What's the height from the floor to the top of the ram on a Bridgeport
J / 2J vertical mill?

Reason I'm asking is to try and determine if a Harbor Freight shop
crane (2 ton) has enough height / reach to slide under the end of a
trailer and lift it up off of the trailer. The other alternative is
to slide it down a ramp of some sort with a comealong winching it
down. I'm not thrilled about sliding a top heavy item with a narrow
base down a ramp.
