One down side here, is that the "ball-lift" must be shut-off when the
bridge is raised, and the controller for the ball lift is on the
"bridge" (other) side of the opening. But, along those lines, if
there is a bin to catch lose balls, the bridge could just lift up,
and disconnect the ramp at both ends. Then, when the bridge is on
it's way up, balls just roll back across the ramp to where they
started, and into a holding area...
