Unsinn UDK

The register lists here 7 versions with kerb weights from 579 to 980 kg at a gross weight of 3,500 kg, lengths from 4,497 to 5,705.5 mm and widths from 1,815 to 2,220 mm.

With a gross weight of 3,500 kg these trailers also fall into EU class O2 and require their own service brake; the low kerb weight against the gross weight allows for payload of close to 3 tonnes. Such trailers are used in commercial transport, agriculture and private use, competing with a wide range of other German trailer builders in the same weight segment.

On a used trailer of this size, what counts is the condition of the overrun device and brake linings, corrosion on the frame, drawbar and axle mounts, the function of the lighting and connector, the condition of the side panels and load floor, and tyre age and rim condition; a current inspection report and a traceable service history are especially helpful given such a varied range. Spare parts for axles, the overrun device and lighting are widely available through the general trailer-accessory trade.
