Hi there, I'm operating a hospital visitation program at the national hospital in Nairobi, Kenya. I'd like to make a pulley hoist for lifting patients out of bed. Any suggestions on a pulley system which would effectively suit that job? I'll be using metal pipes for the structure to attach the pulleys to and I'm still a bit unsure of how to make the base stable enough to support the weight of the patient while being lifted. Any suggestions on that would also be helpful. I'm also happy with relevant website tutorial suggestions, as I've already done a bit of searching but I'm having trouble finding specific do-it-yourself tutorials. (most of the stuff I found is about lifting bikes or kayaks.) I did manage to find a picture a patented hospital bed pulley system which I could use as inspiration for a design, but I'm having trouble understanding how the pulley system works. Every time I try to follow the rope I can't find where it ends! You should be able to view the image of the pulley system on the link below.
