Jyki 3-AKS – Finnish trailers from Jyväskylä: three-axle versions, 6.8 to 7.7 t unladen weight, 28 to 30 t gross weight, lengths up to 12.55 m
Jyki of Jyväskylä in Finland builds trailers. This page covers the 3-AKS range, whose designation "aks" comes from the Finnish akselinen (axled) and marks the version as a three-axle trailer, with the variants 3-AKS, 3-AKS/340+182, 3-AKS/432+136, 3AKS and 3AKS 1T. As a trailer with its own drawbar, the vehicle runs on its own axles at both ends behind the towing vehicle and, unlike a semi-trailer, does not put a vertical load on the tow hitch.

The register lists here 5 versions with unladen weights from 6,800 to 7,700 kg, gross weights from 28,000 to 30,000 kg, lengths from 7,150 to 12,550 mm and widths from 2,450 to 2,500 mm.
With gross weights up to 30 tonnes, the 3-AKS counts among the heavier three-axle trailers of Finnish freight transport used by hauliers behind trucks for general cargo, timber and other loads; the length span from 7.15 to 12.55 metres shows short and long variants of the same axle configuration. Three-axle trailers of this kind are common in Finnish freight transport because of the long haul distances and axle-load regulations.
On a used trailer, check for rust on the frame and drawbar, the condition of the three axles, brakes and tyres, and the operation of the lighting and brake connections; spare parts for this Finnish brand usually run through specialist commercial-vehicle workshops. Tyre tread depth and age, and the condition of the jockey wheel and safety chain, also belong in a pre-purchase check.

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.
