Obermaier – other models: the collective page of trailers outside the named ranges, OS, OD and TF types, 0.68 to 9.1 t unladen weight, up to 28 t gross weight

This page gathers the Obermaier trailers the register could not assign to a named range. The type designations follow a letter-and-number pattern: OS and OD mark the axle count (single or twin-axle) and the body shape, TF types carry additional codes for side height and equipment, and the attached number gives the build size or payload class.

The register lists here 30 versions with unladen weights from 675 to 9,120 kg, gross weights from 2,000 to 28,000 kg, lengths from 4,500 to 11,250 mm and widths from 2,050 to 2,600 mm.

The span from light trailers around a tonne gross weight to versions of 28 tonnes shows a range running from the simple agricultural or trade transport trailer to the multi-axle heavy trailer, as used for machinery, building materials or bulky goods. The different body shapes – from the open platform to the closed box with a higher side – reflect equally different loads, from general cargo through bulk goods to machinery and equipment.

On the light models, the axle, brakes and sides count; on the heavy versions, additionally the frame and connection points for distortion and cracking, the brake system given the high gross weights, and tyres and lighting; on the larger models, wear and play in the drawbar and trailer coupling also count. Spare parts run through the regional trailer trade.

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.
