At my last employer, we had several freight elevators that lifted about 14'. They had large hydraulic cylinders, pulleys, and cables. They were basically two-post lifts with 10' wide by 6' deep tables. The cables and pulleys were in a reverse orientation, so that a 5' cylinder would pull 15' of cable. While that cut the cylinder lift capacity by 2/3, I think the cylinders were rated at 20,000 pounds, so the elevator had about 6000# lift capacity. NO RIDERS! signs were prominent. :laughing:

Area of a circle is pii X the radius squared.
For a 1.5" diameter rod, that's 8' long:
.75" x .75" X 3.14 X 96" = 170 cubic inches.
There's 231 cubic inches in a gallon.
231 = 0.74 gallons, or, about 3 quarts.
Therefore, a 1.5" rod at 8' long would displace only about 3 quarts of fluid.
No matter what diameter bore you use, if the rod is 1.5", that measurement never changes.
As you extend the cylinder, the fluid moves from the rod end to the reservoir and at the same time fluid moves from the reservoir through the pump, to the piston side of the cylinder. At full extension, your reservoir would be 3 quarts down. At full retraction, it would go back to full. A typical log splitter could power this with no problem.
My PT425 has a 10 gallon reservoir and a 2500psi pump. I'd be fine working that load as needed.
Keep in mind eventually it'll be the only way to go between floors, so hooking a tractor up every time I wanted to go up would be a bit impractical. Also I can't damage the floor as I have a truckload of pex in the floors.
Finished installing the support plates under hte floor joists. Wish I had thought about that before hand. Pipe clamps compressed the 3 top plates so I could squeeze them in. Even so I had to hammer most of them with it compressed. I'm glad that's done and out of the way.

That's the only way between floors? An elevator? Not even a pull-down stairway?
Nope. That's why I wanted it to be 12v battery opperated with battery a battery tender on it. 2 deep cycle batteries keeping it charged so I don't get stuck on the seocnd floor in the event of power outage. I suppose I could made an escape hatch that would let me get down between 2 joists. The workshop area will have an 8' ceiling over it, so it would only be a 3.5' drop from the first floor to the platform over the workshop that would primarily be used for storage. But for that to be viable, i'd better not gain any more weight, those 16" on center joists are pretty close together.

Oh, I guess I missed or forgot about you eliminating the stairs in your sketch in your post #25.
If it were me I'd be real concerned about "Murphy's Law" and being stuck on the second floor without an additional way down (unless I had beer and food).
I would consider installing a fixed vertical ladder to the second floor secured to the interior first floor wall maybe in a corner with a hinged hatch on the second floor?
Or maybe a fireman's pole to exit the second floor, or an opening window in the second floor wall with and emergency fire escape type chain ladder stored near the inside of the window.
Just a thought, I'm sure you will do what works for you,

Since floor space is so critical, I would build stairs outside the building.
