So a friend in NorCal has firewood, a place to keep it, & woodstoves.
But the route from B to C is circuitous. If he could lift it say 14' to the balcony.... My initial idea is a vertical steel {flag}pole, set in concrete. Say 1.5" dia. pipe. Around it slides a larger diameter cylinder; it slides up and down. A scuttle, a open U shape, is welded to the slider. {shown tipped 90 so I can use more ASCII chars...} ___ /(fw) |(fw) |================= {pipe} |(fw) \___ My first thought for lifting it was a winch at the base, with a pulley at the top; the cable goes up the center and over the pulley; al-la a sailboat mainsail sheet. But then I thought of garage door openers. One scheme has a long lead screw and a traveler that is threaded to match. If you took one and put the motor end at the top; it could pull the scuttle up. Plus openers have overload clutches and reversing built in... To slow it down, however, we'd need a long screw of finer thread, and hopefully Acme not NF. Not sure how to do that....we'd have to butt 2+ shorter rods together, weld, yet get the threads contiguous...
