Alton Brown, what the hell are you frying that requires that much of an apparatus? That's overkill for frying a turkey if you ask me.
Sure, I use a ladder as an A-frame when I'm frying turkeys. But a big turkey only weighs ~20lbs. I put a nylon rope over the top rung of the ladder and use it as a simple pulley. I tie the rope off on another rung.
I'm planning on using the same A-frame ladder this weekend when I test out my new BIAB-keggle setup. I'm using 13lbs of grain for a 5 gallon brew.
This is more appropriate for a BIAB, especially a big BIAB brew. It's heavier and you want to hang your bag for a while to let it drain. You don't hang your turkey above the pot for 30 minutes to let it drain after it fries.
