The Self-build Ferraari AT3500 is a trailer (Self-build) (EU vehicle class O3), registered as built in 2021. It is 6,530 mm long and 2,320 mm wide, weighs 900 kg unladen and has a permitted gross weight of 3,650 kg.
The Self-build Ferraari AT3500 offers a payload of 2,750 kg – the gap between unladen and permitted gross weight. More than half of the gross weight is therefore available for cargo.
With a permitted gross weight of 3,650 kg the trailer exceeds the BE limit of 3,500 kg. It requires a C1E licence as long as the combination stays within 12,000 kg, otherwise CE – in practice behind a truck or an agricultural tractor.
Among the 348 trailers (Self-build) with a stated length, the Self-build Ferraari AT3500 at 6,530 mm is in the middle of the range (rank 216); the range runs from 3,000 to 26,084 mm. The Finnish vehicle register lists one unit – one of the brand's most common models.
Omavalmiste – further self-built utility trailers from the Finnish vehicle register: generator sets, screening plants, crushers, conveyor belts, cable wagons, site containers and workshop wagons on trailer chassis
Omavalmiste is Finnish for “self-made” – the entry that the registration authority Traficom keeps in the manufacturer field when a trailer does not come from a factory but was built by a business or keeper and registered after a registration inspection. This collective page covers the utility trailers outside the class division, and the model names show what Finnish businesses put on wheels: Aggregaatti is the mobile generator set, Seulontalaitos the screening plant, Keskipakomurskain the impact crusher, Hihnakuljetin and Hiekankuljetin conveyor belts for gravel and sand, Syöttösiilo and Fillerisiilo silos, Kaapelikärry the cable wagon of the grid operators, Korjaamovaunu the workshop wagon, Työmaakoppi, Työmaaparakki and Sosiaalitilavaunu the site accommodation units, Sauna the sauna wagon. Alongside stand the axle counts (1-AKS. for single-axle), dimensions such as 185X668 and brands of the chassis and units used – Atlas Copco, Lokomo, Valmet, BPW, SAF.

The register lists 48 versions with kerb weights from 220 to 26,000 kg, gross weights from 700 to 10,000 kg, lengths from 3,000 to 22,000 mm and widths from 1,820 to 3,500 mm.
These vehicles are the mobile infrastructure of Finland's construction, gravel and energy industries: plants that stand on a site for weeks and are moved by truck or tractor instead of being permanently installed – registered as trailers after individual inspection.
Anyone taking over such a vehicle checks registration and inspection deadlines, frame and welds, axles and braking system, drawbar eye or ball coupling, lighting and tyres, on generator sets and plants their service history; running-gear parts usually come from BPW, SAF or Knott.

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.
