The register lists here 16 versions with unladen weights from 410 to 10,960 kg and gross weights from 1,300 to 42,000 kg. Lengths range from 7,130 to 14,000 mm, widths from 1,700 to 2,550 mm.

The span runs from light class O2 trailers to heavy class O4 trailers above 10 tonnes gross weight; such mixed line-ups of small and very heavy versions are common among trailer builders who build one-off jobs alongside standard products. 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 drawbar, overrun brake and rust on the frame count on the light models; on the heavy versions, axles, brake system, welds and the condition of ramps or crane and hydraulic equipment. Spares for such a small-scale brand are usually only obtainable directly from the maker or through independent trailer 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.
