Trailer

I would piece chassis would be the way to go as it would be more reliable than trusting the weld or fixings of the two parts.

With the Material how would you repair an aluminium one in the middle of nowhere?
with steel you can at least rig up a bush welder and carry on.
The steel may be heavier but IMO is more likely to withstand the riggers of offroad travel.

Just my thoughts

concur with previous reply (Kev) ..except cant see a problem with a two piece...sometimes helps as the A frame welded under the main box frame may give more ground clearance subject to how the hitch assembly is mounted......

the rest of the trailer frame is welded elsewhere and so if you are worried about strength of welded joints then who is to say what area of the assembly will break first..the A frame on the box frame or somewhere on the box?

As for aluminium absloutely forget it 110 %....steel is the only way to go....Some years ago in Rudall River NP I broke both the main leaf springs on the trailer just behind the hangers (the other end was a slipper)...and the axle assembly parted company behind the trailer ...great feeling I can tell you just before dark .....we came form the Gunbarrell up the Gary and onto the Tallawana from Windy Corner and the corrugutions on the Gunbarrell probably started it and the rest of the journey finished it..

First thing was to make a good camp and jack it all up level and safe.....2nd settle in with a stubbie and camp fire and worry about it in the morning look at it refreshed and unhurried early next morning in a much better frame of mind

I bush welded it back together together with clamps I carried just in case and completed our holiday....those welds came all the way home some 2,500 km's......springs or trailer chassis you can always weld it somehow...aluminium and you can expect to leave it behind to join the already too much junk out there now

Hi On The Rocks
just wondering if you meet a steel chassis with aluminium body ???

wayne

Hi again
And thx for the reply's so far and to wayne yes sorry forgot to say that it would be a steel chassis with alloy top

as to the two piece all in one chassie and braw bar 95% of all the ones I looked at have been with a welded draw bar witch is welded back to the spring hanger can any one tell me are they strong or the other one piece is it the only way to go feeling very confused about that as I say most are welded not one piece?????

thx again

I am not surprised that you have not seen many one peice chassis as i looked about five years ago for a box trailer manufacturer around my area and had no luck. In the end I made my own and paid for the box sections to be press bent and had some checkerplate folded up. The trailer came up so well that I decided to have it Gal dipped and fitted some hilux leaves and electric brake axle. This trailer had to be a bullet proof, do every thing trailer at the time,from collecting sawn logs to dirt bikes to topsoil, for moving house,to carrying the holiday stuff ie. Tinny and outboard etc etc. Have now bitten the bullet so to speak and cut half the box and mudgaurds/sidesteps off and am in the process of building a camper with lots of easily accesable storage space. And naturally, for saving weight so it's practical, it is being made from aluminium.

Don't give up .... just take your time!
