same system with a canopyhttps://www.amazon.com/Harken-Hoister-7806-200lb-12ft/dp/B005AUH8OG/ref=sr_1_3?keywords=truck+canopy+lift&qid=1566395032&s=gateway&sr=8-3Says 200lb max on the label but you could build something more robust if you need it (the one on my full size pickup weighs in at around 270 lbs). 8:1 would be pretty key as it that should take you to 40-50 pounds of pull for a full size canopy after factoring in friction.
Thanks for the suggestions. My back can no longer take the lifting and sliding method. I had a pulley system where I would hoist it into the rafters loc the hand winch then slide 2 2x6's under it and lower The canopy on them . But I don't want to drill holes in a new canopy.
So you drilled holes thru your canopy to mount the brackets?
