    What a Dad! That piece of genuine Americana was built straight from the soul. If it was indeed built in the states? Nevertheless the build is something that came from the soul of an operator or relation to an operator of one of these amazing machines. One has to have a pair of platinums to just make it to the controls. I worked in those heights and the first time feeling the "SWAY" was a WTF moment for me. Took a good while just to pry the shorts out from between my butt cheeks. Many feet one way and then off we go the other way and so on it continues as long as the wind likes. I even had a new guy try to literally climb over top of me to get back down. Small ladder, Tight cage, freaked out new guy who swore he was OK on the way up a few times. All he could think of was going down. I finally convinced him we were both going down and there was no way in hell I was going to let him go alone.

    So imagine those operators in those cranes lifting those loads all day long that others are slinging for him and he has to magicly safely swing it over a work site teaming with ant like people. What a Dad!

    Nice Gif of the earlier video. Condenses the finer points of the build down to 38 seconds
    Never try to tell me it can't be done
    When I have to paint I use KBS products

    I don't recall which port, but used to see one of these operated by the Navy, maybe in each location. Picture above barely shows the sheer immensity...But a bit of scale can be drawn from the tires used as fenders along the side. Car or truck size, can't tell but you get the idea. Seems like draft looked about 8 or 10' deep. I suspect self powered floating cranes, like tug boats, are far deeper.
    Sincerely,

    So many additional factors come into play when lifting with a floating crane.

    NASA's Mate-Demate Device, a specialty crane used to lift a space shuttle orbiter onto a modified 747 for transport.



    One wonders if this specific warning was added after an unfortunate mistake:

    I am hoping that notice was more a product the sense of humor of the people who designed and built that amazing system.
