The power of <span class="highlight">corrugations</span>

That load is fine, being poly pipe it is quite a light load.

Thanks in anticipation.
Which road is it?? going by the name on the door would say it's the GRR.

Admittedly 1 pipe would be light but a load like that would be reasonably heavy and the amount of harmonic flex over corrugations would increase the weight in the centre of the trailer I would have thought.

It was posted here some time ago that a toolbox on a vans rear bar could put up to 7 times its own weight on the bar when bouncing up and down on rough roads so presumably the same would apply here.
Perhaps a couple of extra straps to keep it stiffer MAY have helped.

Wouldnt like to have to ring the boss and tell him no matter what the cause LOL

All it needs is a set of training wheels!

check out another photo(on google earth) of same load at tilmouth roadhouse on the tanami road ..might be a bit too much whip in that load to have the trailer extended out so far me thinks..

Could you post a link to it please

Snoopy,
you just answered your own question, corrugations took their toll on the rig.

Now this is me overloading to the max.


Image Could Not Be Found

Yep but you have wheels under the load not half a k between them like the OP.

Anything is likely to buckle with that sort of a span.

If he had a dolly under it further back it may not have happened.

Apart from the corrugations it looks like an illadvised rig for the job in the conditions in which it was expected to work.

Snoopy, Graham or Tom,

Took 3 long loads up the cape that even Toots Holzimer said we would not make it, and I mean long. Well we did, through some very, very bad corrugations and dips.

Extendables are made to do exactly what is shown in the picture, just the corrugations took their toll.

Enough said.

Hi Rockape,

That load would be well over the 30 tonne mark easy. To me the trailer has been extended too far and it does not have the support in the middle. Yes the corrigations would take its toll on that. The forces applied to the middle of the load would be great ( as it has already shown). I suppose you could just put it down as a learning curve. To me it is a great picture but would not like to be in the drivers shoes when he had to ring the boss.

Cheers
Simon.

Sorry forgot to add....The trailer would not be overloaded.

Cheers
Simon.

Why is anyone surprised that it sagged? Place a length or a bundle of conduit between two supports, one at each end, in the shed and leave it for a couple of days. Depending on the ambient temperature it will sag and drop to the floor. And that is without any corrugations.

Cheers,

Jerry

Wilko,

yep !!!! but at least you can get the load off easily now. They might patent it as the new easy load banana trailer.

Hey Phil,
What sort of vehicle was it and at what speed were you driving?

My 1994 LandCruiser, towing a camper-trailer, experienced zero problems last winter on our trip up to Cape York, and with the same shocks that were on the car when we did the CSR many years earlier.

Just wondering ....................

A 100 series 4.2TD LC. It was faulty from the start. Just popped out. We were on the Starcke Track and doing about 40K when it happened. First time problem with the car. Got a temporary replacement up to Laura Roadhouse the next day. Even fitted it for me. I now carry spare shocks.

Not a problem since. And we have travelled that lovely road to the Bungles and Mitchell Falls. Mostly at 50. 80 plus on the better roads that are corrugated. The car seems to travel well at that speed. But we also drop the tyre pressure down a tad.

I would not swap shock absorber brand. I am happy with my choice. They are Bilstein. Very similar to the ones in my sons rally car. Excellent ride. Hardly built up any heat on the above roads. Just an unlucky break. When back home I called them and it was replaced immediately. I had to send them a photo though. Arrived by overnight parcel express the next morning and in the car before lunch.

Kingo,
I like the way you think.

Have a good one

Scotty,
good stuff, let us know what happened.

Hey mate
From the text i just got it happened about 2 years ago was a bran new trailer maiden voyage, it was not over loaded but police, insurance and company reports said it was stretched to far not glutted properly and bad bad corrugations. Not sure where it happened but feel for the driver if it was hot cause he would have been waiting a while to get it transfered to another trailer. Ill let ya know more when I get more info ha ha

Scott

Thanks for that Scott

Matthew,

I feel for you on those corrugations

Have an easier day today
