Ifor Williams Trailers car trailers up to 3.5 t (class O2) – Britain's largest maker since 1958, in-house galvanising: BV, CT, DP, 236 versions

Ifor Williams Trailers was founded in 1958 by farmer Ifor Williams in Cynwyd, Denbighshire, Wales, and with over 500,000 trailers built and around 800 employees across six sites is the UK's largest maker of trailers under 3,500 kg; an in-house galvanising plant still secures the quality and corrosion protection of its chassis. This class O2 collective page gathers the wide Ifor Williams range, from the BV series for general use through the CT and DP types to livestock and horse trailers; the letter codes by manufacturer logic denote the respective series, and the number after them the size or payload class.

The register lists 236 versions with kerb weights from 307 to 1,750 kg, gross weights from 800 to 3,500 kg and widths from 1,400 to 2,520 mm; lengths are recorded for 47 models and range from 2,930 to 7,080 mm.

Ifor Williams is the dominant UK brand for agricultural, livestock and general-purpose trailers, competing with Brian James Trailers, which is more strongly geared to vehicle and plant transport; in-house galvanising is regarded as a distinguishing feature against many rivals.

Thanks to full galvanising, frame corrosion is a less common problem on Ifor Williams chassis than on painted trailers, though welds and axle mounts should still be checked; in addition, check the coupling head and overrun brake, axles and rubber-torsion suspension, the lighting system, the condition of the floor and tarpaulin or bodywork, and tyre age; spares are supplied through a dense dealer network across the UK and continental Europe.

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.
