Looks good. I had to make a couple for my wife's mother. One is a small one like yours to be able to get her wheel chair down a short step. The other is 12 feet long that we use to push her wheel chair into our house which has a couple of steps and a 24 inch rise. I used 3/4" plywood and ripped a 2 X 4 with a matching angle at the bottom edge so that it 'dies' into the floor and there is no hump. I didn't have Sketch-Up at the time. I bought a book but have not taken the time to learn enough to be proficient.

Thanks for the suggestion, Tom. Since the wheels on the chair are big, I don't think it will be a problem. I will test it later this morning.

Something you might want to consider is adding curbs to the sides......just in case. Per ADA or OSHA....)I can't remember which) said the curbs should be 2 inches tall. Nice safety feature in case the chair doesn't move straight up or down the ramp.

Thanks.

This is only a temporary situation. Mom can't handle the chair by herself. It is either us or the caregiver that pushes her. The ramp is wider than the door opening also.

We've got the same situation i.e. somebody has to push the chair. But if you don't start off in the middle of the ramp or veer right or left just a little you could head toward the edge....it's happened to me.
