Rigging fail chain reaction...

Why do we never see the end of these videos?

Cos the videographer believes in self preservation. ;)

Fail #1 , engineer of panel correctly sizing/ locating hardware to volume and dimension of concrete.
Fail #2 How do these "riggers" and "crane operators" make such a lift without seeing ALL the weight go to bear on the upper shackles and cable? There was plenty of time to clear out, or stop and lower.

PS. Seems clear shackle or cable seizing on upper right gave way first. Did that wave of energy flip lift cable off it's sheave, did the boom collapse, or hook then fail? At 15'' you see the spreader or boom tip hit the ground! Epic, catastrophic component failures.
And parts of crew don't even clear out as far possible. InTheGroove's "chain reaction" a perfect assessment.

This was in the news this morning: https://home.nzcity.co.nz/news/article.aspx?id=314830
I keep well clear of the drop zone around lifts - best laid plans of mice and men and all that.

There are preventable 'accidents', mother nature and acts of the Gods.

I write LOLER lifting plans for similarly off-centre/angled loads, that the anchor point tore out/sheared should have been allowed for as a potential failure as such side-loading is well known to cause such failures. Too many people too close is bad site management control, the pendulum effect was entirely predictable even if everything had stayed connected, I'd even bet the crane loading calc's didn't allow for the weight of the spreader beam or the 2 chain brothers.

Glad no one got hurt!

It always amazes me how people stand (or are allowed to) in dangerous places when equipment is being lifted. I do engineering consultancy in a lot of large steel plant and often see their employees walking under plates that are being lifted - not sure what they think their hard hat could contain, apart from a crumpled body. It is the old adage that familiarity breeds contempt.
I have also witnessed some nasty accidents at sites and a few deaths - all were unnecessary.

When I was a cop, I never stood around a towtruck winching a car or lifting a vehicle.
The steel cables on a tow truck under that kind of tension if they break, can turn into a deadly whip that could take someone's head right off.
We've all seen nylon tow ropes and steel chains break and go right through the back window of a truck cab.

You are correct in this case but I have watched a lot of other videos with this problem.

Looks like the guy stading on the load when it let go might have gotten pinned against the other side of the truck. No safety coordinator worth a cuss around that day!

he may be a Red Neck

Here's your sign...

Personally, I see that as the problem; reliance on someone to monitor one's actions.
As Mike Rowe [Dirty Jobs, The Way I Heard It, Returning The Favor, TED.com...] puts it, the superior perspective is Safety Third, with personal responsibility as number 1.
Expecting an observer to know more/ care more about you [and those around] than individuals, is merely a dodge by insurers, redirecting culpability to an intermediate party, and forms niche of personal injury attorneys.
With another tip of the hat to their lobbyists...

Safety co-ordinators have a role, all too often absolving management from ensuring proper training and following of company/site RAMS. This is a classic case illustrating why in the US the 'behavioural safety', blame the worker, 'industry' has taken root and is growing, as it favours employers by using poor employee behaviour's as an excuse, something as a qualified Health and Safety practitioner (UK) and Trade Union H&S rep. we've been fighting to keep out of UK law.

To quote Mao Tse Tung's "Little Red Book" of observations: "Peoples attitudes and opinions that have been formed over decades of life cannot be changed by holding a few meetings or giving a few lectures".

Toolmaker51 and NeiljohnUK have perfectly proven my point. With a good H&S person, every one of those people working there would have known instinctively what there role was and where NOT to be during that operation whether that H&S person was there or not. A good H&S person would never have let them on site without thorough, proper training first. "the superior perspective is Safety Third, with personal responsibility as number 1." That sentiment excludes training which is the true superior approach to safety. Also included in our training is the idea of respect for your coworkers and recognizing potential safety risks that might affect them. Where I work I build these in to every aspect of training along with superior risk assessment and superior preventive measures to further reduce risk. Complete ignorance of training and other "rules" is typically when we see an injury but the injured person is retrained not made the scapegoat.

And Everybody here has learnt some Serious Lessons and Hopefully Grateful they're still Alive. But Really if you've done this kind of Stuff before there should be No-One hanging around close by.Just in-case "The Golden Rule" and it is Golden.:rolleyes:
