Trailer Highlights
Superior Thermal Efficiency with the 50KL 4-axle Bitumen Insulated Tank Semi-trailer
Transporting liquid asphalt demands rigorous temperature control and structural integrity. Our 50KL 4-axle Bitumen Insulated Tank Semi-trailer is specifically engineered for long-distance bitumen logistics, ensuring the cargo remains in a liquid state for immediate discharge upon arrival. This high-capacity tanker combines advanced heating technology with a reinforced 4-axle chassis to maximize payload without compromising safety.
Advanced Insulation and Heating Systems
The core advantage of this tanker lies in its multi-layer thermal protection. We utilize 100mm high-density rock wool insulation covered by a stainless steel jacket, minimizing heat loss even in extreme cold. According to Bitumen Transport Standards, maintaining a stable temperature is critical for road construction efficiency. Our integrated diesel burners and heating pipes provide consistent warmth, preventing bitumen solidification and reducing operational downtime.
Heavy-Duty 4-Axle Chassis Design
To handle the 50,000-liter capacity, the 50KL 4-axle Bitumen Insulated Tank Semi-trailer features a reinforced carbon steel frame. The 4-axle configuration provides superior weight distribution, ensuring compliance with strict road regulations while offering enhanced stability on uneven terrain. This design significantly reduces tire wear and extends the service life of the vehicle under heavy-load conditions.
Precision Engineering for Safe Operations
Safety is paramount when handling high-temperature bitumen. This trailer is equipped with explosion-proof manholes and specialized high-temperature-resistant discharge valves. The internal baffling system reduces liquid surge during transit, improving braking performance and overall vehicle control for the driver.
Boost your road construction efficiency today with a reliable transport solution. Our engineers can customize the tanker to your specific project needs. Contact our technical sales team for a professional quotation and detailed CAD drawings.

Product Overview

1. Efficient Rear Heating System
This highly efficient rear heating system guarantees constant temperature control for your liquid asphalt. It rapidly warms the cargo, completely eliminating solidification risks to ensure incredibly fast, smooth, and cost-effective unloading operations every single time.
2. Punched Anti-Slip Treads
Engineered for ultimate workplace safety, these durable punched anti-slip treads span the tank top. They provide maximum traction for operating personnel in harsh weather, drastically reducing slip hazards during critical loading, inspection, and maintenance procedures.
3. Rock Wool Insulation Layer
Lock in the heat with our premium rock wool insulation. Available in customizable thicknesses from 3cm to 10cm, this high-performance thermal barrier significantly prevents heat loss, saving valuable burner fuel and preserving optimal cargo viscosity.
4. Anti-Overflow Manhole Cover
Experience absolute peace of mind with our specialized anti-overflow coaming manhole cover. This precision-engineered safety feature guarantees zero leakage during turbulent transit, protecting the environment while ensuring ultimate safety for your valuable hot bitumen cargo.
5. Four-Axle Configuration
Maximize your hauling profitability. Our heavy-duty four-axle design drastically increases overall payload capacity and road stability. By evenly distributing massive weight, it significantly lowers tire wear, extending component lifespan and reducing your fleet's maintenance costs.
6. 6-Inch Internal Heating Pipe
Maximize thermal efficiency with our robust 6-inch internal heating pipe. Working seamlessly with the high-performance burner, it delivers rapid, uniform heat distribution throughout the tank, ensuring your heavy asphalt remains in the perfect fluid state.
7. 0.5mm Insulation Cladding
Protect your investment with robust 0.5mm thick insulation cladding. Available in color steel, aluminum alloy, or stainless steel, this durable exterior offers superior corrosion resistance and a sleek, professional appearance tailored to your corporate branding.
8. Stainless Steel Binding Strap
Secure your thermal efficiency permanently. These heavy-duty stainless steel binding straps lock the insulation layer tightly in place. Highly corrosion-resistant and incredibly long-lasting, they ensure structural integrity and prevent thermal bridging even under extreme vibrations.

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.
