There is options for a 4.5t tow capacity by going pickup and 5th wheel, although the cost of 5tg wheel trailers is mental.
Don't really know anything about tiltys but could you have the all dancing version in a 3t and then swap it to a smaller machine but run the more basic control system?

Your strait into O licensing then however Brendan. With a license required for both the tractive unit and trailer.... cheaper to buy a lorry.

do it as well as you can,but learn to do it better
nah one o' these RoryIf you do get a engcon, don't forget you need a 360' hat to match
stealth hard hat
or one o' these M43 style jobbies, like me mate brought me back from Oz .... might get an airing Saturday, when I'm out with Russel

that'd take some doing .... the Cetop3s in't tilty wouldn't have it ... all dancing are Prop. and constant flow ... basic are on/off with prop. flow

Yep, I have been doing some research recently on how to get proportional control hydraulics using solenoid operated valves.
It took some sussing out but was actually quite simple to achieve using an Arduino micro controller.
My application was nothing to do with tilt rotators. I don’t know how the various systems offered work but from my experience it’s totally possible to use a single acting hammer circuit to provide oil pressure to the end of the dipper and then fed that into solenoid valves controlled by say thumb wheels on the joy sticks to get a couple of proportional circuits for a tilt rotator. It would just require replacing the stick tops and running a multi core cable down the arm plus the cost of the valves.
Is this what is being done already and have I just reinvented the wheel or am
I on to something?

Well sort of... The expensive bit is the solenoids that can tolerate being driven with a PWM or duty cycle signal. Normal on/off solenoids don’t tolerate high switching cycles or so I’ve read. I had similar ideas of creating a couple of proportional lines on a digger with a CETOP block and basic solenoids but found they would be unsuitable, the reason full spec tilties are expensive is because of the specialist valves rather than the software I reckon?

I might also add that you’d need to sort a power supply for driving the arduino that was stable and also capable of supplying the current to the solenoids through the use of transistors or MOSFET’s as the arduino is unlikely to be able to source or sink the current required for driving a solenoid. Be an interesting DIY project for sure!

yes to all of the above .... looked at it all when I was building ... the prop. solenoid Cetops are a hell of a price - got quoted 1200 quid each and if you want individually variable circuits you need one for each ..... then you need to drive them
... but you would still then need to feed it with a prop. service
..... then you need to drive them so you're saying you can run a Prop. solenoid as a simple on / off solenoid Aiden ???Can't speak for engcon obviously, but it is doable

All this talk about Cetops and Mosfets is going right over my head!!!
As for a 4.5ton trailer, have seen them and agree with Rory, lorry would be a better option!!
I should have been clearer about what going bigger for me means. Currently I find the Kx71-3 very well balanced and powerful enough for most of my work. It is also small enough, just, to go on the trailer with the buckets going on the Iveco. No tacho, no operators licence.
I have 2 big detached houses due to start that have a considerably amount of muck away to load, they are also going to be piled. So something around 7 or 8 ton would be my preferred option. Used to have an Ex60-5 and that would have been ideal. That didn’t have offset dig so been looking at the Takeuchi TB175. So I have been weighting up options and to be fair, hiring in for 6 to 8 weeks is probably the way I will go. It will depend on how site plans develop as could easily put both mine and hired machine to work and give the young lad some stick time in a corner away from anyone else!!

Most tilty wiring down boom is flyby wire as I've in my current tilty have 4 wires plus an earth so there's a lot of things going on in the tilty for only 4 wires as I've got 3 prop valves and a hitch valve

Correct Stu - As Aiden said, he can't speak for Engcon and I can't speak for Rototilt
, but around 80% of our installations are DC2 which is a digital, CANBUS system. The signals that are sent down the dipper are not analogue and, like most CANBUS systems, if the correct digital response is not received, the system will shut down. For this reason it is not possible to switch a DC2-type tilty over to a non-digital system (two proportional lines, mechanical hammer line, whatever)It is possible to switch tilties between two machines of similar size (see my earlier post on this thread) as long as they are within the same weight capacity, share the same dipper or top hitch configuration and have the same control system. It is also possible to swap an SS0 unit around, subject to the same criteria, because there is no control setup in the tilty and the digger is doing the (hydraulic) work. Putting an SS0 unit on a machine configured for SS9 (and vice versa) should work, but you will only get SS0 functionality in either case (i.e. tilt and rotate) and, unless you have a separate quick hitch line (or a mechanical hitch) your attachment will be fixed.
In other words, it might be doable, but it ain't going to be effective.

Did stick length get talked about on your E27? I have been on the look out for a 2.5 tonner for a while and saw a nice E27 for sale and noticed it said long arm on it so are there some options on stick length and would it be best to avoid the long stick if I plan to put a tilty on it ? or isnt it as critical as on say an 8T ?
And have you had any seat time on a Kub U27 to compare to your E27 ?

No, never really planned on putting a tilty on it and short stick would have been weeks on special order I'd imagine.
Not tried the Kubota, but Bobcat specs are similar on paper, there was free finance, and Kubotas are pikey magnets.The finance swung it for me, I'd have been paying thousands in extra in interet otherwise as machine prices are about the same.

Yes it would be best to avoid the long stick, or get a slice made to counter the extra weight of the tilty.

Yup, the E27 I got has an extra counterweight, which is a right lump. It handles the grab and rotator extremely well, I'd imagine it would handle a tilty too.
