Over a total length of 11,810 mm, the 9,900 mm wheelbase takes up nearly the whole length, so the axles sit far out towards the ends of the chassis. Against an unladen weight of 9,750 kg this leaves a payload of 26,250 kg, at a width of 2,550 mm within the European standard measure. That leaves roughly 73 per cent of the gross weight rating available as payload.
A wheelbase spread this wide carries the axle load across the full length of the chassis and is typical of platform or low-loader trailers built for long, heavy goods such as prefabricated parts, pipes or machinery. Running it calls for licence category CE on the towing vehicle. The tyres and wheels fitted must be rated for the approved top speed and the registered axle load. Registration also depends on a valid approval certificate matching exactly the values stated here.
Buying one used, this wheelbase makes the centre of the chassis worth checking for sagging, since the greatest load falls there between the widely spaced axles, along with the condition of the brake lines over the full length, corrosion at the axle mounts, and whether the tyres' load rating matches the registered axle load. A complete inspection and service record makes judging the trailer's condition considerably easier.
