Entirely agree that lifting from the top is far safer, especially on your own.
Do verify the thread for the lifting eye. Bridgeports can be found with both Whitworth and UNC, imports could well be metric. Its worrying that the size is such that the wrong thread may still seem to fit. Obviously get a proper, certificated eye. Some of the bargains from "who they suppliers" are a bad joke.
I'd pull the head off completely as it gives better access to the top eye and reduces the weight.
From the square base casting that looks to be a series 2 Bridgeport variety not the normal series 1. Lots heavier and beyond the capacity of an engine hoist. Gantry crane time. If you have a roof beam sufficiently close to the right position a short RSJ attached to it and held up by acro props so the beam doesn't take any real load, just a acts as a stabiliser, may do the deed.
But then you can't swing the machine for positioning. Drop it on 1/2" or 3/4" round rails to slide into position. Prybar lift to pull the rails is safe.
I slide my Bridgeport on 1/2" rails if I need to move it and use 4 modified car scissor jacks to lift it via brackets held in the bolt down eyes by rawlbolt expanding anchor studs. One piece bracket across the front, separate ones braced against the column at the back. The brackets are bolted to the (ex-SAAB 900) jacks. Slow process but safe enough if you keep it pretty level. If I had to get a pallet out from underneath I'd initially lit it just enough to let teh pallet move and stack piles of 1/2" or 5/8" cribbing under the corners. Doing one at a time. Then I'd go round one corner at a time lifting just enough to pull one piece of cribbing and dropping back onto the stack. So the amchine stays pretty level at all times.
Really slow job and, frankly, need to be out of other options. But my experience is that it can be done safely.
