What size tank can I put in my expert 900kg payload? considering a litre of water is 1 kg, then weight of poles, hose, batteries, pumps, varistreams, reels, tank weight

[Davew]

Take a 650ltr tank - you wouldn't want any bigger if your solo.

[Luke Johnson]

I might have 2 men

[Luke Johnson]

come on people!!! reply

[russ_clark]

650 is the best you can safely do with that IMO

[Luke Johnson]

thats what I was thinking

[AuRavelling79]

650L

[Alex Gardiner]

2 people at 80kg each = 160kg
ladders, bucket, hose reels = 40kg
tank of diesel = 60kg
4 poles = 10kg
650litre tank = 35kg
water in tank = 650kg

Total = 955kg

Result overloaded and a hefty fine.

The maximum size tank you can get away with is a 600 litre or just be a very good boy and never fill your tank past the 600 litre mark. Make sure if doing this that you have a clearly marked maximum fill line just in case you are stopped.

Alex is quite correct, but he did miss one thing and thats assuming you have your tank if a proper frame you WILL BE Heavily over weight

The largest i reccomend is a 500ltr R/O or D/I and thats with a full frame.

Ditch your mate, leave your ladders at home and keep your fuel tank half full easy.

if its 2 men then I'd recommend a 500ltr tank, if you're on your own then a 650 is fine.

[stuart@skypole]

sorry i think thats bad advice.

water weights 1 kilo on an average day with average tempreture

the guy will probably get fined

i have the 800 pay load expert, and have a 450 ltr tank. i dont fill it right up and i dont think it is over weight.  Handy to know that working out though. 1litr = 1 kg simple!!

[philhart]

If you are looking for a tank I have a 400L upright tank in a frame that has never been used, supplied by pure freedom it was to go in my Fiat Scudo which is the same as an Expert. Email me if you are interested Philhart8@btinternet.com.

[ok cleaning]

no more than 600 lt

Somewhere on the van will be a plate that gives the Gross Vehicle Weight.  (Either under the bonnet or in the door jamb.)

It might just give two figures in kilos, the first will be the GVW, the second will be the GTW (gross train weight) - this is if a trailer is attached.

Put everything in the van, fill the fuel tank, put your two men in the van.  All you need now is the tank and water.

Take the van to the nearest public weighbridge and weigh it with everything including the the two men on board.  The difference between this weight and the GVW is the total volume of water you can have including the weight of the tank.  Tank suppliers should be able to tell you the weights of the various capacities.  Don't forget to allow for the tank fixings.

The weighbridge operator will give you a certificate showing the weight - keep this in the van so you can prove you're not overloaded.

Cheers,

Ian

So will 300ltr be enough for each man ( total of 600ltr ) after first cleans, bearing in mind I will be able to turn water off and I will have varistream, I also am aware that many people use too much water after the first 2 or 3 cleans and in actual fact only  a quck scrub of frames and glass and rinse are required.

[Davew]

 only  a quck scrub of frames and glass and rinse are required.

mmm not always that easy.

[Neil Williams]

Our Expert has 400L flat tank and 4 x 25L bottles as reserve if needed. This keeps the 2 guys going all day albeit with a few exceptions we wfp uppers and trad lowers.

true, but a 650ltr tank doesn't hold 650ltrs, its very close to 600, check for yourself. Even so,

650ltrs = 650kg
tank = 50kg
driver = 80kg
fuel (diesel approx 0.7kg/ltr) = 40kg
4 poles  = 10kg
all other equipment = 20kg (what else you carrying?)

Total = 850Kg and thats assuming a full tank of fuel, a full tank of water and that you are carrying extra gear.  Most of the time the van will most prob have half a tank of fuel, also don't forget that the water level is going down all the time.  Now if you take into consideration that the 650tanks hold 40kg or so less water than quoted that will more than cover the weight of a securing cage for the tank.

I've had many customers come to me with vans that are overloaded and I have advised them as well as I can but at the same time I've had guys come up to the workshop with systems fitted that are clearly too small, all because some 'supplier' hasn't a clue about payloads etc.  The worst I've seen is a Trafic with a 300ltr system, according to the installer that was the largest the trafic payload could cope with.  The system was fitted by a very well known company.
