Looks like someone didn’t do any calculations before lifting!

If you do end up in a situation where you’re lowering the boom and feel the crane tipping, yank that boom back up. The closer you are to horizontal, the farther out your center of gravity and the less you can hold without tipping over. It’s exactly like trying to pick up a 50 pound weight with a fully outstretched arm vs. lifting straight up with a nearly vertical arm.

A lot of the crane tip videos seem to involve not only weight out beyond lifting points, but also some degree of lateral shift, like in that video the load is at a diagonal to the boom.

Exactly how much does the side-to-side add to the tipping factor?I know extended loads are multiplicative, but what are the ratings on off-centered loads?

Quick napkin math says after a 7 story free fall (~23 meters) you'd be going about 70kph, which is just this side of 'rough but survivable' with what amounts to a head on collision like that.

I gotta say, the plan to use the other car as extra crumble zone was good but execution was poor.

Well, now I'm curious. At first I thought it was what used to be 212 westbound (a 6-7% grade hill around a bend) but that's the wrong direction if he was heading to Eagan.

The steep part of Chesnut/41 is what he called Chaska hill. That part that has a slight little curve to it. This was before 312/212 was a thing. It's not really that steep but it's steeper than you think. He was heading for 5 to head east towards Eagan.

The load going diagonal is not supposed to happen and will completely gently caress up any calculations you did. You want to have all of your rigging positioned relative to the center of gravity of the load to ensure that it's stable and centered when lifted and optionally have lines for people on the ground to pull it in the right direction in case it starts twisting. In cases of extreme weights, you can lift with multiple cranes but you're not supposed to let either crane reach over 75% of its net capacity in that case. Cranes also have greater capacity in certain quadrants depending on their configuration and how level they are. Suddenly applying the swing brake, dragging the load on the ground, or operating when not level can all apply sideways force to the boom.

The whole reason we have a certification requirement now is because operating a crane in a way that's 100% guaranteed to never have an accident is really hard. There's a ton of factors involved and a lot of math on the part of the operator and the riggers and lift planners who actually calculate how to safely lift the load and rig it up.

It's hard to judge who's to blame on this one but you'll notice that the crane isn't doing anything but slowly lowering it to the ground. While it does stabilize a little when the wall touches the ground, the wall just keeps falling regardless of the boom trying to keep it up. That means that section of wall was absolutely way too heavy for the crane to be hoisting at that boom length and angle. They probably rigged up the top to the crane while it was flat on the ground to have it lift from horizontal before placing it and the load would partially support itself while it was on the ground, but once the crane had to support 100% of the weight it was too much. When the crane started tipping and the bottom of the wall hit the ground, inertia kept it going.

Man lifts are fun and a completely different thing. They basically are a paternoster without an enclosing shaft.

The real pictures of man engines make them seem less intimidating than the illustration everyone posts. More like a ladder rung that raises you up to meet the next rung halfway, and less super Mario obstacle. Still needs more coordination than a man lifts which you just grab and go.

E. Man engines went away but I think were temporarily revived for those old timey fun houses that were an excuse to grab people's rear end.

Which you know isn't too far from those trampoline places that have come around, which are places you can go to grab people's rear end and dislocate your shoulder.

There was an episode of Expedition Unknown where Josh Gates went into a centuries old mine to find a mineral that might have been used by Vikings as a sunstone and when they get to the centuries old man engine made from centuries old wood and going going down a bottomless abyss he asks what happens if he misses a platform.

Where I would not want to be: anywhere near an anchor being let go.

https://www.youtube.com/watch?v=b7pRfix_sNg

Apparently anchor chains aren't actually attached to ships and there's usually only a hand-operated braking mechanism that prevents the entire thing from just violently throwing itself overboard (As the video shows).

Another one which shows the end of the chain whipping the mechanism on the way out:

The red thing in front of the windlass in the second video is used to hold the chain when it is not being lowered or raised.

They're attached, but not in a way that can handle an accelerating and out of control chain. Nothing reasonable could stop those fails. The massive brakes failed, caught fire, and the anchor went into kinetic runaway. Which is what everyone in either of those videos should have done. :v:

Nothing will be done about climate change or boosting funding to fire services, they just had budget cuts this year.

So much so that volunteer fire fighters are having to pay for diesel themselves as the fire service fuel cards have run out of money.

Fire season normally doesnt really kick off until Jan when everything has had a month or three of summer to dry out. It'll get worse for the state and the rest of the country soon enough.

Even more fun thing: the company running the tours won an award for Safest Place to Work (small business category) NZ last year https://www.stuff.co.nz/waikato-times/news/118090485/white-island-tours-crowned-with-health-and-safety-award-12-months-ago . Based on, I guess, their focus on people wearing closed toed shoes while touring the crater of a constantly erupting active volcano.

To add to this I heard today that GNS (The agency responsible for monitoring volcanoes and earthquakes etc here) had pulled their staff from the island due to the increased activity. You would think that when the volcanologists are moving away from the active volcano you would think twice before taking a tour group to the crater. The injuries are sounding quite horrific as well with many with severe burns inside their throats/lungs.
