Similar to the gradalls in American, only it's the dipper not the boom that rotates.

Still won't tilt though....

But that with a tilt hitch would be just about the lowest build height tilty you could get. Albeit the tilt and rotate would be back to front. It does seem a pretty logical next step though

The main benefit would be you’d have all the breakout of the bucket ram available for side on digging

But would you get oil through the rotator for tilt and aux?

I think the motor would be better pointing towards the cab too - looks a bit exposed there.

I’m guessing there’s a fair bit more room there for couplers than on a tilty.

yeh - plenty of room for a bigger multi-gallery rotary coupling
