The register lists here 6 versions with unladen weights from 4,620 to 6,500 kg, gross weights from 18,000 to 40,500 kg, lengths from 8,100 to 10,900 mm and widths from 2,500 to 2,550 mm.

Trailers of this class belong to category O4 and are used in the transport of building materials, bulk goods and machinery; the stepped sequence of weight classes lets hauliers match the trailer to the tractor unit and the permitted combination weight instead of always running the heaviest version. Such trailers usually run as tandem or tridem versions with steered trailing axles, which improves manoeuvrability on tight site access roads.

On used examples of these trailers, frame and welds, the condition of axles, suspension and brakes, tyre tread and the tightness of the sides count; spare parts for axles and brakes run through the usual axle makers, body parts more through the manufacturer itself. At the periodic inspection, brake linings and the condition of the steering axles are common points of attention on this trailer class, so the inspection history is worth checking.
