Onbekend AHW – trailers with no recorded make in the Dutch vehicle register: collective page of trailers (aanhangwagen), 5,700 to 18,000 kg gross vehicle weight
This page gathers trailers for which the Dutch vehicle register RDW records no make: "Onbekend" is Dutch for "unknown" and serves in the register as a placeholder entry when no manufacturer is entered – it is not a vehicle brand. The AHW suffix stands in the RDW register for "aanhangwagen", trailer in the general sense; the model designations listed here are registration type codes, not manufacturer data.

The register lists here 5 versions with unladen weights from 4,520 to 12,660 kg and gross vehicle weights from 5,700 to 18,000 kg. Lengths range from 7,760 to 12,330 mm and widths from 2,500 to 2,600 mm.
With gross weights up to 18 tonnes and lengths of over twelve metres, these are heavy low-loader or semi-trailer units for transporting construction machinery, bulk goods or general cargo, of the kind registered in Dutch haulage and construction. The combination of a high gross weight and a comparatively low unladen weight is typical of payload-optimised designs in this market segment.
On used examples of these heavy trailers, the condition of the chassis and axles, the function of the brake system and the overrun brake or air-brake system, the condition of the load bed, and corrosion on load-bearing parts all matter; since the manufacturer is unknown, an independent technical inspection before purchase is advisable.

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.
