The register lists here 13 versions with unladen weights from 2,900 to 8,700 kg, gross vehicle weights from 18 to 48 t and widths from 2,550 to 2,600 mm; lengths are recorded for most versions from 5,000 to 15,550 mm.

With gross vehicle weights up to 48 t and lengths beyond 15 m, these semi-trailers sit in the heavy segment of long-haul freight, as Norwegian registration data shows for tipper, jumbo and platform semi-trailers. The naming by axle count and body form – plan for flatbed, dumperslep for tipper – follows a system common in Nordic vehicle registration.

When buying a used semi-trailer of this class, check the frame and side rails for cracks and corrosion, the function of the air suspension and brake system, wear on the axle assemblies and tyres, and the condition of the kingpin and fifth-wheel plate. On tippers, also check the seal and function of the hydraulic rams; on the jumbo and platform models, check the condition of the load areas and lashing points.
