Happy Trailer ORTT: six versions of the class O4 heavy-duty range, unladen weight 6.76 to 8.76 t, gross vehicle weight up to 44 t, lengths 10.8 to 13.9 m at a constant 2.55 m width
The ORTT range from Happy Trailer covers multi-axle trailers in class O4, meaning a gross vehicle weight above ten tonnes. The versions listed in the register, from ORTT 22/110 to ORTT 44/327, show the spread of the range from lighter to the heaviest variants, with correspondingly higher unladen weight, greater payload and increasing length.

The register lists 6 versions with unladen weights from 6,760 to 8,760 kg, gross vehicle weights from 25,000 to 44,000 kg, lengths from 10.80 to 13.90 m and a constant width of 2.55 m.
Trailers in this weight class serve heavy-haulage and construction traffic and the transport of bulky, especially heavy goods, where a semi-trailer combination alone reaches its payload limit and a drawbar trailer with its own axle load raises the combination's permitted payload. Registering such trailers requires a towing vehicle with sufficient permitted drawbar load and compliance with the rules for combinations with a total train weight above 40 tonnes.
When buying used, what counts in this trailer class is the condition of axles and brakes, frame cracks from sustained load, the function of the overrun brake or air brake system, and corrosion on load-bearing chassis members; a current inspection report and the availability of wear parts such as brake pads and suspension components should be checked before purchase.

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.
