The register lists an unladen weight of 25,000 kg for this vehicle. Length is 13.49 m, wheelbase 8.79 m, and width 2.55 m, at the maximum width allowed for road vehicles. Such a high unladen weight is not unusual on reinforced low-loaders built for extremely heavy single loads, whose frame alone already accounts for much of the rated gross weight.
Class O4 trailers run on compressed-air brakes. With such a massively built structure of its own, the design focus lies on a torsion-resistant, highly load-rated frame rather than maximum remaining payload, so that even heavy loads applied at concentrated points are carried safely.
When buying used, distortion and cracking on the reinforced frame deserve particular attention, as does the condition of the air suspension along the full length and the tightness of the air lines. At the fifth-wheel coupling, check for wear at the kingpin, and on the axles, look for even tyre wear as a sign of sound axle geometry. The condition of the mudguards and the lashing points along the frame is worth a look as well, since both take steady wear in daily use.

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.
