Is that what it shows you? I just searched for that exact thing. The first two were ISO standards, the third wikipedia, and the fourth a paper on crane hook stress analysis.
Not as good as a directed search by a professional, sure (and I haven't actually looked at any of those papers, so who knows how relevant they actually are), but my experience seems a lot better than what you're implying.
- brudgers 12y agoIf you followed either of the links to ISO, you would have found that they are offerings to sell the standards. The technical information is behind a paywall. That's ISO's business model. The link to Wikipedia is about cranes in general. If a librarian said "the answer will cost you $181 (CHF 178,00)" or "here is a book about cranes" we would probably agree these high quality agree even if we might disagree over their being wrong. Nevermind that ISO standards are not necessarily a good set of design principles because minimum requirements are not the same as design tradeoffs.
