I'm a 617 mom and wanted to comment on the design with some help from my son. The dumper door works like a roller shade using a window motor to lift and lower a bottom weighted tarp. A vibrating system helps to release the balls from the hopper. It's not top heavy because the sides are made from aluminum screen. They are using the side wheel conveyor because it can extend farther inside the hopper. They are going to fix the bumper issue.
