LIttle bit of a long shot, but I am in need of a manual lift with about 10' vertical lifting capability. Capacity needed is moderate - 200 or 300 pounds max. I am looking for something similar to the device pictured below. Doesn't need to be pretty and one that needs some repair is also OK. I can pick-up, pay cash, and would also be willing to trade some pallet racking.

I never bought one of these, but I have rented them, not expensive to rent buy the week. Just a thought.

for what its worth, we call them duct jacks. I usually just rent them, but they are super handy for sure.

Thanks Rowdy and DedShort! I have thought about renting one as well, but if I can't find a decent used one, I will just make one. I have quite a bit of last-in first-out pallet racking material that would work perfectly. The tracks and trollies will work great - overkill for what I need, but they will do the job.
