Raf – other models: the collective page of trailers outside the named RA and R.A. ranges, 640 to 15,540 kg kerb weight, up to 33 t gross vehicle weight

This page gathers Raf trailers outside the named ranges. The type designations combine the abbreviation RA or R.A. with a four- or five-digit number and varying letter suffixes such as K, KD, PD, SD or TD. Model names range from short codes such as RA30 to elaborate codes such as RO-ST-15-18 or R0-SD-12-18-MA.

The register lists here 56 versions with kerb weights from 640 to 15,540 kg and gross vehicle weights from 3,200 to 33,000 kg, at lengths from 3,280 to 13,900 mm and widths from 1,500 to 2,740 mm.

The weight range from just over three to 33 tonnes gross vehicle weight spans a single-axle agricultural trailer through to a multi-axle heavy trailer for construction and transport use. Heavy versions of this size are used in earthmoving, material transport on construction sites and heavy agricultural haulage, where they compete with trailers from other European makers in the same weight range.

When buying used, check the frame and axles for rust and cracks, the function of the tipping ram and hydraulics on the larger versions, the brake and overrun system, and the condition of the side boards. On the largest versions also check the condition of twin tyres, the underrun guard and the towing coupling, plus a valid inspection sticker; spares for axles and brakes mostly come through standard suppliers.

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.
