I like these industrial shots, process sequences. Find it interesting that you calc your cropping as focal length "Nikkor 70-200mm f/2.8 @ 340 mm." Unless you're using an extender, pretty sure you'd note this if so. <span class='jfriedl'>I was using a 1.7× extender sometimes. The "340 mm" is my way of telling you when I'm too lazy to actually write "1.7×TC". —Jeffrey</span> Nice! I like these industrial shots, process sequences.

Yeah, I've always been fascinated by marvels of engineering and functional machines like this. One minor nit: <i>"The entire weight of the platform, 60-foot jib, and three men is borne, individually, by each link in that chain"</i> Due to the 4:1 mechanical advantage of the block and tackle arrangement, each link is only holding 1/4 of the weight. Cheers, ~john <div class='jfriedl'><p>So if one link breaks, only 1/4 the crane falls? Or the whole crane falls only 1/4 the distance? Or, the men become only 1/4th dead?</p> <p>You may be <i>factually</i> correct, sure, but emotionally, <i>a whole friggin' lot!</i> divided by four is still "a whole friggin' lot!" :-) —Jeffrey</span></p></div> Love the photo sequence.

So if one link breaks, only 1/4 the crane falls? Or the whole crane falls only 1/4 the distance? Or, the men become only 1/4th dead?

You may be factually correct, sure, but emotionally, a whole friggin’ lot! divided by four is still “a whole friggin’ lot!” :-) —Jeffrey

During my 4 weeks in Japan, last year (already...:-( ) I saw much of this Crane machines. And wonder many times seing this big machine, how could they grow up. Think this one is not as big as the one I saw in Yokohama ! Thanks for your articles, it is always a pleasure for me to read them. Hello,

What a very very interesting article ! During my 4 weeks in Japan, last year (already…:-( ) I saw much of this Crane machines. And wonder many times seing this big machine, how could they grow up.

Think this one is not as big as the one I saw in Yokohama !

Thanks for your articles, it is always a pleasure for me to read them.

Loved the technical aspects, but was struck by two things: the VERY voluminous pants (They can't be jeans, can they?) the workers are wearing, which would seem somewhat unsafe to me,and the fact that they wore hardhats (a good thing) but just socks, no shoes, (not a smart thing in my eyes.) Of course I may not have observed it correctly and perhaps they are wearing special footwear, but I found it curious. How did Zak manage to keep Anthony inside while this was going on? <span class='jfriedl'>In reverse order: Gen has lots of toys. The workers' footware, <a href='http://en.wikipedia.org/wiki/Jika-tabi' rel="nofollow"><i>jikatabi</i></a>, are standard among construction workers. I'd like to get some if I could find size 32. The clothes are pretty standard too... and you can read all about them in Alice Gordenker's excellent Japan Times column in Dec 2005 when she wrote about <a href='http://search.japantimes.co.jp/cgi-bin/ek20051220wh.html' rel="nofollow">baggy trousers</a>. —Jeffy</span> Very, very interesting post!
