I should say that I don't normally move machines around in my shop - at least not the big ones. But they are all designed in some way to get a pallet jack under them if required.
My shop is in my basement, and I have gone to elaborate ends to fit the equipment into the space. If you're at all interested in that saga, have a look at this
Basement Shop Setup.
My large European woodworking equipment is all designed to accept a 21" wide pallet jack under the chassis. I designed the stand for my PM1340 specifically to accept a pallet jack under the bottom rails (
Custom PM1340 Stand). My current mill is a Rong Fu 45 (the real deal) and because I have 83" height restrictions in my shop I have it on a shop-built stand with integral pallet as mentioned in my post above. Here is a photo of that (excuse the mess, I'm chewing up aluminum by the bucket today).
Nothing fancy about it. Two layers of 3/4" baltic birch plywood glued into a sandwich sitting on two stringers that are 4 x 4.5", also glued to the plywood.
I will caution you about moving large machines like this around on a routine basis. Unless you have one outrageously stiff stand for the PM1340, you are likely to throw the bed/headstock out of alignment when you move it around with a pallet jack on anything but a very flat floor. Twist in the bedways is a quick way to convert making a cylinder into making a tapered cone.
Although I can move my 1340 with a pallet jack, I leave it stationary until the floor needs painting. I plan on replacing the Rong Fu with a 935 soon, and due to ceiling height restrictions, I will not put it on a pallet, and instead let it sit on aluminum 4" round bar slugs that penetrate the wood floor and go down to the concrete into epoxy - much in the same manner I did for the 1340 as shown here:
Hope this helps. You might also look around at some of the other posts for the 935. Lots of people have fabricated a stand with big casters to be able to move it around.
