With an unladen weight of 9,000 kg, that leaves a payload of 41,000 kg. The dimensions are 13,300 mm in length and 2,550 mm in width. The wheelbase is 9,700 mm. The trailer runs on 12 wheels. The design top speed is given as 85 km/h.
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. 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. Paperwork and the validity of the roadworthiness test belong to every viewing.

What to check before buying
- Search the frame and welds at the axle mounts — that is where cracks start.
- Check the brakes and the last inspection in the papers.
- Work the gross weight against the towing vehicle before buying.
- Compare the chassis number with the papers.
- Look at the floor, cover or body from the inside — rust does not show from outside.
