I want to hang this pulley system in my garage (partially pictured above) and probably will be loading it up somewhere between 100-200 lbs of plate weights:
What is my best option? Putting a 2x4 across multiple trusses with lag screws and hanging from that? Doubling up some studs and building out some kind of arm support system? Some other option I am not aware of? I am not familiar with how much additional weight (beyond keeping the roof up) either of these two options can support and don’t want to cause any kind of structural damage, to the garage or myself! Thank you.
