Repeated failures of mudguard bracket

Hi Folks (sorry it's a dull one)

Wonder if you can help out. I have a 5 month old trailer that has had 4 instances of the mudguard brackets failing. The failure looks to be metal fatigue caused by the weight of the guard wobbling as I drive. It's failed twice on a motorway and I've been forced to tie it up from the hard shoulder - not a good experience

See the photo attached.

Does anyone have any recommendations for brackets / solutions to stop this happening. I've been told that this isn't happening to any other owners of this trailer type, just me...

The manufacturer suggested I'd been standing on the guard - ffs i'm 6ft 3 and don't need a lift up.

Cheers
Chunk

they only look like 10" plastic mudguards though?... maybe it's the pic, combined with dodgy eyes!

It looks like a manufacturer that I recognise. They used to do a mudguard step, that bolted on to where that L-bracket now sits. It may be worth asking if they have any in stock, as they're a much more substantial bit of kit.

Are you standing on it to get into the boat?

Thanks TrailorGuy, will call and ask.
Not standing on it, I'm big enough to leap on without touching it (also the tubes overhang so not sure that would possible). The tubes don't touch it when launching, recovering or towing. From what I can tell it can only be either inclusions in the metal, fatigue or a combo of both.
Cheers

TrailerGuy - as you said, when I took the mudguards off they were pretty light plastic. For all you budding metallurgists just been out to remove the brackets. Happy to hear your thoughts - see the photos below.
Will send one off to be checked for inclusions and the other back to the manufacturer and see if they'll help out with replacements.
Cheers

Probably cheap quality mild steel it's just torn apart near the bend which is a weakness.
I would pop down to a fabricator and get some new ones knocked up a bit thicker

Mick, I'd agree. Just annoying to have spent £2k on a trailer less than 5 months ago and then for the dealer and the manufacturer to imply that its my fault...

...Not best pleased

Weld them back together and put a small triangular gusset in the 90 degree angle. Problem solved.

If the manufacturer is that full of crap (and I agree with you, they shouldn't have failed) I wouldn't be going back to him!

I would be giving them some grief and try and get some money back
I have made hundreds of brackets like that in my blacksmithing days
To me its the cheap shite they are made from

Quit hitting stuff!

The thickness of the bracket is probably okay, if they had another piece or two of metal tying the angle together. It is the "beer can effect" as shown by the ragged edges. They wobble with the wind resistance probably more than the weight. Try to hold the flap in your hand out the window at speed and you will quickly see what I mean.

Nos, going to get some made up today, thanks for the pointer re: the triangular gusset. I'll call the manufacturer - to be fair to them it is the dealer who has relayed the comments to me 2nd hand. I haven't spoken to them directly yet.

Quick update, spoke with the manufacturer and they were very happy to help. No questions or quibbles and already had a resolution for the problem.

I know you're sorted now but....

I've often noticed vibrating mudguards as I pass by trailers on the motorway or watching them on B-roads so the last trailer I made myself (well I fitted everything to a bare spine) I used galvanised angle about 35mmx35mmx4mm. It was "self-bracing" and I could see in the mirror is was nice and rigid even at motorway speeds.

Thanks for all the responses folks.

Just to finish off with an example of good service. I bought the trailer as a package with a new RIB earlier in the year, the UK distributor has been in touch to say he'll swap out the trailer for a new custom one from a different manufacturer. Excellent support and service - big thankyou for the offer.

EDIT: Just to confirm I'm not slating the quality of the current trailer, its good, just had poor brackets fitted originally which when broken makes it illegal to tow...

Repeated failures of mudguard bracket

We had the same problem at work with cheapo mudguard brackets snapping exactly in the same way all within a few months of each other , in the end we finished up making our own from some thick walled steel tubing/pipe never had any trouble after that & no one was standing on them it was just the road/ wind vibration that caused it .
