The dr is sending me over some info this evening 👍🏽 Can’t be arsed with dropping the machine off spending £600 on a thumb which may or may not stay on I’d have to get out and flick the diverter valve first so no one of the ground chaps can push the connectors on 🤣 not going for a rotate as with the build height already Keen from the tilt hitch I don’t want to add to it
Get top bracket made like this so you can turn it

Pin centres are to tight on a 216 to do that unfortunately !
Worth trying to make the top plate bolt on in both orientations though, not a quick swap, but will be worth moving it round sometimes. Or make an adaptor up, but that adds weight.

Fair play to you stop pi**ing about and just do the job right 👍🏻
You might think it's a lot to spend on an attachment but once you've had some use it of it you'll never worry about that again.
My Cranab grab has had some use since I had it S/hand, in ferk knows when. Handled hundreds of tonnes of gert rocks and couldn't have done without it .. a grab is a good investment, whatever type it is

very nice
I’d be itching to put those nice rocks into a nice retaining wall if they were in my possession.
they went into a retainer boyo .... in a lake .. shoring up a bank with a house on it .... a lorra weight in that lot ... was loading out into transport for two days - two vehicles running back and fore, but hour plus turnaround ... two days later ......:oops::(

Looks good, make sure you get some action shots of it. I take it you can switch the orientation of the headstock around so the grab works in the other direction?

I sure will ! Typical the machines out on a job it’s been sat in the yard for a week 🤣 yes it’s just 4 bolts so easy to turn it around. Maybe add a rotator when I start saving again 🤣

You want to put a check valve on the close side Boyo ... made the world of difference to my Cranab ...... once you've gotten a grip it just doesn't let go .... before fitting one it'd lose its hold fairly quickly

I’ve got a Cranab (branded Rototilt) timber grab and a smaller Tigergrip ‘finger grab?’ (open ended tines, 3 meshing with 2). The Cranab has an inbuilt check-valve and the Tigergrip is bare-bones, without. The Tigergrip holds consistently - once it has hold it doesn’t seem to budge - the Cranab can’t really be relied on sadly, it doesn’t grip as well.

I'd be putting a clock on the cranab to see if the pressure is actually being held ... sounds like it isn't ..... mine with / without is worlds apart ... great grip without, but bleeds pressure back without the check in circuit .... you've all seen some of the rocks my cranab's picked up for me .. once it has a grip it doesn't let go, with the check in place at the ram's port.

My Cranab (which is smaller than yours) is very good, and has done a lot of work for me.
It’s never really inspired confidence in ultimate hold though, but that is probably because it is undersized for what I’m asking of it a lot if the time! (Timber grabs are designed to entirely surround their load, and that pretty much never happens with me as I am both greedy and tight so can’t/won’t buy a bigger digger to carry a bigger grab!).
However, the smaller Tigergrip seems happy grabbing hold of (and holding on to) equivalently oversized pieces very confidently - you ‘know’ when it has them and it doesn’t seem to slip.

it was rare that my Cranab could get its tongs around anything I asked of it ..... were usually gripping with their edges, sometimes almost at full opening, but once that check shut off, it stayed put
