Bridge Girder Erection Mega Machine
An evening pause: More proof that modern engineering can make almost anything seem easy.
Hat tip Phill Oltmann.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
Thats an awful big and complex machine, way up high, and a lot of guys all depending that nothing fails, like the grade of concrete being poured in those columns by some Chinese contractor. Its cool, but it makes me nervous.
Look on the bright side: if it doesn’t collapse during the erection, you’d feel safe driving a car over it when it’s done.
It would be even cooler if they could do this on a curved section.
Not a safety harness in sight. Here in BC the authorities would poop nukes. Send in the grief counsellors.
I agree about the safety measures. One thing I’ve noticed about Chinese construction practices is that little attention is paid to worker safety. But when you’ve got 2 billion people to choose from, and the State protects you from liability, why worry? On the other hand, I was looking at the process from a continuous feed standpoint, sort of like a TBM.
