The frame adopts either a straight or goose-neck structure. The space frame, formed by welding the longitudinal beams and the integral penetrating beams, ensures the strength, rigidity, and toughness of the frame. This results in strong bearing capacity and prevents permanent deformation. The longitudinal beams are welded using fully automated submerged arc welding.
The new suspension system is characterized by high strength and strong impact resistance. The load is balanced across each axle, and the reasonable design of the system’s tie rod angle reduces the friction slip distance between the tire and the ground during frequent turbulence. This effectively reduces tire wear. Additionally, the adjustable tie rod and wheelbase can be modified to prevent the phenomenon of uneven tire wear and premature tire damage.
Advanced software optimizes the product's design to ensure a stable, reliable, and reasonable structure with a beautiful appearance, meeting the individual needs of customers.

Main Features:
Lightweight:
The use of aluminum alloy, stainless steel, or carbon steel materials makes the semi-trailer lightweight and provides a lower center of gravity.
Closed Loading and Unloading System:
This system concentrates the oil and gas discharged from the fuel tank trailer during loading and unloading, recovering up to 50%. Since oil and gas emissions are major contributors to urban haze pollution, the closed loading and unloading system helps recover gasoline and oil, reducing both pollution and waste. It has become an essential measure as prescribed by the state.
System Security
The vehicle’s security system continuously monitors its running state. If the system detects a loss of control, it will apply braking force to specific wheels to help the vehicle safely stay on track, preventing loss of control or rollover.
This vehicle is also referred to by several names, including fuel tank semi-trailer, fuel semi-trailer, 42,000-litre fuel tanker semi-trailer, oil tanker trailer, petrol tank trailer, 45,000-litre fuel tanker trailer, 3-axle fuel tank trailer, oil transport semi-trailer, fuel tank semitrailer, 50,000-litre oil tanker semi-trailer, tri-axle fuel tanker truck trailer, 4-axle fuel tank trailer, and more.

Advanced Process:
Design Drawing: Before production, we will send the design drawing to our customer for confirmation of the vehicle details. We aim to provide the most suitable product to our customer.
Cutting and Welding: The I-beam cutting is done using a Computer Numerical Control (CNC) Plasma Cutting Machine. The I-beam welding is performed with a Gantry Main Sill Welding Machine.
Tank Body Welding: We use European arc butt welding, round head, mechanical folding, and one-time forming technology.
Surface Treatment: To remove rust from the trailer body, we use sandblasting to treat the surface. This process ensures a beautiful appearance, with even coating, strong adhesion, and durable gloss.
Painting: One layer of anti-rust paint is applied, followed by two layers of topcoat.
Testing: We will test the trailer's quality before delivery.
