Heres a thought. Just have the slope going in the other direction. That way when it lifts, the balls keep rolling the same direction. (Faster and efficient!) If the raising is too bumpy, just find a way to place a third or fourth overhead rail keeping the balls in,
Unloading the balls at the other end take some engineering. You could have the
rail mounted near the rotation point, (and possibly lower the rotation point and
put on a heavier weight). Or you could use about a foot of flex tubing to make
it all work far away from the bridge's rotation point. See what I'm saying?
Nice work by the way :-)
