The suffixes KI and KTI mark further equipment steps of the same AB base type.

The register lists 13 versions here with unladen weights from 360 to 2,020 kg, gross weights from 1,150 to 3,500 kg, lengths from 4,890 to 8,720 mm and widths from 2,150 to 2,550 mm.

With gross weights up to 3.5 t, the Ostmann trailers sit in the class towable on an ordinary car licence; the span from small single-axle units to models over 8.7 m long points to a broad range of transport and special-purpose trailers for agriculture and trades. Trailers like these are typically used by farms, landscaping and building businesses, and tradespeople for transporting material and equipment.

When buying used in this class, what matters most is the condition of the drawbar eye and overrun brake assembly, corrosion on the frame and load bed, the function of the braking system, and the wheel bearings and tyres. Spare parts for trailers of this size are usually stocked by the established trailer dealers. The jockey wheel, sideboard hinges and the condition of the floor boards should also be checked.

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.
