Soz, thought this is what you were after.

I like the look of those. Do they extend?

I think some of you are missing the point. There will be no compression of the springs at all, only extension.
No Pete I think you are missing the point 😂😂😂😂 an extension spring will give too much movement before it tightens whereas a compression spring mounted correctly will be firmer but still allow the articulation you need but also provide a dead stop if something drastic happens eg wheels end up above your head. I would take a picture of our sprayer but it’s not here at minute but if you have a plate mounted to chassis then another plate mounted to box with say a 15 mm gap then a bolt through them both with a compression spring on the bolt also and big washer to hold spring in tension. So the ideal would be box sitting on one of your mounting balls in centre with the compression spring holding it down there job sorted. (As will I has pictured should explain it better either one each side or 1 bigger one in centre holding box down onto the ball)

Most likely me!!!! It can sometimes take a while for the penny to drop!!

The first thing we did when my brother came round for a head scratching session was to run one front wheel up a heap of stone. That showed us the twist in the chassis and the point of doing so was that it seems to work the opposite to how you would think.
 
Yes too easy to extend a spring is where I am getting at but ball in centre and compression spring holding it job sorted


I see that , but the ball joint in the centre won’t work because 1, there is no room and 2, I have just spent the thick end of £2000 having the body shotblast and powder coated so there is no way we are drilling, grinding or welding it!!!!

I am using the existing Bredal fixing points, which are near the front and one either side. They lend themselves to being fixed to the side of the chassis.

I see your point entirely now that whilst extension springs will work in good going, it will take something different to work in the event of a slight disaster!!! The example above will give better lateral retention, I see that now.

Like I said a few posts ago, I’m not short of enthusiasm, just talent!!!

You do underestimate your self! Just sometimes it takes a minute for things to become clear!

You’d do well to spend an hour looking around a gritter lorry. Same concept no?
Yes, but they dont do off road the flexing of the lorry chassis is quite significant if it is like a unimog, The leaf sprung suspension has great load carrying capacity but the chassis needs freedom to flex independently,As he is operating no where near the chassis limits i suspect it will be OK however it is done

If the rear axle had more articulation would the chassis need to flex as much ? . I know it would involve loads of work but a trailing rod , panard rod and air bag set up could be fitted and incorporate a self levelling rear end .

There are some good discussions on various Expedition vehicle prep forums regarding mounting bodies 3 4 Point etc... Zetros Daf MAN & all sorts of other stuff.. But they're not carrying the weight like this will but they'll obviously get some serious flex with the terrain they'll encounter.

The 4 Point setup looks better in my eyes... Single Central bushed mount front and rear and fixed in the centre both sides of the rails.

I'm probably waffling others will know no more, maybe. (y)
 
The truck chassis isn't exactly built to flex but built to a minimum weight usually whichever body type is fitted will actually add extra strength and stiffness. Seen as you don't want to alter the spreader now painted might you have to build a subframe to mount it on?
