Was the trailer acvtually plated at 3500kg?

If i havent mi-understood and the trailer was only 2600kg then there probably wasn't much room for error.

.
1700kg boat + outboards + gear etc.....?

Does it have swing beams or have the roller carriers failed when the trailer gave way?

<edit> In the first pic it does appear to have swing beams, though it's not that clear. I'm also quite shocked that the recovery guy pulled something that much of a mess on a speclift with ratchet straps. It needed a flatbed.

Hey Nos4r2

Something SW Rib Charter mentioned sparked my curiosity....in post 20 he posted a pic of a failed weld on the rear swing beam carrier....

To me it does seem that it was a multi roller trailer but i suppose the real question is "what is it plated at?"

Your right about the recovery guy though, very brave considering many other welds had failed further down the length of the trailer

I'm sure it is....

There could be a number of reasons why the trailer failed, not properly hitched as Wilk said, incorectly loaded somehow, maybe the driver didnt see and slow down for a speed bump traffic calming measure (although why they call them "calming" is beyond me as they make my blood boil...especially when your towing something big )

Still, your picture shows that the trailer in question was plated at 3500kg.

The plate on the trailer (well actually on the detached drawbar!) says 3500kg GVW, 2850kg Capacity

I suspect not all of the failures shown were present 'til the recovery guy winched it all down to the spec lift.

It looks to be the same model as Randskis-the roller ramp model.

Are you missing a bolt or 2 from that pic? there no stop bolt in the sliding bar.

Hi Paul,
Yes indeed, the stop bolt is sat on the drawbar out of shot. Whenever I go away I remove the drawbar for a bit of added security. Thanks for the headsup

The design looks weak IMHO. It is a long stretch from the axles to the towball. Most of the trailer length it has dual rails, which would imply that it would not be strong enough to have just singles. As you get towards the drawbar the dual rails finish and it goes down to a single rail, which does not appear to be beefed up other than an additional piece of box section down the middle, that wont contribute much to the up and down flexing that is going to occur at the point where the dual rails finish. Personally I believe the dual rail should have continued right to the front where the tow ball coupling is attached. Problem is , it would make if more labour intensive to fabricate and push the price up.
I am also not a fan of using extruded materials in this situation. It all depends what the quality of the extrusion mix is.

This damage would suggest that the unfortunate driver may have hit something with the trailer which caused catastrophic damage to the trailer. Even a speed bump at high speed? Was there any damage to the Tyres or wheels?
