Hello,

I have have sort of an engineering styled puzzle that i thought i would throw at you guys :-)

I have almost no room between my milling machines spindle and the ceiling in my shop. But i need to somehow put around 4000kgf on the toolchanger to change tool in the spindle. The pneumatic cylinder that came with the spindle is something like 40-50cm long, but ideally it should be no more than 10cm...

I've looked at "pancake styled" pneumatic cylinders, but i cant find any that can push that hard. I've looked at hydralic cylinders, but the whole hydralic system is rather complex and expensive... i thought about turning the pneumatic cylinder up-side down or sideways and use some sort of lever, but i cant seem to find any good solutions...

So... are anyone out there having a good and simple idea how i could add 4000kgf to the spindle and only take up around 10cm?
