Omavalmiste – self-built heavy trailers over 10 t (class O4) from the Finnish vehicle register: owner-built semi-trailers, mobile concrete batching plants, crushers, drying drums and sauna wagons, 11.6 to 72 t gross, 4.7 to 26 m long, up to 4 m wide
Omavalmiste means “self-made” in Finnish and is the entry of the registration authority Traficom for vehicles without a factory manufacturer. In class O4 – trailers over 10 t gross weight – it stands not for hobby building but for the special-vehicle building of businesses: semi-trailers and turntable trailers that hauliers, timber merchants and farm-machinery workshops built themselves, and the mobile plants of the construction industry registered on a trailer chassis. The model names show it: Betoniasema is a mobile concrete batching plant, Asfaltti-System an asphalt plant, Jälkimurskain a secondary crusher, Kuivausrumpu a drying drum, Saunamaja a sauna wagon; alongside stand axle counts (2-AKS, 4AKS for kaksi- and neljäakselinen), dimensions such as 13.9M and company names of bodybuilders.

The register lists 71 versions with kerb weights up to 72,000 kg, gross weights from 11,600 to 72,000 kg, lengths from 4,700 to 26,084 mm and widths from 2,200 to 4,000 mm.
These vehicles express the Finnish practice of registering heavy special trailers after individual inspection – for timber transport with combinations up to 76 t gross, for building sites that need a concrete plant only for weeks, and for road builders who move their crushers by truck.
Anyone taking over such a vehicle checks registration, inspection deadlines and special permits for widths over 2.6 m, frame and welds, axles, suspension and braking system (EBS/ABS), kingpin or drawbar eye, lighting and tyres; parts come from axle and brake suppliers such as BPW, SAF and Wabco.

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.
