Otto Treyler Semi-Trailer – EU class O4 semi-trailer with a 35,500 kg gross weight, 13,540 mm length and 9,700 mm wheelbase
With a gross weight of 35,500 kg, this Otto Treyler semi-trailer falls into EU class O4, the heavy trailers and semi-trailers above 10 tonnes. A semi-trailer rests its kingpin on the tractor's fifth wheel, carrying a substantial share of its load through the towing vehicle rather than on axles of its own at the front.

At 13,540 mm long and 2,550 mm wide, the trailer has an unladen weight of 10,600 kg, giving a payload of around 24,900 kg. Six wheels on a 9,700 mm wheelbase spread this load across a multi-axle group at the rear, while the permitted top speed of 90 km/h is lower than the figure usually seen on trailers.
Class O4 requires an air brake system, and towing a semi-trailer of this size requires driving licence category CE. The combination of great length, high payload and a limited top speed is typical of classic long-haul and freight-forwarding use, where a tractor unit works with changing semi-trailers.
When buying used, check the kingpin and fifth-wheel plate for wear, inspect the air system and lines for leaks, and check the axles and brakes of the rear axle group for even wear. The chassis around the trailer plate should also be examined for cracks and deformation, since this is where the greatest forces act, and the landing legs used to support the trailer when uncoupled deserve a look as well.

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.
