How much is too much weight on rear of 130 tray

[pc3]

Folks I have a 2.2metre tray on my dual cab 130.....now I know your not meant to have too much weight on the part of the tray that hangs past the chassis. The first 700mm is taken up with dog cages, not serious weight. The next part will be a 600mm metal box where I keep food ammo grog etc. On trips, fair bit of weight here. My question is is either a spare wheel or 70 litres of water under rear most part of the tray too much for the chassis given the steel box is already past the rear wheels..... I also have an under tray 130 litre aux diesel tank that's 2 thirds past rear wheels as well. Just don't want to have chassis cracking issues due to the weight and cantelliver effect if the coil springs.

Just pack on the weight till it breaks and then back off a few kg's ! :lol2:

Vlad is spot on - as usual. Follow this advice to the letter. As you're loading her up to breaking point, consider max payload, taking consideration for where the weight will be placed in the tub and the conditions you will carry that load over. Obviously, there will be different stresses imposed by driving a track that will bring in articulation, compared to smooth tar driving. ;)

Hi,

In addition to this, you are also permitted to go until the front wheels lift off the ground, then back off a kg or two. Its one of those "whichever comes first" situations.

Take a picture when you get to either point though, or it never happened! :twisted:

Spoke with arb today they said 60 litres of water held at rear most part Of my 2.2m tray won't be an issue.So I have ordered a 60 litre poly rv tank.

Gah. I just wrote a long detailed semi physics calculation filled reply, and just lost it all.

In short, it said, 70kg of water + a spare tyre should be fine, long range tank assumed to be between the chassis rails. If you loaded up the very rear edge of the tray only, about 700kg would result in the same force as 1200kg over the axle. The cantilever effect would be worst in the middle of the chassis, but what you are proposing should not represent a significant cantilever force. But obviously, do try keep the weight as far forward on the tray as possible.

Seano.

This may help with calculations...

Thanks folks well I am going to try and get the wheel and water under the tray, what it means with my set up is that the wheel would need to be on one side and water the other side. Water tank is 815mm long tyre 780mm, I'm 8cm short width ways with the tyre wondering if I deflate the tyre a little will it squash in ?
Thanks for help and advice thus far

Oh forgot to add my 130 litre auxiliary diesel tank sits above the ome tank. It's attached to the underside of the tray.

Hi,
I'm not sure how much the Dual Cab impinges on the space available where I put my spare tyre (mine is a D130 cab chassis) but I mounted mine under the tray, forward of the rear LH wheel, and there is more info here (http://www.aulro.com/afvb/90-110-130-defender-county/85421-trying-get-my-head-round-things.html)

Same as what Velt said. But if you add another axle????
