Home Built TiltRotator

[HeliPilot]

Following on from my introduction...!
My hydraulic knowledge is very limited and my terminology will most likely be way off.

JCB 8026 Mini Digger: I currently have one proportional aux control via foot pedal or right joystick. (A push button on the left stick changes from one to the other)
For the tilt rotator my plan is to mount a couple of proportional valves on a two station manifold to the tilty and supply the manifold via the current aux circuit.
I have installed a roller button to the left joystick which will control the rotate prop valve, and the right roller will control tilt prop valve. A switch/controller will disable the current right roller function (Aux) to enable use for tilt function only.

My question is what would be the best way to supply fluid to the manifold? (I have assumed this needs to be constant from P to T)

 

[CPS]

It's not a constant feed its proportional as and when you move a roller. This is where the control system takes over and where the cost is involved.
A constant feed will cause problems... mainly heating the oil and slowing the machines movements down.
A simple controller could mabey be built to do it?

I'm working on adding proportional 2nd aux to my little Tak. I found a good deal on the proportional valve and it looks like it could be used on anything.... Now I'm looking for a joystick with the thumb wheel and I'll probably buy the extra valve block new.

Assuming you`ve not bought a proportional valve setup yet, (if you have what are you using for the electronic control system side of it?)
Could you use a solenoid diverter valve fed from you machines proportional aux supply, and a push button on a joystick to swap between tilt and rotate? You wont be able to tilt and rotate at the same time though.
Or cetop valves mounted on the tilty and push buttons again on the sticks, 2 on each stick (tilt left/right, and rotate left/right) again fed by your machines aux, using this I think you should be able to tilt and rotate at the same time, I think @V8Druid and @TiltyShaun controls are similar to this.
Both the above ideas could have an extra valve added for an aux outlet on the tilty.

I beleve I have the electronics sorted out and I woild like to use the machine aux in a similar way to how Engcon fit DC2.

A joystick with thumb wheel is very expensive, if you have Rexroth type grips you can 3d print the removable cap?
Then just look for the roller button to fit.

 

[Keif]

It's been 10+ years since I've done one, but #2 looks just like the camshaft adjuster solenoid for variable valve timing on the 5 valve Audi and VWs.(1.8t and 30v v6)

Thanks, I'll check that out.

Here is are the valves. From looking at the diagram they work like a pilot valve, and main flow comes from the valve block.

I'd like to know more about your control setup, I might be better off going that way long term. Right now I want to run a tilt bucket and thumb at the same time, not switch back and forth.

Looking forward to seeing more of the rotator build!

welcome to the forum.

where did you source the Rexroth type roller from? Thanks.

welcome to the forum.

It came off a faulty loadall joystick, the engineer changed the whole grip complete with buttons.
They are dificult to get hold of.

We've done a couple one rasbury pi and the other Arduino. we are just looking into turning them to pcb boards

Do you have Rexroth type grips?

Have you checked to see if there's any spare wiring and such on your 8026, just thinking if there was a factory option of extra aux line there may be some wiring already in ready.

I have checked but haven’t found any spare, took me ages to find where they bury the controler.

And it's made so much easier by all the yellow wires.

 

[HeliPilot]

I have trolled through them trying to figure out the controller functions and if it does have a spare capacity for 2nd aux

 

[Regy53]

This is the sort of thread I have longed for . That’s some
Skill you have to be making your own tilty etc . Looking forward to the updates

That's good if you have the electronic side sorted.
Possibly the tilt rotator manufactures controllers have an extra control over the ones needed for the head, which activates a solenoid on the aux line, only to provide oil down to the head when needed, to save oil overheating and slowing the machine down as @CPS mentioned.

yeh spot on @craig .. 3 x cetop3s, manifolded, in me VA-r plus a hitch valve too ... fed by a prop. aux pedal ...
buttons for tilt, rotate & Aux .. toggle for the hitch function .....

the issue is finding a small enough rotary coupling to transfer the fluid to the lower half of the set up ... I found Roemheld make some excellent rotaries ... 2, 4 and 6 gallery .. but at a price ... they can be found on ebay s/hand at a lot better rate than new price though

this is a 2 gallery https://www.ebay.co.uk/itm/Roemheld...051670?hash=item4219d24316:g:qFQAAOSwZtNa1ilY

this is a dinky one and cheap too ... 2 gallery though https://www.ebay.co.uk/itm/Roemheld-New/133141829556?hash=item1effdf17b4:g:Y4IAAOSw5cNYfSLz

and a 6 gallery ... not seen one like this before . https://www.ebay.co.uk/itm/Roemheld...094100?hash=item1ef8237c94:g:YR0AAOSwNSxU2U1n
.. my four and six gallery spare ones I have are all the same as the first link but taller ... the one I have in my VA-r has been performing fine since it was installed several years ago

ON EDIT ... that first link looks like a 4 gallery on closer inspection ... has an A and a C port so must be 4 gallery
'bout a quarter of new price that

When we disable the right roller at the same time we can take control of the current proportional valve to supply oil to the head.
It’s fairly strait forward to perform this function on demand only. For tilt & rotate.
Only when the titrotator is in use our JCB ECU is disabled and our ECU becomes active effectively taking over a few more controls
