The problem a lot of teams had was the approach.

Many teams used the approach of ramming the bridge with an angle to bring it down.
Although this works fine with a lightweight easily-turnable bridge that most of us built, it won't work with the real bridge.

The reason being, of the torque you had when you rammed the bridge, only a fraction of it is actually used because you're not applying a direct vertical linear push.

Like someone said, having a 2" bore 12" stroke cylinder will do wonders; if you push vertically on the bridge from above, it'll have no issue pushing it down (consider 60 psi with 2" bore - lots of force!).
