How to Prevent Chain Bar from warping under gravity?

My team is wrapping up the building of our robot, and we are currently struggling with our chain bar. we have it mounted on top of a four bar so that it can reach the top of the tall yellow goal, and operating off of one motor. When it picks up rings, it tilts down on the side without the motor. I expected this, but is there any good way to decrease the effects it has? I know I’ve seen crossing metal bars as support, does this do anything significant for this problem?

Do you have any photos? Normally I’d say to just add bracing, but I’m not sure what it looks like. I hope it gets straightened out soon!

Simple - change the gravitational constant of the universe locally… Q says you have to redefine gravity. - YouTube

Cross-bracing is a good second choice.
