Well few builders will put a beam in larger than necessary to carry the
weight of the structure. You need to know what it is already supporting.
Once you determine that, I'd still put in a vertical support under the beam
while I was doing the lifting.
And I would make the vertical support have a very large base
in order to NOT crack my concrete floor with a point load.
