Definitely a team lift . It's funny you bring up an overhead crane. I just started contemplating one also .

I haven't gotten to the point I need it yet for my 65# rotary table but I bought a foot pump operated hydraulic lift table to use for such things. It's just a matter of lowering the mill table enough to slide heavy things onto it from the lift table. I also have a foldable engine hoist I used for removing the heads from my Bridgeports but it requires to much clear floor space for casual use.
