Pipe a 3 way valve in , so it’s going to return , then open ball valve to give flow , this is how I have pacer booster pump for sprayer piped up , and irrigation bar. And then you don’t also have pipe under dead end pressure

Yes, that would work well, but the way I described worked fine for about 3 or 4 thousand loads with no hydraulic problems before I stopped doing bulk spread fertiliser.

My neighbours timber crane works off a pto reduction hydraulic gear pump. Works really well in 1000 at idle. Lots of speed with little tractor effort. Flowfit do them for reasonable money. Less effort than a donkey engine.

heres one I made earlier ? very useful trailer, we have a set of longer hydraulic pipes so drill or fertiliser can be one man operation
Trial fit, just got to replace the fence posts with something more permanent...View attachment 852272

Looks great! Did you have any electrics on the crane to deal with?
Yes there was wiring for various sensors but worked ok without it

Getting there, still waiting on a 12 - 24v inverter coming to get it going, got the hydraulics running today but all it would do was put the legs down.
Went slightly scrap heap challenge with the headboard, the Fraser trailer bits have been waiting for a purpose for about 10years now.

Please check your donkey engine will operate the hyd pump at the max operating pressure. Most cranes require 300 Bar max to operate them.

If the supply is only say 200bar then it should still operate the crane, but at 2/3 lifting force?

I may be wrong but I think that you may have the HIAB on the wrong way around. We have a HIAB, but not the same model, and it folds the other side.

That's my biggest fear. [emoji27] I looked at a few locally and various ones online, and theyr all different, worst case scenario well need t lift the main post out and rotate the slew stops. That guy I bought it off had never seen it mounted, so we're really none the wiser how it was originally mounted.

Up and running, some minor electrical tinkering was required but goes nicely. Few jobs to tidy up, but that'll do for now, strap box can be done another time.

What will it weigh empty (remembering the max trailer gross weight of just over 18 T)?

3.5t trailer, and roughly 1.2t crane so 13.3t left. So capacity for 22 60kg bags if my maths is right? @Gator was right, it is the wrong way round. I'll fix that another day.
Why do you think it’s the wrong way around?
I have a couple of cranes fitted to trucks and they are that way ie fixed solid at the front and the pivot type connection to the rear

It'll only go about 20 degrees beyond the centre of the trailer to the right then it hits the stops, it'll swing all the way round over the tractor then stop 20 degrees to left of centre. Ideally I want to rotate it 180 so the stops are to the front so I've got full movement to both sides of the trailer and the deck.
Whatever it was on in it's previous life it was the other way around, assuming it was mounted on the rear of a deck rather than behind the cab.
After I had posted had a think a thought that
Mine are both 360 with a slew ring so not got that issue?
Like you said not a big job to swing it around to work over the trailer
But does look mighty fine??
