Quoted: Wonder what was the cause of this. Bad steel? Bad weld? Will this affect the relationship with the American company that does the fab work for B&M in the US? What is the fix. Will they just put in a new support? View Quote They should all be inspected, it's probably not the only one starting to crack. |

Carowinds is like 2 miles from my house. Neighbor showed me that video today. Scary as hell!
Failed at the top weld joint where the column tubes/pipes were coped together, then the failure propagated down the length of the weld, then the vertical column failed at the saddle low point. Looks like a fatigue failure at the top weld joint. |

Interesting loading , static is eccentric, dynamic is horizontal and appears to have caused the fracture in the fabrication . The resultant would be a little complex to figure . Maybe some thermal expansion load that wasn't figured in .

I'm a huge roller coaster fan.
90% of what I ride at amusement parks are coasters, and I find this news very unsettling. |
|
Is it possible to do some sort of ultrasound verification of welds because I suspect that every single weld needs to be verified safe.

Quoted: Is it possible to do some sort of ultrasound verification of welds because I suspect that every single weld needs to be verified safe. View Quote An inspection company needs to do an inspection of every attraction at the park as they are obviously negligent. The state should close the entire facility until inspections are complete. |

Just more white supremacy causing failure of amusement park rides.
This crack will affect people of color and members of underserved communities hardest. |

Quoted: I'm a huge roller coaster fan. 90% of what I ride at amusement parks are coasters, and I find this news very unsettling. View Quote I spent some time in my college years working third shift (cleaning crew) at a theme park. One of the coasters had been there since the park opened and was a typical old school coaster with a truss framework supporting the track. I don't recall anyone mentioning anything more than generic maintenance issues with that coaster. A newer coaster was more exciting to ride and had support columns similar to the coaster in this thread. One night, I asked my supervisor what a maintenance crew was doing on that newer coaster. "Welding cracks." It was apparently normal for them to spend a night welding cracks (on that coaster) a few times each summer. |

I was there last year and I wouldn't get on the fury. My son went around and around on his fast pass
Dont like intimidator either but you can see some nearby cities and aircraft coming into CLT atop both Fury and Intimidator. Afterburn (the one you hang from) is awesome. was about 400-500 for fast passes x2 and parking; but it's the only way I ride man, no lines. sometimes people waiting in line give you a dirty look on your 3rd go round lol |

Now that’s not a small crack. That sucker is clear through the whole thing and displaced quite a bit.
Big coasters have BIG cracks. |
|
1. Poor Design?
2. Inferior Assembly? Don't start telling me the steel was not quality material. No way. |
|
Quoted: Cracked at the weld HAZ. That cracked a while ago and the other half of the vertical fatigued rapidly due to over load. They should all be inspected, it's probably not the only one starting to crack. View Quote This is exactly correct. It can be fixed by welding it up and then I'd sleeve it just to add some extra strength, but I'd bet money there are other cracks. |

The broken column appears to be at the apex of a curve. Maybe they should have placed one at either side to take up the load.
I wonder if that column was already stressed when it was connected. |
|

I used to love amusement park rides as a kid. I went to six flags with my three boys recently, and a few of the rides scared the shit out of me. Not because of the G forces or fear of heights, but having seen how shitty/lazy maintenance people can be at their jobs.

There’s a picture circulating now that someone took on June 24th showing it having a crack starting to form on that very support column. Why nothing was done then is worrisome to me since I rode Fury 325 twice last Saturday!
|
|
On the bright side, at least people don't have to pay $250,000 for a ride.

I think the only story here is how the park missed this for days.
Things can break - I think it shows a solid design in the fact that it’s broke clean through at the apex of a turn and still didn’t end in disaster. |
|
Obviously the stress in that area exceeded capacity. Yikes. Complete failure. Wonder if failure was sudden or progressive
|
|
|
I’m not a roller coaster designer or engineer but I did want to be one as a kid. I feel like they designed this backwards. There’s nothing really supporting where the force from the track is being pushed.
