Loads Factors to apply to aircraft components for fuselage hoisting operations
Loads Factors to apply to aircraft components for fuselage hoisting operations
(OP)
Hello Everyone, been a long time reader of eng-tips, and just joined to post my first question. :)
I wanted to know if anyone has a good reference document they could point me to that has recommendations for load factors to use on aircraft components (not the tooling) for a fuselage hoisting operation. Currently I've looked at Bruhn and Niu and couldn't find anything in those texts. I have read through NASA SP-8077 "Transportation and Handling Loads" and couldn't find much there either for hoisting. Thanks

Currently, I'm planning on using a safety factor of 2 on ultimate. I was hoping to reference a document.
I'm curious about deriving a hard number of the lifting motors, how do I go about doing that, ( once again this is for aircraft structure and not the tooling). thanks

There may be a work safety requirement, particularly if the lift is high enough that someone could get underneath (inspite of placards).

Sparweb the S.F. of 2 on ultimate that I'm planning to use is based on the 14 CFR 25.519 for jacking and tie-down. thanks

apologies for repeating it, but there are probably other factors to be applied (health and safety law, or your own factory design guidelines).
hoisting inside the factory is not covered by FAR.

Good point! Elevated loads in a workplace are covered by worker safety regulation. This varies a lot because it is local jurisdictions (states, provinces, territories, federal governments) that make different rules for themselves.
