New chip box

[Rupe]

My new chip box is comign along well but getting heavy!! We need to weigh it and then decide what material to use for the roof.

 

So far its made out 1.5mm zyntec steel sheets, with folded ends and stiffeners. Theres no frame just the sheet. An outer layer will be added usign foamex board or grp panels ready for signwritting.

 

The struts at the top are just holdign it together for now!

Looks good!!

rupe, are you taking orders

rupe, are you taking orders

 

Can do!

 

This one is custom built for my truck but could look at making a standard size one that just bolts straight on to any truck bed.

 

Wait for the final pics, it will look quite different, but if it gets too heavy then it may end up as a log shed!!

Looking great Rupe, steel though, damn heavy,or is it? especially for a LDV, mine struggles with a full load and the chipper, was aluminum too expensive?

 

I can't remember what your tool box is made of, steel also?

 

I have seen tarp used for roofing, looks good if custom made but will you need to stand on the roof? I expect so.

I went through loads of materials weights and measures.

 

You can pull the square foot weight for most materials off the internet and suprisingly, aluminium wasn't lighter than 14mm glassonite or if I recall steel frame and sheet

[Rupe]

Hopefully this is lighter than frame and sheet in steel as there is no frame.

 

Aluminium is three times more expensive and not as strong. A doble skinned alu box might do it like many arb trucks but the plan is to have one strong skin (steel) and an outer skin which is light and not structural.

 

The tool box that is going on the new truck is aluminium.

 

My tipper bed is aluminium also and the dropsides are 40kgs each. They are being removed. One sheet of this steel is approx 40kgs and we have used three and a bit so far.

 

I will need to stand on the roof but it could be aluminium which steel strenghteners. Still not sure about this yet.

This is handy for weights.

The roof on my ply chip box was really thin ply, i think 6mm. It worked because i bent it up in an arch, and then used struts to tie the two sides of the chip box together. I bet you could do the same in steel and it would be very strong and fairly lightweight.

Cool site.

 

It says my sheets are 35kg each, not bad! The aim is to keep it under 200kgs that way the whole tipper and chip box will weigh less than a factory fitted steel tipper.

 

A steel roof may put it over the edge plus it would be best to not have too much weight high up, centre of gravity and all that, but the roof must still be strong enough for ladders etc.

 

Aluminium is a third lighter so a 3mm chequer plate roof should be a bit lighter than 1.5mm steel.
