terry, I think the miracle of the wheel comes into play here. The meat 
is just rolling not being lifted. Reason would say that there is no way 
that I can push  my Dodge 2500 by myself, but I can.

For the bigger ones there might very well be some sort of gearing going 
on. As to the chimney draft powered one that I saw, for all I know all 
it might have been used for poultry. I only remember one set of gears on 
that one.
