I make my own overhead cranes using regular winches, so no way they meet anyone's safety requirements, but these are something I have been using in several locations for decades. Yes, eventually the brakes in the winches wear and you have to replace them, and no: the so-called pulling rating of the winches (from ANY source) are not in any way realistic. I have one in my storage shelter on my farm that is 20 x 40 that I rate at 600 Kg (1,300 lbs). It uses a 2,000 lb. ATV winch with a 2:1 block. I also have an electronic load gauge and do NOT lift something up near limit without measuring. Pick of the trolley below,. It uses a smallish 12V car battery on opposite side of trolley from winch. Works for many dozen lifts per charge. My 12YO can easily move full load pulling on the chain to the trolley. I use S6 12.5 for runways and S8 18.4 for the bridge. Trolley folded up from 1/4 A36 . Buy actual crane wheels for about $80 each (best money I ever spent) For your space, would use same runway material and stand the runways on 4 x 4 x -.188 posts. You also need some cross pieces (say 2x2 1/8) to hold runways dead parallel. Second pic is the runways (tension fabric shelter) with bridge and trolleys in place.
Here are your bridge numbers:

What is your wall height?
BTW: once you have worked with coverage from overhead bridge crane you will never be satisfied with anything less. I have an 80' 1000 lb. monorail in an radial truss shelter and it is a genuine PITA to have to do everything under centerline
