Liquid Natural Gas LNG Tanker Three axles Semi-trailer China Factory Direct Sale
52.6cbm LNG tanker with an S30408 stainless tank, aluminium alloy main beam and 6 tonne curb weight.
Overview
What This Trailer Is Built For
A three-axle LNG tanker with a 52.6 cubic metre S30408 stainless tank at 0.68MPa design pressure, on an aluminium alloy main beam that brings the curb weight down to 6 tonnes. That is a significant saving on a cryogenic trailer, where the vacuum insulation itself is heavy and the chassis usually eats into payload. The end plate is 6mm in 30408 or Q345R, braking is dual line pneumatic, the kingpin is an interchangeable 2 or 3.5 inch, landing gear is a 28 tonne two-speed manual unit, and suspension is leaf spring or air bag. A vapour recovery system is available as a customer option and the finish can be original aluminium or painted.
Key Benefits
What You Get
- Aluminium alloy main beam holds curb weight at 6 tonnes, which is exceptional for a cryogenic trailer
- 52.6 cubic metre volume at 0.68MPa design pressure covers standard LNG distribution loads
- S30408 stainless tank body is the material specified for cryogenic service
- Interchangeable 2 or 3.5 inch kingpin lets the trailer work behind different tractors
- Vapour recovery available as an option where boil-off must be captured
Problems Solved
What It Fixes
- Cryogenic insulation is heavy and leaves too little payload on a steel chassis
- Fixed kingpin sizes limit which tractors can pull the trailer
- Boil-off vapour is lost or vented where no recovery system is fitted
- Carbon steel tanks are unsuitable for cryogenic temperature
Who It Is For
Operators Who Buy This Model

Comparison
How It Compares
| Compared With | How This Model Differs |
|---|---|
| Steel-chassis LNG tanker | The aluminium alloy main beam saves several tonnes of tare, which is payload on every trip; steel costs less to buy and repair. |
| LPG pressure tanker | LNG requires cryogenic insulation at -160 degrees and below; LPG is carried under pressure at ambient temperature in a much simpler vessel. |
| Smaller cryogenic vessel | 52.6cbm is a full commercial load; smaller vessels suit local distribution with tighter access. |
Use Guide
Operating This Trailer
- Complete the cold-down procedure before the first fill
- Confirm the kingpin size setting matches the tractor fifth wheel
- Monitor tank pressure against the 0.68MPa design figure
- Operate vapour recovery, where fitted, at every transfer
- Use cryogenic protective equipment at all connection points

FAQ
Questions About This Model
What Is the Tank Volume and Pressure
52.6 cubic metres at 0.68MPa design pressure, with a welded joint coefficient of 1.
Why Is the Curb Weight Only 6 Tonnes
The main beam is aluminium alloy rather than steel. On a cryogenic trailer, where the insulated vessel is inherently heavy, that saving goes straight to payload.
What Is the Tank Made Of
S30408 stainless for the tank body, with a 6mm end plate in 30408 or Q345R.
Can It Work Behind Different Tractors
Yes. The kingpin is an interchangeable type in 2 or 3.5 inch, so the trailer is not locked to one fifth wheel size.
Is Vapour Recovery Available
Yes, as a customer option. It is worth specifying where boil-off must be captured rather than vented.
Leaf Spring or Air Bag Suspension
Both are available. Air bag gives a gentler ride for the vessel on paved roads; leaf spring is simpler to repair.
Does It Come Painted
You can have it in original aluminium finish or painted to your requirement.
