Korthaus: a long EU class O4 trailer with an 11,700 kg gross weight, a 14.25 m overall length and a wide 7.90 m axle spread
With a gross weight of 11,700 kg, this trailer sits just above the 10-tonne threshold and so belongs to EU trailer class O4, rather than to one of the lighter classes below it. At 14.25 m long, however, it is unusually long for its gross weight: it carries comparatively little mass over a very long area rather than a lot of mass over a short span.

At a kerb weight of 5,200 kg, the payload works out to 6,500 kg, a little more than the trailer's own weight. The four wheels are spread across two axles with a 7.90 m span, more than half the overall length – the two axles sit far apart, which at this length helps keep deflection even along the long frame. The width is 2.50 m.
This combination of great length, moderate weight and widely spaced axles is typical of trailers carrying long but light goods, such as building components, pipes, masts or similarly bulky material. Class O4 requires compressed-air brakes regardless of the relatively moderate load.
When buying used at this length, the frame itself matters most: deflection over the 14.25 m span should be checked both unloaded and under load, as should the two widely separated axle mounts for rust and cracking. The air-brake lines running the full length and the lighting on the overhangs should also be checked carefully before any purchase decision.

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.
