Using sensors, my guess is it's hard to tell "how well" the bridge is balanced. Unless you can figure out the force being exerted on the cylinder, I suppose. A gyro would return you that you're level the moment you went up, regardless if the bridge would balanced if they brought the cylinder up. However, if you can judge the moment when the bridge truly levels out and the cylinder does less work than before, you could automatically decide when to bring up the cylinder.
