The register lists 16 versions here with kerb weights from 320 to 1,224 kg and gross vehicle weights from 1,400 to 3,500 kg. Lengths run from 3,820 to 6,686 mm, widths from 810 to 2,300 mm.
Class O2 trailers of this size cover the broad field between horse and livestock transport, enclosed cargo transport and machinery transport, and are towed behind vans and larger cars. The HB range is a widespread livestock and multi-purpose trailer in the British and European agricultural and leisure market, while the CT box trailers cover enclosed transport where the load must stay dry and secured from view.
When buying used, check the condition of the overrun brake and brake linings, play in the axles and suspension, tyre condition including the spare wheel, and corrosion on the chassis, floor panel and sides. On the HB livestock trailers, also check the rubber mats and partitions; on the enclosed CT types, the seal of roof and doors; and the completeness of the registration documents.
