ISOKARMO – EU class O4 three-axle heavy trailer with a 40,000 kg gross weight, a 9,110 mm wheelbase and a 30,460 kg payload
With a gross weight of 40,000 kg, the ISOKARMO is among the heaviest trailers in EU class O4, well above that class's ten-tonne threshold. Trailers in this weight bracket come with air brakes as standard and run exclusively behind suitably approved tractor units in commercial heavy haulage.

At a kerb weight of 9,540 kg, the payload comes to 30,460 kg, more than three-quarters of the gross weight. The body length of 13,830 mm and width of 2,550 mm, with six wheels on a 9,110 mm wheelbase, shows a long, three-axle build typical of bulky, stable-shaped freight over greater lengths.
Driving such a combination requires at least a category CE licence, and the air brake system must work with all three axles together. The long wheelbase combined with the third axle spreads the high payload over a larger contact area and reduces the load on each individual axle compared with a two-axle trailer carrying the same payload.
When buying used, with three axles it is worth comparing tyre wear across all six wheels, since one axle with a different wear pattern can point to incorrect brake adjustment. The air brake system, with all its cylinders and lines, belongs on a test rig, and the frame along its nearly 14-metre length deserves a visual check for cracks in the welds at the axle mounts, front to rear.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
