I built a set of 10 foot rampsout of 2x8 with a 2x6 running down the middle of the bottom & one inch pices of 3/4 inch plywood a foot apart for traction. I plan on making a pull down ramp that I can lower from the celing with a rope. Like a draw bridge.Thats actually a pretty cool idea. How you do you get it up and down, do you have a bi-fold ramp?
I have a small comealong (spelling) LOL I plan on using. I guess Its going to be put on hold till after the hip gets better.That space is cool, and scary at the same time. When you build the ramp just be sure you don't have all the weight on the existing shelf. I would make a separate support just for the ramp. Also a cheap 120volt winch would be perfect to raise and lower it with no effort. Check out like Harborfreight tools. Can usually find one for like $60 and a 1500# will be more than enough. Sorry, just my habit. I'm a builder by trade and when I see things like this I always get into it. Nice Job, Let us see when you get the ramp done.
