Forss Parat.P23-TI-90 – an EU class O4 trailer with a 37,000 kg gross weight, 8,400 kg kerb weight, 9,140 mm length and 2,580 mm width
The Forss Parat.P23-TI-90 belongs to EU trailer class O4, covering all trailers and semi-trailers with a gross vehicle weight above 10,000 kg. This class requires compressed-air brakes, fed from the towing vehicle's brake system, which safely slow the trailer in long-distance haulage behind suitably approved towing vehicles.

At a gross weight of 37,000 kg and a kerb weight of 8,400 kg, the trailer carries a payload of about 28,600 kg, more than three times its own weight. At 9,140 mm long and 2,580 mm wide, the trailer is built for heavy loads despite its comparatively compact dimensions.
Such a high ratio of payload to kerb weight on a comparatively short platform points to a trailer for dense, heavy goods such as round timber, stone or bulk material, where weight rather than volume defines the load. Trailers like this need a correspondingly robust chassis and axle design able to carry the high axle load permanently.
When buying used, the chassis around the axle mounts deserves particular attention, since fatigue cracks and corrosion appear there first given the high payload share. The compressed-air brake system, with its lines and coupling heads, should be checked for leaks, as should the wheel bearings, and the load platform itself for wear from heavy, sharp-edged cargo. A look at the towing eye and its pin is worthwhile as well, since it takes the full pulling load of a heavily laden trailer.

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.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
