Take the accumulators off and put hydro rams in there place or better still oil over air accumulators then you can have the best of both worlds.http://www.erentek.co.uk/conv-kits.htm
Thanks Hilly, what about a pump on tractor to run it on air everything is still in place , is it an inexpensive option

No idea but erentek are very helpful and very efficant to deal with, give them a call and they will advise you better than I could. I recently put there conversion kit on a trailer and there parts are very good quality.

The load sensing valve will reduce the likelihood of the wheels locking
Leaving the air will be difficult to fit onto the tractor foot valve, but you will have emergency braking if the trailer breaks away also have an air handbrake on the trailer (as long as the air tank holds air).

Just check it isn't on disc brakes in which case you are buggered, nearly fell for that one last year but managed to extricate myself out of one with discs last year as we only have tractors with hud brakes

Hi speedstar. What is involved with the load sencing valve and how much do they cost.

It is just a valve plumbed in to the pipe work & a rod to make it work, thimk a new one is about the £
250 mark.

I have recently put two hydraulic load sensing kits on newish trailers that were far too jumpy and were developing 50p tyres, with better results than expected, after reading before that such valves can be temperamental.

Valve stops to much pressure/flow reaching the ram if there is no or little weight on the trailer, causing the tyres to drag, flat spots.
As the springs go down with the weight the valve opens allowing more pressure/flow into the ram. You might get away without valves depending on the pilot, but probably best to fit now with the rams, rather than later.

I've used these on our converted lorry trailers. Just bolt on and go!
They do a 35mm ram also which I would recommend.

Spoken to erentek and they were a superb company. Very knowledgable and i have parts coming today. They did the kit originally for this bowser we are creating out of an old knight runway deicing machine.
