Wijnveen – other models: the collective page of heavy-duty trailers outside the named ranges, types with gross weights up to 43,000 kg, unladen weights 1,668 to 9,620 kg, lengths up to 13,350 mm

This page gathers the Wijnveen trailers the register could not assign to a named range. Type designations such as OA-13-30-SB25036, OA-12-10-SB23, OA-13-28-SB30 and KOBS 18000/3 are multi-part model codes for heavy-duty trailers, supplemented by the entry 24-10.000. All 14 entries thus carry technical codes rather than their own model names.

The register lists here 14 versions with unladen weights from 1,668 to 9,620 kg, gross weights from 10,000 to 43,000 kg, lengths from 3,140 to 13,350 mm and widths from 2,470 to 2,580 mm.

With gross weights of 10 to 43 tonnes and lengths of over 13 metres, these trailers count among the heaviest versions in the register, of the kind used to transport construction machinery, bulk material or farm produce behind suitably rated tow vehicles. Trailers of this size typically sit in the commercial fleet of construction, agricultural-machinery or recycling firms and are less often owned privately.

On a used purchase, frame and welds for cracks and rust count on these heavy-duty trailers, axles and brake system for wear matching the high payload, hydraulic tipping functions where fitted, and the overrun brake actuator or tow eye; parts for axles and brakes run through the general commercial-trailer trade. On tipping versions, the tightness of the side panels and the function of the locks on the rear and side flaps 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.
