If possible, I would raise the ceiling in that area.

But maybe connect an air cylinder to a screw or cam and rotate the screw with an arm connected to the air cylinder. That way, the cylinder would be mounted horizontally.

Can't raise the ceiling....or rather, i've realy done that...there is no more to give, and i'm still 20-30cm short....

I've been looking at making a sort of cam, but the amount of force worries me a bit. First of all there is a ring which pushes down on the pressurering on the spindle, this ring needs to be hold in place, which is done by the cylinder in the original setup. So i need to keep this in place somehow...with 4000kgf on the end of it :-/

I've attached some pictures of the testassembly i have at the moment...and where the pressure ring is that needs 4000kgf to push it about 10mm to disengage the tool...

Forgot to mention the second issue: Most of the rollers etc i can find for a cam-based solution is nowhere near strong enough to handle these kinds of loads and still have a reasonable size...
