Lots of ways to do this, but I have one of these:
Here's a youtube video showing how pry bar and wedges works to get a machine up far enough to pallet jack it:
I put a 2000lb lathe up on pipes with that bar. Easy physical work, just nerve wracking the first time making sure everything is safe from tipping on the way up. A Bridgeport is also top heavy. Take it up in as many steps as seems completely safe. It doesn't matter how long wedging it up takes, only that it is done safely without tipping because once you have it high enough to get onto whatever you will use to move it the rest of the job is hopefully much easier from there.
