Karbonsan 3 Axle Semi Trailer: three-axle EU class O4 semi-trailer with a gross weight of 38,500 kg, a length of 11.16 m and a 90 km/h speed limit
With a gross weight of 38,500 kg and its designation as a three-axle semi-trailer, this vehicle falls into EU trailer class O4. As a semi-trailer, it rests its kingpin on the tractor's fifth wheel instead of carrying a steered front axle or drawbar of its own, and is typically used in long-haul transport.

With an unladen weight of 9,250 kg, the semi-trailer carries a payload of around 29,250 kg. The body is 11.16 m long and 2.55 m wide, runs on three axles with six wheels in total, and has a distance of 7,950 mm between the fifth-wheel coupling and the axle group. Unlike most trailers, this vehicle is limited to 90 km/h.
Class O4 semi-trailers carry air brakes as standard, linked through the fifth-wheel coupling to the tractor's brake system. Driving a combination like this requires licence category CE, and the tractor must have a fifth wheel rated for this gross weight. Trailers in this weight class also need rear underrun protection under UN/ECE Regulation R58, intended to reduce the severity of collisions where a car runs into the back of the trailer.
When buying a used three-axle semi-trailer, it is worth checking the kingpin and fifth-wheel plate for wear, and all three axles and wheel bearings for even wear. Also worth checking are the brake system with its lines, the frame for rust perforation, and whether the chassis number matches the registration papers. The rear underrun protection should additionally be checked for secure mounting and any deformation.

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.
