Trailer Highlights
Specialized 40KL 3-axle Bitumen Insulated Tank with Heating System
The 40KL 3-axle Bitumen Insulated Tank with Heating System is engineered specifically for the long-distance transportation of liquid asphalt and coal tar. This heavy-duty trailer utilizes a high-strength carbon steel tank shell integrated with a premium rock wool insulation layer to maintain optimal cargo temperature. According to Asphalt Institute standards, maintaining consistent heat is critical for material integrity, and our system ensures a temperature loss of less than 1°C per hour.
Advanced Thermal Retention and Efficiency
Equipped with a dual-diesel burner heating system and large-diameter heating tubes, this 40KL 3-axle Bitumen Insulated Tank with Heating System significantly reduces pre-discharge waiting times. The 100mm thick high-density insulation layer is protected by a sleek stainless steel or aluminum outer cladding, providing both aesthetic appeal and corrosion resistance in harsh environments.
Robust Mechanical Configuration
Built on a reinforced chassis, the 3-axle configuration features world-class brands like BPW or FUWA to ensure maximum load stability. The integration of high-quality pneumatic valves and a dedicated bitumen pump system allows for rapid loading and unloading, effectively lowering operational costs and increasing site efficiency.
Every 40KL 3-axle Bitumen Insulated Tank with Heating System undergoes rigorous pressure testing and thermal leakage inspections before leaving our facility. Whether you are operating in remote road construction sites or urban infrastructure projects, this trailer delivers the durability required for 24/7 operations.

Our Advantages
Robust Suspension for Harsh Road Conditions
Designed specifically for the challenging road conditions often found in Africa, Southeast Asia, and South America, our trailer chassis is reinforced with heavy-duty mechanical suspension and widened leaf springs. Customers can also opt for air suspension systems for sensitive cargo. Paired with 12R22.5 or 315/80R22.5 wear-resistant tires, the trailer maintains excellent stability, reduces tire wear, and extends the overall lifespan of the vehicle even when navigating unpaved or mountainous roads.
Shipping and Delivery Solutions
We provide cost-effective and secure shipping solutions for global buyers. For a standard trailer, we typically recommend RORO (Roll-on/Roll-off) ships or bulk cargo ships. To provide the highest level of protection, we thoroughly spray the entire exterior with a protective wax coating and securely cover the vehicle with heavy-duty tarpaulins before it leaves the factory. This double-layered protection prevents seawater rust and weather damage during the voyage, ensuring the trailer arrives at your port in pristine condition.
Reliable After-Sales Support and Spare Parts
As a direct manufacturer, we don’t just sell trailers; we build long-term business partnerships. Every trailer comes with a comprehensive one-year warranty covering the main chassis and tank body. We understand that vehicle downtime costs you money, which is why we maintain a complete inventory of OEM spare parts, including API valves, brake pads, and suspension components. Our dedicated technical support team is always available to provide maintenance guidance and remote troubleshooting, ensuring your fleet remains safely on the road.
