Kar Lehtonen KAR-4-36: EU class O4 trailer with a gross weight of 36,000 kg, a length of 10.60 m and a payload of about 27,600 kg
With a gross weight of 36,000 kg, the KAR-4-36 is among the heavy vehicles of EU trailer class O4. Vehicles of this size are used in heavy-haulage operations, where high payload per trip over long distances is the priority.

With an unladen weight of 8,400 kg, the trailer carries a payload of around 27,600 kg, more than three times its own weight. The body is 10.60 m long and 2.55 m wide. This ratio of unladen weight to payload is typical of a design optimised for payload rather than its own weight.
Class O4 trailers carry air brakes as standard and need a towing vehicle with a matching air supply and load-dependent brake force control. Driving a combination like this requires licence category CE, since the permissible gross train weight clearly exceeds the limits of categories BE and C1E. 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 trailer like this, it is worth checking the frame for rust perforation and old welds, and the brake system with its lines and couplings for leaks. The wheel bearings and suspension should be checked for play, as should 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.
