Frank would know what these guys are doing, but my lack of experience, seeing there's a mobile crane erected inside the building, and there's an overhead bridge crane with power drive in both axis. I'm guessing they were share lifting some part, that appears to be some part that is being flipped, and the rigging did not fail, but the axle to the gear that drives the overhead bridge crane sheared off, and that's the noise of click before "what was that?" then Oh-Oh and seeing that whole rolling crane hoist cradle rolling back and forth from the airborn and moving load.
But I'm guessing that it was that gear drive failure.
It does not appear the gas turbine case was damaged, and I like the comment at the end "we're here for another month". That poor crane operator, both the portable truck guy, and the one in the overhead bridge crane, will have some OSHA interrogations to live through, and all the safety training of everyone that witnessed this.
These gentlemen need to learn what a centre of gravity is. I think the rigging did it's job just fine. It's the brain cells that didn't work right.
I wonder if something failed on the overhead crane that allow it to traverse unexpectedly? you can see it fly across the beams like it is out of control.

I don't think there was any malfunction/failure on either crane, my belief is that it was rigged wrong if they were trying to flip it.Quote:
