With an unladen weight of 11,390 kg, that leaves a payload of 24,610 kg. The dimensions are 13,860 mm in length and 2,550 mm in width. The wheelbase is 8,920 mm.
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. 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. 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.

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.
