what is the standard FOS of the bolt used in the jib crane, lifting hoist system?
I don't actually know the standards for a jib crane, but I have to respond to the first answer. 1.2 to 1.5 for a crane?! maybe if you remove the decimal point from that, though really, 12 to 15 would probably be uneconomical, still If I could afford 10 I'd be tempted to use it (but I'm a coward), certainly not less than 4 in any case.
