Put the contents of the boxes, which are going to have to be square if not cubes, in circles. This way…
Wait. They’ll have to be circles in circles. Linkage between to keep the spacing. Inside each circle is a free wheeling circle. The circles will have bearing mounts on the (back? sides?). The fronts will have linkage to their neighbors. I think this will work. Power will still be an issue. That and volume. Did I save space?
I think this idea still needs work.
I’m also not all about the idea itself. Not the rails. Not the motion. Not the mechanics.
I think I just like the idea of reduced footprint. I could do a reduced footprint to a much lesser scale with a chain hoist. Seeing as how my operating height, assuming a standing position is about 3.5 -5.5 feet, then I could have three units that too up the space needs of one.
It’s an idea.
