I have the following chain hoist setup in my garage.
A cheap chinese 2 ton rated manual chain hoist.
It is hanging on a 2" about 5/16 thick T beam that spans three joists
in the garage ceiling. It is attached to these three joists with six
5/16" lag screws, two for each joist. It is about 5 feet away from a
wall that supports these joists. The joists are spaced 16" apart. When
I screwed the lag bolts, I drilled pilot holes for them with a 3/16"
drill bit. None of these bolts was overstressed during screwing in.
Now, I am not asking for what is the maximum weight after which the
ceiling will buckle. What I am asking is what is a conservative weight
under which it would be extremely unlikely to buckle.
Specifically, would it be able to handle 700-1000 lbs?
