With an unladen weight of 5,400 kg, that leaves a payload of 36,600 kg. The dimensions are 13,500 mm in length and 2,500 mm in width.
Fifth-wheel or drawbar load and the design of the coupling decide which tractor unit suits a trailer like this. At this weight class the trailer is built for long-haul or heavy and abnormal-load work, not for occasional private use.
On a viewing, the brake cylinders, lines and the air system's tightness are among the first points to check. The brake system and brake lines deserve particular attention, as this is an area often neglected in everyday use. With several axles, a test drive is a good chance to compare braking effect between axles. The suspension and any dampers should be checked for leaks and correct ride height. On the frame and at the drawbar mounting points it is worth checking for rust and old weld repairs. Wheel bearings and steering knuckles should be checked for play and uneven running noise. The coupling head or kingpin shows heavy wear where the trailer has seen intensive use.
