The bridge ... moves?

I need to check with some other teams on a potential problem we have discovered regarding the bridge. We have driven our old robot over the bridge repeatedly, and have noticed that we have to re-seat the bridge on the bar on which it rests after a few minutes of play. Has any other teams, with a compleated field, had this problem? I wonder what FIRST will do about matches where the bridge doesn't actuate because it has been moved off of its seat.

Jake,
Our team has just finished building our bridge and goals and our bridge doesnt need to be reset when the robot has gone back and forth over it, sorry to hear yours does, just my 2 cents....

Ours doesn't move either.. and we've been playing on it with last years robots and walking back and forth, etc...

I would double check the width between your pivot brackets (we have 6-7/16" from outside to outside side of the angle iron bracket).. and ensure that you have the correct thickness angle on the piece of wood (which runs along the floor and the bridge sits on).. and also that you have the small angle on that board that sticks up on each side to keep the bridge from moving side to side (since it should only move up and down)..

that's my only advice.. double.. triple.. quadruple check the prints.. ours was a bit screwed up until the Assabet folks helped steered us to the right dimensions and etc..

Would one of you be willing to post this information? our bridge is still under construction and it would be helpful not to have to do it over.
