Ifor Williams – other trailers: the collective page of Welsh utility trailers outside the named ranges, from BV (beavertail) and CT (cattle trailer) to HB (horse box) and GX/GD/GP (flatbed), 470 kg to 2.12 t kerb weight
Ifor Williams Trailers was founded by Ifor Williams in Cynwyd near Corwen in Wales and still builds its trailers there for agriculture, horse keeping, construction and leisure. The model codes match their purpose: BV marks the beavertail platform with a lowering load bed for plant machinery, CT the cattle trailer, HB the horse box, GD, GP and GX the general flatbed and dropside trailers in rising payload steps, DP the tipping trailers for groundwork and landscaping; the following number gives the approximate payload in hundreds of kilograms.

The register lists 99 versions here with kerb weights from 470 to 2,122 kg, gross weights from 1,500 to 3,600 kg, lengths from 3,790 to 7,420 mm and widths from 1,730 to 2,500 mm.
Ifor Williams is among the largest British trailer makers and market leader in the UK and Ireland for cattle and horse trailers; galvanised chassis and extensive direct sales through its own plants and dealers shape the brand's reputation.
On used trailers, what counts is the condition of the galvanising and chassis welds, the floor and side panels on cattle and horse trailers, the overrun brake coupling and its linkage, tyres and wheel bearings, and on tipping trailers the hydraulics; spare parts are readily available through the dense Ifor Williams dealer network.

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.
