One key thing about placing the bar underneath your robot is the tipping factor. If someone latches onto it, it could tip your robot sideways. Though this isn't a problem for winch systems, arms could get busted off sideways. Also, if someone's hook slides all the way over the side of the bar, it could get caught is some things that maybe it shouldn't.

I think it might make sense to put two supports on the bar in addition to the end supports. This would allow suspended robots to stay more or less in the center of your robot, and it would provide more support to that bar.
