Having bought a pressure washer, looking for advice as to setting out the trailer.
Trailer is an ex army trailer, very solid with hydraulic brakes.
Next step will be boarding it out  with water proof sheets, the floor will be 2.5mx2m

thinking about putting machine over rear axle, and a water tank towards the front to aid balance.

Anyone any thoughts or advice

Putting a pic on this bloody site is getting a pain

You need to consider you need the nose weighted when towing but its not so important on a twin axle trailer. I'm building a single axle trailer which will have the tank washer and boiler. The tank will be in the middle, the washer at the front because it weighs more with the boiler at the back - that way no matter if the tank is empty or full it will always be nose heavy and handle nicely

what size trailer would be sufficient to use as a setup,     i havent got a van so been thinking this way, use my focus estate car too much as a family transport, otherwise i would have a van.  the nose i take it is the fitting to the tow ball.   fix a mesh side with tarpauline to keep prying eyes out.     lots of trailers out there on ebay to pick up. ,  if anyone has set a trailer up to transport there pressure washer setup,  can you post some pics,  if not can you send some to  ts1cleaning@gmail.com               give me an idea,  cheers

The trailer is a Sankey MOD trailer, single axle on landrover wheels.
It was used for carrying bridge sections.

I think the nose has to weigh 180 kgs, i did google it, it is somewhere near that.
Once I have machine on, I will take it to mates weighbridge and weigh it, then
fill and adjust till get it balanced.

It is just a chassis at the moment, getting some flooring tomorrow, and all the angle iron I need.

I will be towing it with my Hilux, max train weight is about 5150kgs, hilux weighs 2150 with just me in it.

Trying to resize pics, will post them when done.

Thinking of putting a lay flat tank around 4-500 lts on board

that is going to put some serious weight on the  rear axle of your van, there is only room to fit the machine over the rear axle everything else will be forward making it very nose heavy.

i would try and find a big pneumatic jockey wheel to make it more memorable

[Andrew Briscoe]

Hopefylly machine will be slightly to the rear of axle,
was thinking of small tank but travelling empty, and filling on sight.
Not as heavy as it looks, just need to get balance right,
new ribbed jockey ordered.

[Andrew Briscoe]

Have taken around 2' out of the length, now making an 2.5x2m bed to take machine
and water tank.
Any advice on size of tank, was thinking 350lt lay flat tank, would this size be ample for most jobs, obviously with a hose fill to keep up with flow.

Are they air brakes/air over oil? I can't make out from the picture or is it the suspension ?
There is a place that build tanks for i think boats.They are plastic this will help with the weight issue. I will see if i can find the number. Possibly two tanks ,one on either side will help with weight distribution and keep the centre of gravity low?

[chris scott]

Found it   http://www.hendersons.co.uk/boattank/plastic-water-tanks.html

[Mike Halliday]

2x175lt tanks against wheels with the machine in the centre, tool box at the front.

2 metal struts running across the top of the tanks to give the tanks stability and to fit a live hose reel

[Andrew Briscoe]

The brakes work simiar to most trailers, the hitch has a shooting brake, which works the
brake fluid through a slave cylendar, the rubber spheres are like buffers for suspension.
Being military it is probably over engineered, chassis is galvanised.
Sruggled with a mig welder to spot weld it, getting a stick welder into finish it.
Nice one Mike, never thought about tanks over arches.

Are you changing the hitch, why did you shorten the chassis??

Rob

[Rob_Mac]

Couple more questions

Which machine are you using with it and because you have the use of welding gear could you not put a lay flat onto the base and weld a support structure above to hold the machine. Get it all over the back axle then??

Rob

[Andrew Briscoe]

Having to modify the hitch, altered length to reduce weight, also all the weight would of been towards the rear.
Have shortened the suspension arms to lower/level the trailer, as it was high at the back.

Quite a bit of work and cost, trailer was only a few hundred quid. at end of day I get trailer I need.

More work being done tues night, will try post some more pics after then.

Don't want that over a tank then.
