So even if Intamin had nothing to do with it, you're still comparing manufacturers? Holiday Park has had this coaster for 9 years, and Intamin's liability for the ride has LONG since past. It's practically the same thing with Xcelerator, only KBF has had that for 8 years. Is it Ron Toomer's (or Arrow's) fault that Magnum slipped through the breaks and "crashed" in 2007? Was it Schwarzkopf's fault when Mindbender killed three people? The answer to all those is a resounding "no." Once the park gets a coaster in operation, it's THEIR responsibility to maintain the ride.
Well, yes....it was partially Schwarzkopf's fault in the Mindbender accident. Maybe you should get your facts straight. The accident happen approx. 6 months after opening. The company was found partially at fault for lack of providing proper maintenance procedures, or something like that, to the park. The accident pretty much bankrupted the company because they were found to be partially at fault.
It is quote obvious from the photos that an entire rear truck assembly came off of a car in the middle of the train, and the train *probably* dragged on the track causing it to stop. Unfortunately this is not the first time this has happen on a coaster. Beyond that I would say you can't assume much until (or if) more details are released to the public.
It turned out that the Mindbender maintenance manual hadn't been translated from German. In the Xcelerator incident, it was unclear whether the cable was supposed to be inspected every six months or every month. According to one news report, Knott's asked Intamin to clarify and Intamin DIDN'T GET BACK TO THEM. Of course, when CalOSHA asked after the incident, Intamin said it was supposed to be inspected monthly.
Where does Intamin's responsibility end and the park's begin?
Knott's is going to use magnetic induction inspection every month-better than visual inspection. Mindbender gets checked thoroughly visually inspected every couple of hours.
Should these manufactuers be training maintenance crews and requiring more thorough inspections, instead of signing off?
