The register lists here 4 versions with unladen weights from 13,000 to 23,840 kg, gross weights from 13,000 to 30,000 kg, lengths from 11,850 to 14,270 mm and widths from 2,550 to 2,700 mm.

With unladen weights from 13 tonnes and gross weights of up to 30 tonnes, all versions belong to the heavy trailer class for special and construction-machinery transport, towed behind powerful trucks or run as independent centre-axle trailers on building sites and in industrial use. Widths of up to 2.7 metres run slightly over the standard 2.55-metre measure usual on public roads.

On a used example, axle and brake system condition, rust on the frame and load-bearing parts, the function of air suspension or leaf springs, and tyre and rim condition all count. Parts for trailers of this weight class typically come through independent commercial-vehicle workshops rather than a narrow manufacturer network. On the wider versions, checking frame reinforcements and fitted components also belongs on the pre-drive list. A look at the towing eye, lighting connectors and any signs of overload on the chassis rounds off the check.
