Just my $.02:
Don't do it. I am one of those who had the thing tip over, even without
modifications.
Other posters have commented about the weight swinging from side to side
and upsetting things.
You haven't lived until you have had that happen. A 1500 pound pendulum
can do a lot of damage.

Several times including this morning I have written and then deleted a
description of how to make a lightweight portable collapsible gantry lift
with the beam suspended from folding tripods.

I didn't post them because mine have collapsed at the wrong time, and can
fall in any direction, so don't do it.
