Ii-Trailer Other models

The register lists here 68 versions with unladen weights from 130 to 750 kg, lengths from 2,500 to 5,950 mm and widths from 1,620 to 2,400 mm.

O1-class small trailers are widespread in northern Europe, where they are used for garden and builders'-merchant runs, boats and small machinery, and are popular with private customers because no further licence is required; lengths of nearly six metres show that narrow, elongated designs such as boat or ladder trailers are also built within this weight class.

On a used example, corrosion on the frame, the condition of the wheel bearings (on unbraked trailers often the only moving component), the floor sheets or boards, the coupling head and safety chain, the age and condition of the tyres, and the lighting system with its plug count; spare parts for small trailer brands are often only available to a limited extent.
