High quality 3 axle 40000L fuel tank trailer for sale
40,000 litre three axle fuel tanker in Q345 steel with 5% vapour space
This three-axle fuel tank trailer is a professional device specially designed for efficient and safe long-distance liquid transportation. It is widely used in the batch distribution of fuel such as petroleum, diesel, and gasoline. Its overall external dimensions are 11,500mm in length, 2,500mm in width, and 3,950mm in height. The structure is compact and complies with international road transport standards. The position of the towing pin is 500mm away from the front end of the front baffle. It can be flexibly adjusted according to different towing vehicle specifications to ensure towing stability. The three-axis spacing adopts an optimized layout of 6,000mm+1,310mm+1,310mm, combined with the design where the outriggers are located 2,500mm behind the traction pins. This not only ensures a balanced weight distribution during driving but also enhances the convenience of loading and unloading operations. The total capacity of the tank reaches 40,000 liters, and an additional 5% steam space is reserved to cope with temperature changes.

Problems It Solves
Thermal expansion has nowhere to go
40,000 L capacity plus 5% vapour space, so temperature changes do not pressurise a full tank.
Corrosion and coating failure
SA2.5 shot blasting with a polyurethane topcoat to a total dry film thickness of at least 80 μm.
What You Get For the Money
40,000 kg payload at 8,000 kg tare
11,500 × 2,500 × 3,950 mm with a G.V.W.R. of about 48,000 kg.
Tested and certified build
Hydrostatic test to 5 psi (35 kPa) on each compartment, with welding by qualified welders to the applicable national standard.
Safety equipment fitted
500 mm carbon steel safety manhole with breather valve, two 8 kg dry powder extinguishers, anti-slip walkway and steel mudguards.
Technical Description
Technical Construction
The main body is made of high-strength Q345 steel, with an end plate thickness of 6mm, a shell thickness of 5mm, and a wave-proof plate thickness of 4mm. The structural strength is ensured through precise welding processes. It is simultaneously equipped with JOST 2-inch bolt-type traction pins, 10 standard mechanical suspensions of 13mm×90mm, and 3 square axles of 150×150mm for 13-ton class, with an effective total load capacity (G.V.W.R.) of 48,000kg, of which the self-weight is approximately 8,000kg and the net load is 40,000kg. Achieve a balance between lightweight and high load capacity.
Build and Finish
The tank of this vehicle has passed the 5psi (35Kpa) water pressure test. Its surface has been treated with SA2.5 grade shot blasting and coated with polyurethane topcoat, with a total dry film thickness of no less than 80μm, and it has excellent anti-corrosion performance. The braking system adopts dual-pipeline pneumatic braking, equipped with T30/30 spring brake chambers, WABCO emergency relay valves, and 50L dual air tanks, ensuring rapid and reliable braking response. The unloading system integrates a 3-inch ball valve, a 6-meter-long rubber hose, and a 4-inch pneumatic bottom valve, which is easy to operate and has strong sealing performance. The safety configuration includes a 500mm diameter carbon steel safety manhole with a breathing valve, two 8kg dry powder fire extinguishers, anti-slip walkways, and steel mudguards, comprehensively reducing transportation risks.
