How big water tank would you be able to put in a 1200kg payload vehicle?

[clean]

Matt,here is a conversion chart
http://www.onlineconversion.com/waterweight.htm
best thing do is find different size tanks and their weight (empty) then add the water weight to that,then all the rest of your equipment weight,add it all up and see what the result is
then have a boogie

1 litre equals 1kg roughly if that helps

No it isnt. Go to that site, 1 litre to 1 kilogram

the statement IS wrong. 1 litre of water equals EXACTLY 1 kg

boo didley i was trying to help the guy thats what this forum is about only when you where challenged by sensai did you decide to post again otherwise you where offering no help whatsoever 

[Niall McAllister]

Sorry about your hang over.
Lighten up.
It was just light hearted.
get over yourself.
  (smilies, Even this is not meant in a serious way)

anyway no one actually answered the original question, so how much help did you offer?

anyway to give an answer, Matt I would say 1000 litre would be too big, what with the weight of the tank itself and you and your other gear.
you probably would want to go to about 800 litre max
but that would just be me erring on the side of caution

Hope that helps

Ive got a traffic (1200kg payload) and got a 650lt tank...........
1 lt water is EXACTLY 1kg so

650kg - water
80kg - me
100kg maximum - Diesel for van (not 100% sure if this is factored into the payload?)
100kg (guesstimate) poles, cage, cleaning equipment in back of van.

That all comes to 930kg.

That leaves approximately 270kg to play with, so you could easily get a passenger in if you need to.

If you do fill the van to the maximum capacity you are running the risk of breaking the law if you go over and as well as that you will get less miles per gallon.
As a rule I only fill the diesel tank half full each time so I get more mpg

I do have 1200kg payload and a 800ltr tank.  If I've got full equipment on board, a ladder on top, and plenty of diesel in the tank, I'm borderline.  I'm also overweight which doesn't help  .
I leave the water level down maybe 100 litres or more normally.  If I have a job coming up where I will need to fill right up (very unusual), I plan ahead and ensure that the diesel is low (it's a 90 litre tank so makes a difference).
I did check this out on a weighbridge shortly after buying the van.  I weighed it with me inside, all my equipment, a full tank of diesel, and an empty water tank.  To put 800 litres in would have been a bit tight but doable if unloading other unnecessary stuff and keeping diesel low.

Agree with leapstallbuildings.

Have 600l tank in 900kg payload van and with me, full tank, ladders and bits and bobs I am on the payload limit according to weighbridge.

Go for 800l tank and you should be OK, or 900l tank but don't completely fill unless necessary.

If you want a hot system that woul be extra weight though.

max 800 would be safe limit imo

you then have the 400kg for you and a person, fuel, the tank frame, the tank pumps hoses ect ect. they really do add up,

I weighed a hose reel at about 15kg each is scary how much weight we do carry

average person about 85 kg
tank 25kg or more
frame 10kg +
fuel half full 40kg
pumps ect say 10kg

thats 180kg and have not added other stuff yet like the hose reel. if you have a 2 man set up soon mounts up.

Having a larger tank and filling it only when really needed is not a good thing is stupid idea.

Depends really IMO.  Stupid idea if it would cause overloading.  Not stupid if it gives extra carrying capacity (legally) if you can plan ahead and run the diesel down, offload equipment weight that isn't needed for that particular job.  By temporarily trimming down what is carried, it could give an extra hours work - possibly a bit more.
Of course there is then the temptation to overload but so long as that is resisted there should be no problem.
Personally, I prefer not to push the van to the maximum all the time anyway.  I doubt it does them any good - particularly those of the dodgy gearbox.

I guess it depends on whether a 1 or 2 man set-up.

1 man you could carry upto 900l.

2 man upto 800l - largely due to weight of passenger.

This would be the maximum amounts you could carry and only way to know for sure is fill it up and put it on a weighbridge. I got stopped by police once becuase they thought van was overladen and I showed them the figures from my weighbridge test and that satisfied them.

As a 1 man band I find 600l adequate, but if you do large comercial jobs then 800-900l would be useful. The only time I have to go home and refill is when I am doing blocks of flats.

[macmac]

don't forget things like, roof bars, ply lining when adding your weight up. Anything on that van that wasn't on when it left the factory.

800 Ltr max for one man set up IMO

macmac I have 1 set of 3m double wooden ladders, rhino triple roof bars and roller plus trad gear, plylined, and 600l water with me in van is right on the limit of payload (900kg). So in theory take of 300kg from payload of van to give max tank size.

Other factors will come into play such as weight of driver and tank (mine is heavier than most because it is 10mm thick polypropylene and honeycomb baffled - unlike brodex). Only way to be sure is to fill van and put it on a weighbridge. If you are a bit over just don't fill tank to the brim.

Ok so if a pauload was 915kg then using this formula the tank could be 615litres ..... or 650 not completely filled up.
That is gonna be the deal now as i am no longer getting the 1200kg payload vehicle but a 915kg one.

Should get away with it if you lay off the pies    ,are frugal about what equipment you carry and just to make sure, put diesel in lesser amounts and more often.

If you ever took your van to a weighbridge Ewan you would know that the front and rear axles and total weight are all taken seperately, so you get 3 weights which you then compare with the total permissable weights for front axle, rear axle and total vehicle weight given on the plate on the vehicle (on mine inside the drivers door).

My front and rear axle weights were well within the limits, but the total vehicle weight was right on the limit.

This does highlight the importance though of positioning tank as centrally between the axles as possible.
