THIS! ^^^ This is exactly what I was asking, this company's procedures seem quite good then and what I would want/expect. Now here's another question... is this mandated practice or is this just what your company chooses to do? And others (in Australia) don't all do that? As for the United States, it seems things are very unregulated and this is probably not all being followed. Thank for a thorough answer.

No what I'm saying is as an enthusiast (I was this before an employee, and to be fair I don't work in ride maintenance so I really would still think of myself as an enthusiast in that regard) I know the procedures and processes and parks have in place. It's pretty well out there as I say in the enthusiast community. I would think that equal fans of the carnival industry would also have the same knowledge so could at least comment. At this point (this is as you say speculation) I would happily take the word of someone that says they do this or don't do that, I'm not seeking documented proof. I'll give you the point that yes there may be the possibility that: the ride operator did engage the services of a reputable NDT inspection provider, have said inspections regularly carried out, was provided with the certifications of such. But in fact this reputable company was falsifying or was negligent in their inspections, OR that the ride passed all inspections which WERE don't correctly and this failure managed to manifest from non existent to catastrophic in the space of a maximum of 12 months (of course assuming the inspection was carried out at most 364 days prior to this tragic day). IF all of these things occurred then yes I will happily stand here and say, freak accident, they are in no way negligent. Not trying to be a smart ass here at all, I do enjoy the discussion, but I think you'd have to concede that what I've written above is very highly unlikely.

Ok I'm using every formatting tool that's provided to enhance my text. My opinion through this ENTIRE THREAD has been, IF they are carrying out these practices then I am happy with that, IF NOT then I have major issue. So far there is nothing to say that they ARE following these practices, EXCEPT the operator of this KMG ride who clearly wasn't doing inspections on that point of failure. So I'm not saying because I can't see it then it doesn't exist, I'm saying my view is based on whether it does or doesn't exist. As a Theme Park Fan I know can say it does happen. So far a Carnival Fan has not been able to do the same...

That paperwork was proof of a general mostly visual inspection at best. There is no manufacturer paperwork detailing major preventative maintenance regimes. There is ZERO change a show appointed on site engineer is carrying out major ride rebuilds. I'd be interested to see this WorkSafe paperwork. I work in the industry so am intimately aware of what the parks do, plug is pretty well publicised and common knowledge amongst the enthusiast community.

As I keep saying, I'm asking the question of what maintenance they do have. So far no one can answer that question.

Don't worry, I'm in no way about to defend DW on that accident, and I have my own fairly educated opinions on it also. I would in no way ride that ride if it opened tomorrow in the same state it was in the day prior to that accident either. And if I felt that accident was caused by maintenance standards then I wouldn't ride anything at DW either.

It also seems fine with old mate getting on board in Ohio and then being flung off to his death so...

I have nothing against the industry... IF... things like seats flying off rides stop happening, sadly they don't. Do the point it's almost now just accepted by the general public, no one is boycotting carnivals like they are DW now are they? I appreciate and applaud your passion for the industry @HussRainbow87 however devotion, and admiration don't equal safety and science. The lengths parks go to for ride safety is quite incredible (and hugely expensive), until any evidence of the same thing happening with in the travelling rides circuit is presented, I just can't get on board. I'm sure the manufactures do have recommendations, but are they being enforced? Certainly not in many countries, Australia I am waiting to be shown this is the case. Specifically back to this recent incident. They was clearly a major flaw there, hence the redesign, why in the hell was this thing ever allowed to operate? Maybe someone can answer this general question for me then: How long and how many people does the DAILY inspection for one of these rides take, undertaken each and every day prior to opening? Likewise how long/many for the WEEKLY inspection? We can then compare that to a park flat ride such as say, The Claw, and work out if best practice really is occurring here...

The bearing is not on whether it's safe, but on acceptable risk. If there is an equal risk in doing something because I need to in order to get to my apartment, to something that will give me 2mins of amusement. I'm more likely to accept the risk in using an elevator than riding a roller coaster aren't I? Thats why it's silly when people say "well perhaps we should stop crossing the road then" as an argument. Youll also notice I'm mostly seeking answers in my posts to educate my opinions. But instead of getting "yes manufacturers do insist on XYZ and all operators follow that and it's enforced" I'm more getting "the Jones family do a darn good job of ensuring all the light bulbs work but I can't speak for the Smith family, they can be dodgy at times" kind of responses. Park ride manufactures stipulate strict maintenance regimes which or parks follow. And in some cases parks go beyond those because manufacturer recommendations should be considered the minimum. Do the traveling ride manufactures do the same and do the operators do the same? This I don't know and nobody seems able or willing to answer. Oh and @AlexB one would hope that was sarcasm but in the context of this discussion I felt the need to point out how stupid and wrong that idea/comparison was in explicit detail.

One of your stupidest remarks ever here. 1) Coaster tracks do not have components... two all welds are certified to begin with...three the connections ARE regularly inspected...four the lattice welds of the track are not considered high stress areas. The trains on the other hand do in fact receive this. As for considering parks and traveling rides differently... why? Just because the major maintenance parks go through is too expensive and inconvenient for carnival operators? The ride mechanics and components are pretty well identical so why should one be subject to less scrutiny? Also the analogy to public transport, elevators etc is also a poor one. Those items for one are used for necessity not fun so it's not a matter of just choosing to avoid them. Also these items aren't engineered on the boarder line, they have massive safety factor to reduce the requirement for inspections. People who are carnival fans are lacking perspective in this topic.

Yeah I see a lot of XYZ maintain their rides looking great. TBH until someone comes out and tells me "regulations state that all rides have a compulsory annual tear down to component level and NDT of all critical components" I've no interest in the things. Doesnt sound like thats going to be any time soon? Also legitimate question... Does anyone know of traveling ride operators had the same procedure and maintenance audits the parks did from the government after the DW accident?

I feel if I've learnt anything from this it's in Australia not to trust these rides... and in America not to even go within a mile of them for risk of pieces falling off.

Oh that's not really a good look

Then you're doing badly

Yep my thoughts exactly.

sigh

Umm did you look at the drawings? Its a weld. It goes from plate steel to round tube. You can see the round cut out in the plate. There is every possibility that an undetected (which is easy if you never do testing) fatigue crack propogated from the welded connection up to the point of failure. As for high stress, this join takes the entire load of the seating assembly and transfers it to the main support assembly. I think even a first year apprentice can identify that as a high stress area. I squarly laid blame based on facts for the Dreamworld accident, I just didn't do so publically in the media and I'm not doing so here. Merely commenting on the facts provided. I don't blame the manufacturer, I blame the industry. And yes, I do expect a then to test every critical component and part of the ride and I'm sorry if that means it's out of action for 2 months of the year. Why? Because it's best practice and what all of our theme parks do is to keep you and everyone else safe every day. I think some people would be very surprised to learn in just how many pieces say one of Superman's trains is in right now. To ensure nothing is missed. Someone is dead, I do think "it would take too much time and be too expensive to test properly" is gonna cut it anymore than "nah we decided a sensor to stop the raft conveyor in the event of a backup was too much hassle" would.

My point is (and where the hell im getting this idea is simple good practice!) was the area that failed subjected to regular NDT intervals as standard procedure? If not then why the bloody hell not? It's a high stress critical weld for an amusement device. Every theme park ride your get on in Australia is subjected to such testing.

Yeah I agree with Skeet (holy shit!). It also sounds to exactly describe the style of joint/weld where the ride failed. Also interesting that subsequent designs added strengthening plates in that area but this did not. Also scary is it says the fix should involve magnetic NDT on the joints in question. I would have expected this would be park of regular annual maintenance anyway. If it's not just chalk it up to another reason I don't ride these death trap trailer machines that are assembled by hillbillies no offense of course

No but some highly qualified at the GCB has clearly once again been skimming parkz articles and then ripping off as their own story. As usual many innacuracies cough #journalism

I feel with all the electronics and actuators, coupled with the fact it's not painted to match anything it's definitely a jig of some sort.

Is the orange piece steel or fibreglass? If it's steel and torn like that then looks like a very serious catastrophic metal fatigue issue.

$35 million $15 mllion coaster $20 million dark ride (includes infrastructure and building construction costs) that's a start... followed up with a other $10-12 million family coaster in 2 years. That's what they need to compete IMO

Music is not available publically. Has been discussed at length

Meh those two coasters have sucked since the day they stopped dueling anyway.
