exactly. Why spend $100 for a cheap electric winch or $400 for an expensive electric winch when you can just add a few more pulleys and make it super easy to lift. Im planning on doing something similar in the next few weeks. With one pulley your are lifting 120#, two pulleys, 60#, put 120 pulleys on there, and you can have your 2 year old lift it up or strap the lift line on your cat and give it a slap on the ass.

With a single pulley "rigged to advantage" you can cut the load in half, and you can connect two pulleys to each other and rig both to advantage for a 4-1 load ratio cutting it down to 30# on just two if you are ok with having a variable aligned hoist (works fine, but definitely not "idiot proof" or intuitive), but I'm fairly certain I could not explain how with just text...

Love my hoist!

We basically copied the Lange hoist and it probably cost us $125 at most. I have left it up there for over a month at a time and inspected and everything looks great. I am quite confident that hanging it for a season would be no problem. We just attached an eye hook to the storage area in our garage and cliped it to the window and the hoist hook with carabineers to keep it from spinning.

And building it was a good bonding experience with my Jeep! I can guarantee that the top loves me for it because otherwise I am sure I would have dinged it up a few times lifting it on and off.

I would post a picture but it says the file it too large. I have no idea how to re-size it....

made a picture in paint...

each "leg" on a rig bears an equal % of the weight, so 4 "legs" = 25% load or 30 pounds on only 2 pulleys. just hafta remember that a floating pulley bears the load of both legs when you factor in ma load ratings on each component.

Same principles apply to using a winch, so a couple snatch blocks can do some pretty amazing things, especially if you have a second cable handy

How did the drilling go? I was afraid that drilling directly into the hardtop would crack it or cause it to spiderweb. Did you do anything special?

No issues drilling holes. I was a little more cautious than I usually am because its thin, but it's fairly similar to a fiberglass boat hull in that its sturdier than you'd expect.
