With an unladen weight of 5,540 kg, the payload comes to 14,460 kg, more than double its own weight. At 10.66 m long, 2.44 m wide and with an 8.87 m wheelbase, the trailer sits on a long chassis whose axles are spread across almost the full length of the frame, a design that spreads the gross weight over a large chassis area.
Category O4 trailers are generally fitted with an air brake system acting through multi-axle brake distribution. Towing in a combination requires licence category C1E or CE in the EU, depending on the combination's gross weight. The long frame with widely spaced axles suits bulky loads spread over the full length.
When buying a used trailer from the 1953 build year, the frame along its full length matters most: check rust, cracks and earlier repair points especially thoroughly on such an old vehicle. The checklist should also cover the air brake system including its lines and brake cylinders, the axle bearings for play, and the function of the lighting and electrical connector. Given its age, it is also worth checking the availability of spare parts for the brakes and axle.

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.
