Heavy lift ring crane - video

[Squeak]

Just some friendly advice. I worked there for 35 years and photography is strictly prohibited. From a boat or drone; hard to enforce. Your phones with cameras in them are not allowed! Of course you as a non federal employ cannot even access the area. As I said, just some friendly advice. If the shore patrol taps you on the shoulder as you are taking pictures, well, as they say; ' I tried to warn you!'

There are some limitations on photography, but they're extremely narrow (like: members of the military posting certain photos/vids taken during service to social media, photos taken of private spaces from private spaces, etc.).

Fortunately, we're free to ogle all the crane photos we want, certainly those taken in public places. Which is good news, because I went down a long rabbit hole last night researching cool cranes, and the pickins were unusually plentiful: lots of large images of unusual cranes, 50+ year-old crane photos, medieval cranes, vids, GIFs, giant crane collapses complete with interesting disaster analyses, etc. A sample:

Here we have the Chinese crane named Taisun, holder of the Guinness World Record for heaviest weight lifted by a crane - 20,1333 metric tons, in April 2008. In the photo below, Taisun is lifting a 17,000 metric ton deck box for a semi-submersible:

This exotic beauty is a climbing crane. Labeled: Brisbane, Australia.

And here's a nice short video of a crane assembly:



Etc. Plenty more where that came from.

Perhaps it is a cover but makes me wonder why the ogive-shape as a cover as the 24 story 2400 ton crane was retired in 94' and this pic appears to be from March of 2018(?)...and for sale of course as an Iconic Picture of the place from a subsidiary of the Iconic USA Today group. All news/poparozzi'a absurdity aside it seems an awfully expensive shape to manufacture for a cover. But it is a kool historical mega crane.

A quick search came up with this article on that crane at PSNS (Puget Sound Naval Shipyard) at Bremerton and will be maintained indefinitely.

Also think it might be possible from this picture to analyze the shape and size and a close approximation of the formula for the shape with a bit of creative PhotoShop, CAD work, and deduction. The high res pick I found above is 2816 x 1818 px at 96dpi.

It's a mega-cranearama. Wow - Amazing cranes...isn't that 2.2megatons...made me cough sippin' my espresso.

Here is a couple of me on a crane when We built and installed a 18 meter flag pole on top of a I think it was a 30 story building or this one could have been on the much lower 16 story both actions were about the same outcome me having to climb and walk the beam.

There is a cone in the foreground that looks vaguely familiar. Perhaps photos' of that would be considered a bit testy.

Orientation is too parallel to the camera axis; but she's the model for the cute pair at San Onofre...

Ah, yes, Le Grand Teton de San Onofre...



You just gotta know that the engineer who designed that had a wonderful sense of humor and outrage.

Serious crane-ing goin on. How do you know you're a REAL crane? It takes one or two other little brother cranes to put you together.

I'm curious; from the 0:20 mark onwards, it looks as if the column is perfectly aligned with the base. Does anyone know if it's possible to rotate that kind of load about the vertical axis, or does that orientation derive from the position of the lifting sling when it is first attached?
