Tanuki Posted November 8, 2014 Share Posted November 8, 2014 For the last decade-and-a-half, trailers have been subject to EU type-approval: as previously mentioned, see http://www.ntta.co.uk/ To be brutally honest, and having on several occasions over the last couple of decades having had to drag spectacularly-inadequately-engineered/maintained homebrew 'trailers' off the UK's roads, I can only say "About Time Too".

diggervan Posted November 8, 2014 Author Share Posted November 8, 2014 I can see your point about homebrew trailers but to be brutally honest it depends how and whose built it after all I for Williams and the like did not start to mass produce trailers on awhim it was one at time know dout in a shed Quote Link to comment Share on other sites More sharing options...
miketomcat Posted November 8, 2014 Share Posted November 8, 2014 I may be wrong but I think you can build your trailer then a form of iva test is needed so you need to build it to pass that. Mike Quote Link to comment Share on other sites More sharing options...
western Posted November 8, 2014 Share Posted November 8, 2014 Trailer IVA manual https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/367387/IVA-inspection-manual-for-categories-o1-o2-o3-and-o4-trailers.pdf Section O2 is what you need to use as guidelines to ensure a good result O1,Very Light Trailers, 0.75 Tonnes or less O2, Light Trailer, Over 0.75 Tonnes up to 3.5 Tonnes Quote Link to comment Share on other sites More sharing options...
miketomcat Posted November 9, 2014 Share Posted November 9, 2014 Thanks western I way sure I'd seen it when looking for car iva manuals. Mike Quote Link to comment Share on other sites More sharing options...
Blanco Posted November 9, 2014 Share Posted November 9, 2014 It is one of those things that you can do, and I have done it, but will it be worthwhile? If you need something truly 'bespoke' then maybe it will be. The key thing is that the key components need supporting paperwork for the iva/sva, that (usually) means using established industry standards (eg Knott, or Peak ) for at least the brakes and coupling and probably the axles. Drawbar you can do yourself more easily but you will need to supply calculations to show that it is within the strength parametres, but if you don't fancy it then even standard drawbars are available. There was a guy on a certain well known auction site advertising sub 500kg plant trailers for 3 ton diggers at around £2300 with the iva which I reckoned was a bargain, knowing how much admin is involved, never mind building the trailer! Here in France it is even worse as class O2 trailers have their own vehicle registration documents and vehicle insurance as well, all of which may come to the UK eventually.

diggervan Posted November 9, 2014 Author Share Posted November 9, 2014 Yes blanco all you have said is wot my mate was thinking all my axels /brakes/coupling/drawbar length etc conform to existing rules and regs but he seems to think it's all about to change to something like you have in France. Whitch might make mine not worth while depending on what they change. Thanks miketomcat/Western I will dibble check what I know with the link you surjested Bob Quote Link to comment Share on other sites More sharing options...
western Posted November 9, 2014 Share Posted November 9, 2014 any changes should be on the GOV.UK website. have a look through this lot too,https://www.gov.uk/search?q=trailers Quote Link to comment Share on other sites More sharing options...
Blanco Posted November 10, 2014 Share Posted November 10, 2014 Just to clarify, its not so much the standard of the components that is changing (Knott KFG35 hitch for example has been going for 20 years to my knowledge and will continue), but the fact that the components used and the structure of the trailer is demonstrated and documented to perform/conform to the legislation. Older components will be fine so long as you can get there respective test documentation and certificates of conformity to include in your file for the iva..

landrover598 Posted November 10, 2014 Share Posted November 10, 2014 Has anyone here actually put a very light trailer through IVA ? what's it like? I'm contemplating a building a small camping trailer from scratch. Quote Link to comment Share on other sites More sharing options...
Blanco Posted November 11, 2014 Share Posted November 11, 2014 I guess the answer is probably not, trailers of only 500kg, and up to 750kg (behind a Landy for example) tend to attract (rightly or wrongly) much less attention; on the plus side the file would be smaller, no brakes or brake actuation to consider.
