Looks like an awesome machine. Very cute and strong. How do you lift
the vertical columns inside their ways? What s the caster rating, they
look like 600 lbs casters at best?

I would also calculate the stress on the bolts tying the top beam to
columns, if you move a 2 ton object sideways and hit a little bump.

If you need a 2 ton Harrington chain hoist for $99 plus shipping, let
me know. 20 foot lift.
