Dog, what I want to do in the abstract is to have a load that has two rings on it, one on either side, and to lift that load with ropes on either end pulling horizontally so that the load is suspended in the air and is between two ropes as if it was suspended over a river with the ropes tied at either shore.
I'm starting to think that screw links like the ones that climbers use might be better able to hold a load instead of something round like a metal ring.
