HI
I am at present fastening my tank down in the van with cargo straps and using the supplied hooks on the floor of the van. I really would like to use something a bit safer like a cage or something. What do you use? where can I get a cage?

 i use the heavy duty straps safe up to 2000 kg for my 650 lt tank it is solid very secure[ the orange ones]

Purefreedom do tank cages, 400l tank cage with Battery tray, and pump + varistream mounting for £299.

I've done the same and the strapping points in the Transporter are quite secure but isnt the force in a accident multiplied by ten or something?  the straps may hold but if not supported by a cage the tank could split and move forward hmmmmm got me thinking now :

does anyone strap an UPRIGHT  650 litre tank in an expert/scudo etc.?

Cheers.

I have 650 lay flat in dispatch
secured by two thick metal brackets
(made to measure by local metal fabricator)
cost about £25.
one is front to back-other side to side
then got my mechanic to bolt them through chasis.
Job done

10? Try 66x (650l) : 42900 KG of weight, straps are not the way to go (for me).

Even though those excessive forces last a split second usually, a split second is all it takes for something to snap really.

how would i secure an upright 650 litre please

Ive got a 500lt in my hiace and also have a bolt and plate straight through the chassis

Tank cage is your safest way. Contact Andrew on 01472 347519 or purefreedom@adepta.net.

GQC - it all depends on how fast you are travelling, how sudden the stop is, etc etc.  F=MA Force = Mass (KG) x Acceleration (derivitive of velocity m/s) - when you apply your brakes you are accelerating in the opposite direction to which you are travelling.  You know how when you brake, any bottles etc on the passenger seat go forward, well they are accelerating in relation to the seat.  so if you crash, lets say headon, then you have a massive acceleration in relation to your seat, and thus the tank experiences the same acceleration, or 'g' in relation to the van.  for example, when someone talks about experiencing 5g in a crash, that is a force exerted on them which is 5x their own mass (not weight, different thing) - my mass is 100kg (fatty!) but my weight is 9.81(m/s^2)x(100kg) = 981N

9.81m/s^2 is gravity.

sorry I'm going off on one.

more mass x more acceleration in opposite direction = more resultant force.

even simpler, 400kg decelerating from 30mph to 0mph in 0.8s = 32tonne/s

so should i forget about wfp

No, but I wouldn't advise strapping down a tank to the eye bolts - its the eye bolts which aren't up to the job, straps are fine if secured to a steel plate (bolted through the chassis ribs with hi tensile bolts (8. )

nothing to it, just do it safely.

Thanks for that Alan, I knew that but it's sure nice to have it typed out like that, I couldn't word it.

i have a 650 litre upright tank in a vivaro its secured by  an angle iron each side which is bolted to the floor with another iron plate underneath the floor and then secured with 2 5 ton straps on the angle iron its very secure regards alan

Thanks guys,

Looks like I will be changing the way I do things!

Basically just bung it in anyhow.

If you crash it you're stuffed anyway, so save yourself all the bother.
