How do I insulate a crawl space on 44" beams?

I went under my tenants crawl space in hopes I could insulate it for this winter. I found out my house is not on your typical 24" floor joists. It is on 4x7 inch beams with a little more than 44" of space between each beam. I think twine will sag to much to keep up the insulation. What is the best way? Any help is appreciated.

If you have that much spacing between beams, what is holding your flooring up? Flooring is not attached directly to the beams, and a span of nearly 4' would require a 3" thick floor to keep from flexing.
