With an unladen weight of 3,080 kg, payload comes to 16,920 kg, a high share of the gross weight typical of a lightly built chassis with an open load platform. At 8.00 m long, 2.55 m wide and with a 4.40 m wheelbase, the trailer sits on a compact, two-axle chassis that carries the high payload on a short base rather than spreading it over a long frame.
From class O3 upwards, trailers of this size are generally fitted with air brakes rather than the simple overrun brake used on light trailers. Towing it as a combination requires driving licence category C1E or CE in the EU, depending on the combined train weight. The short build combined with a high payload calls for even load distribution across the platform, since axle loads on a short two-axle chassis rise quickly if cargo is bunched at one end.
When buying a used unit, check the frame and load platform closely: deformed main rails from point overloads and corrosion on the cross members and ramp mounts are common weak spots on short, heavily loaded chassis. Check the air lines and reservoir for leaks, listen to the axle bearings for play, inspect the load-lashing points for deformation, and check the ramp hinges and locking pins for wear.
