Alton Brown has a pulley setup that may work for those of us who can't or don't want to permanently attach pulleys to ceilings. In season 10, he did an episode called "Fry Turkey Fry" and built a rig off of his aluminum (I think) ladder that would accept a pulley system along with a cleat to lock the grain bag in place above the brew kettle. It seems to work well and is adjustable in position so you can make sure you don't get any swing or motion when lifting it out of the brew pot. I'd trust the set up to hold at least 40 lbs when using a sst bucket like Seven did, if your mounting is secure enough, with some decent sized bolts.
I'm going to try this method out when I do my first BIAB, but I need a fermy chamber built before this so it'll probably be a few months.
Great advice though!
I haven't finished collecting and assembling for my keggle BIAB setup yet, but I plan to make a "shelf" out of this to cover the heating element, dip tube, etc. It will serve double duty to keep the weight of grain off weaker components, and also keep the bag from direct contact with the element to prevent melting. I just haven't decided if I'm going to cut and bend the sheet into an inverted U so that it acts as a 3-sided cage, or just cut it in a circle and use SS bolts as feet to raise it to the correct height (which would look like a tall, poorly fitting false bottom).
i do BIAB and sparge. i just heat 2 gallons of water in a second pot, and after the mash is done, i pull the bag out and dunk it in the 2 gallons. Stir, wait 10 minutes, then dump those contents into the main kettle.
