip sealing; provides preventive maintenance for aging pavements, helping to delay cracking and water-related damage.
• Rural and Mining Road Maintenance: Leveraging the vehicle’s high off-road mobility and an independent onboard generator, it can perform spraying operations in remote areas, mining sites, or rural roads that lack a reliable power supply.
• Airport and Port Pavement Projects: Capable of applying emulsified or hot asphalt for paving projects in industrial facilities, airport aprons, and storage yards, meeting the requirements for large-scale surfacing work.
• Emergency Road Repair: Facilitates rapid asphalt application during the repair of flood-damaged or otherwise compromised roads, shortening repair timelines and quickly restoring traffic flow.
We CS TRUCKS also supply spare parts (original, OEM, and replacement) for all types of HOWO special trucks and trailers with discount and high quality to ensure our customer's trucks and trailers being in good working conditions.
