I wanna / will be building my own tandem 8 x 5 box trailer (2 tonne capacity), not for bush use.

I have/had a couple of questions;

No. 1. was the drawbar length, but research in the archives answered that question.

No. 2. is positioning of the axle/s, are they placed centrally or set back to the rear and if so what is this measurement?

Thanks

Why not call a trailer place, pretend your shopping for one, adn ask them all the specs ;) Ive done this before on things.

FWIW, my 7x4 single axle has 6ft draw bar.

No wonder they say "buyers are liars"

When salespeople supposedly tell lies they are lambasted all over this & other forums .... yet it seems perfectly OK for buyers to lie!

But, why pretend .... why not be honest & just ask for advice, most business people are helpful & not as seems suggested many times on this forum, just there to rip people off!

I myself have tried being "Honest" with some companies... If your not buying most dont wanna waste their time with you.

EG one company that makes rear bars with wheel carriers.

Its easier most times to just play them, you will get more information out of 99% of them this way over saying,

"hi, I have no interest in buying your insanely overpriced item, which I want to have a mate make for about 1/5th the price of yours.. Would you be ever so kind as to let me measure it up and take him the plans, with 200 odd photos from every angle"...

G'day Rod,
Axle position would depend on what you intend to be carrying, & how the load will be distributed... You'll notice that horse floats generally have their axles set back closer to the rear....
Many, many years ago, I built a few (8x5 tandem) box trailers for different people, the one that I still have in my backyard I made in 1984.. (It still does the job of collectin' the "farwood" each winter)....
The trailers that I built all had the axles located centrally, with the weight of the A-frame providing sufficient ball load when empty... then it's up to the user how it's loaded to maintain balance... IMO, ball weight on a tandem trailer is less critical than it is with a single axle, but you still want *some* weight on the ball.... YMMV ...

Regards, Ed. C.

Thanks Ed. C.

Info on the site I have listed above has the axle placing as a ratio of 60% / 40%. With 60% to the front.

Thanks for that Nick.

I've checked them out, they have a Vehicle Standards Bulletin National Code of Practice Building Small Trailers. It dosen't address the axle position/s specifics... well not by what I can read anyway.

Maybe U need to check what you are putting under it. My local spring supplier tells me that its hard to get the old 45mm wide springs & fittings and that they break easier than the 60mm which also have thicker leaves & fewer of them.

8x5 won't follow the same tracking as your fourby but if it's not for off road use them that won't matter anyways. Just thought I'd offer the point anyway
cheers
