This 4 axle oil tank semi-trailer is a mid-to-large capacity liquid transport vehicle tailored for commercial petroleum logistics and bulk oil distribution services. Optimized for medium and long-distance highway transportation, it is perfectly suited for delivering diesel, gasoline, kerosene and other refined petroleum products for gas station supply, energy companies and cross-border freight fleets. The 4-axle structural layout achieves scientific load dispersion, effectively complying with international axle load restrictions while offering larger single-trip shipment volume compared with conventional 3-axle tank trailers.

The entire tank body is fabricated from premium high-strength carbon steel or lightweight aluminum alloy, adopting integral one-time spinning molding and full penetration welding technology. Every weld joint undergoes strict air tightness and pressure resistance testing to eliminate oil leakage, evaporation loss and safety hazards during high-speed driving. Built-in multi-group anti-wave baffles effectively buffer liquid turbulence and inertial impact, lowering the vehicle’s center of gravity and greatly improving driving stability and anti-rollover performance on curved and uneven road sections.

The trailer supports customizable independent compartment design, allowing classified storage and separate loading/unloading of different oil products in one transportation cycle, which effectively boosts operational flexibility and reduces logistics costs. It is fully equipped with explosion-proof manhole covers, emergency cut-off valves, static elimination devices and automatic pressure relief systems, fully meeting international dangerous goods transportation safety standards.

Equipped with four heavy-duty standardized axles, high-stability suspension system and sensitive full-air brake system, the trailer delivers reliable load-bearing capacity and stable braking performance under full-load 45000L working conditions. Matched with standard landing gear, anti-collision protection devices and full set of high-brightness safety warning lights, it complies with global road traffic regulations. Featuring large capacity, high safety coefficient and long service lifespan, this 4 axle 45000L oil tank semi trailer is a cost-effective and high-efficiency transport solution for professional energy logistics enterprises.
