With an unladen weight of 2,350 kg, that leaves a payload of 3,150 kg. The dimensions are 8,250 mm in length and 2,550 mm in width. The wheelbase is 5,100 mm.
Fifth-wheel or drawbar load and the design of the coupling decide which tractor unit suits a trailer like this. That places the trailer, in commercial use, between light car trailers and heavy semi-trailers.
On a viewing, the brake cylinders, lines and the air system's tightness are among the first points to check. 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. Lighting, wiring harness and plug connectors are common weak points on older trailers. Tyres and rims should be checked for age and even wear, especially if the trailer has stood unused for a while. On bodies with tarpaulins or side boards, the condition often only shows up on close inspection for leaks and deformation.
