The register lists here 27 versions with unladen weights from 420 to 12,220 kg and gross weights from 1,300 to 39,000 kg. Lengths range from 8,830 to 13,940 mm, widths from 1,800 to 2,600 mm.

The span thus runs from light class O2 trailers to heavy class O4 trailers above 10 tonnes gross weight – a mixed line-up such as many European trailer builders run in parallel for trade, construction and transport, from the car-trailer class to the low-loader. Such a wide spectrum from light to extremely heavy versions under one brand name is not unusual among smaller trailer builders who build one-off jobs for customers alongside series production.

On used trailers, the condition of the drawbar, overrun brake and side panels and rust on the frame count on the lighter models; on the heavy versions, axles, brake system, frame cracks and the condition of ramps and hydraulics, plus the inspection sticker and load-securing points. Spares for such a small-scale brand are usually only obtainable from the trailer builder itself or independent workshops. Comparing the chassis number with the vehicle papers is also important, since conversions and special builds occur more often in such widely spread ranges.
