need a 110V winch
I like the upside down hydraulic cylinder idea. If you did it that way you'd neeed a cylinder with only half the stroke length you plan to lift. You can buy electro-hydraulic pump and resevoirs for a car lift.
If you decided to use the cylinder without cables, you can buy a used hydraulic cylinder with the stroke you're needing from a car hauler.
Better yet is just buy the entire mast assembly from a hi-lo forklift. Around here you can buy these used masts for scrap value. You could even leave the forks on it and weld a steel floor to them. This is probably the cheapest and easiest way to go. And you won't need to build any type of lifting basket or guide rails or anything but heavy mounts on the floor and some way to attach the top of the mast to the walls or posts.

Frank, you got your "Butt Heads Helmet" on? Gonna need it hahahaha
First, taking your numbers, ONLY the first wrap layer of cable will be x". Each successive layer increases the wrap--by how much I don't know---need wire diameter, number of winds, and length of drum--you can do the math there.
And for each successive layer of cable, the line speed increases. Conversely, with each layer, the rated lift reduces (read the specs and it should say, "rated at first layer, bla, bla). And with each layer the amperage goes up too since there is more resistance.
For reference, these 4x4 trucks you see around with 12vdc winches on the front or rear draw nearly 300 amp at the first layer and as much as nearly 500 amps at full pull. Even at no-load they draw 80 amp (yes, and that's DC power but just for example). You may not see a spike in amp draw with that 3hp motor to begin with---but I'm jis' sayin'.

need a 110V winch
Ah yes, safety brakes. Reminds me of when my brother and I were kids back in 1978. My "enterprising" father decided on his days off we were to scrap-out the guttings from a Detroit hospital he was remodeling. A temporary construction elevator was erected on the outside of the 5-6 story building. In big plain letters on a sign on the elevator it says "NO RIDERS". So my father being who he was says, "You two are going to use this--get in".
So he tries to start the old Wisonsin gas engine that drove it and it quits. (Read: this rickety thing is on it's way to the scrap heap)
He fires it up again and says "Wait", so we don't get in. He drives it to the top, the engine quits, and it free-falls 5-6 stories. After the ground stopped shaking, we pulled our you-know-whats out of our mouths.
That was truly a "Kodak-moment" and a day I'll never forget!
Safety-schmafety. We don't need no stinking safety brakes.
Yeah. Right.
And this concludes yet another chapter of "The (mis)adventures of Jeffy" or, also known as, "Excuse me. I have to change my shorts AGAIN."

When I was rebuilding Katrina-land I partnered-up with a huge Florida-based vertical conveyor manufacturer (notice I did not say "elevator" . The Gulf Coast has some homes that may have to built up as high 38 feet, so some means of transport was necessary.
We found that:
Private "personal lifting devices" i.e elevators have to be inspected by certified elevator inspectors once a year.
"Material and cargo vertical conveyors" do not need inspections. They do not any safety devices whatsoever. Ours had double cables.
We were selling "cargo lifts" for residential use which were not governed by laws necessarily. The buyer was told they "are not allowed (wink, wink) to permit anyone to ride the lift---and sign here that you will not use it for that."
Millions of products are used everyday that do not carry UL listings.
