sccard01 Posted June 9, 2008 Posted June 9, 2008 this is weird, another intiamin Drop Tower accident http://www.screamscape.com/html/portaventura.htm Quote
Thrill_Biscuit Posted June 9, 2008 Posted June 9, 2008 I'm glad this one didn't end tragically. Quote
TH13TEEN Posted June 9, 2008 Posted June 9, 2008 ^ Me too speach less. I wonder if KI is going to do anything? http://www.rideaccidents.com/ Quote
Coasterkidman Posted June 9, 2008 Posted June 9, 2008 Jesus. I'm Glad no one was hurt. I think Intamin should really take notice here. Quote
sccard01 Posted June 9, 2008 Author Posted June 9, 2008 After the Six Flags Kentucky Kingdom accident, I'm sure this park had tighten the maintenance on this ride. What if their something wrong with all Drop Tower rides/cables? Quote
Coasterkidman Posted June 9, 2008 Posted June 9, 2008 What type of Drop Ride was this? The SFKK one I think was a G2, and Drop Tower @ KI is a G3. Quote
WooferBearATL Posted June 9, 2008 Posted June 9, 2008 Well as horrible as this could have been, the fact that this has happened again bodes well for Six Flags. Quote
Kawana Posted June 10, 2008 Posted June 10, 2008 What is going on with these drop rides? Is it an effect of wear and tear, or is it a design flaw? Quote
KIBeast Posted June 10, 2008 Posted June 10, 2008 Over at coasterbuzz, Dave Althoff may have an explanation about the cable problems. As many of you may know, Dave knows his stuff. Here's what he had to say about the situation. This stems from a conversation he had with a former controls guy for Paramount, for an aerial tramway manufacturer, and for Arrow Dynamics. He was also very familiar with Intamin. Anyway, if we go back to the findings from the KDA report on the Kentucky Kingdom mishap, the major issue there was that the rope was lacking in lubrication, which was probably part of the reason it deteriorated quickly to the point of failure. What Kevin notes is that there was apparently a mechanical problem with the ride (rope slippage) that Intamin did not adequately address, which probably resulted in the maltreatment of the ride components which led to their ultimate failure. It would be interesting to find out if Port Aventura was also having cable slippage problems and addressed them in a similar fashion...by removing the lubrication from the hoist ropes. --Dave Althoff, Jr. Quote
MarketingExpress Posted June 10, 2008 Posted June 10, 2008 Kudos to the rides crew for noticing what what going on and taking immediate action. Quote
Phantom Theater Posted June 10, 2008 Posted June 10, 2008 Kudos to the rides crew for noticing what what going on and taking immediate action. Same here! Quote
Browntggrr Posted June 10, 2008 Posted June 10, 2008 Well as horrible as this could have been, the fact that this has happened again bodes well for Six Flags. From one angle, I agree, as long as the ride is indentical to the former S;ToP. But from the other; since the accident in Spain did not end tragically, quite possibly due to the ride operator hitting the E-Stop button, that could be against SF and their training procedures.

Yes, but the fact that there was another incident will give SF's arguing points that there may be some inherent issues with the design and operation of the ride. Quote
The Interpreter Posted June 10, 2008 Posted June 10, 2008 The rides are not identical. The Six Flags Kentucky Kingdom ride was a prototype. Quote
Browntggrr Posted June 10, 2008 Posted June 10, 2008 Given that information, it may not work out for SF the way they would hope it would. But from a training aspect, that could make things worse for SF. They really need to settle this ASAP. Quote
sccard01 Posted June 11, 2008 Author Posted June 11, 2008 THIS Drop Tower IS ABOUT 70 FEET TALLER THEN THE HELAVATOR ALSO THIS Drop Tower GOES UP AT A SLOWER PACE THEN THE HELAVATOR Quote
shadow2k3 Posted June 11, 2008 Posted June 11, 2008 Because caps lock is cruise control for cool. Quote
Guest rcfreak339 Posted June 11, 2008 Posted June 11, 2008 If my sight is correct this Drop Tower is a stand up, couldn't this accident have taken a whole leg if the ES wasn't pressed it could have been much worse then the SPTOP accident. Quote
The Interpreter Posted June 11, 2008 Posted June 11, 2008 It would all depend on where the cable hit...the Superman: Tower of Power incident at Kentucky Kingdom could have been far, far worse than it was...or not as bad....depending on where the cable contacted the riders. It appears it would not have happened at all had someone just hit the E-stop. Quote
The Interpreter Posted June 11, 2008 Posted June 11, 2008 One issue in the Six Flags Kentucky case is where the cables came from. INTAMIN has hinted around that replacement parts were used that did not come from it... Quote
Cormaster Posted June 12, 2008 Posted June 12, 2008 i noticed Six Flags KK removed the old hellavator this year. Probably a good call. Anyway I went on Drop Tower during my last visit to KI and I was scared to death because of the KK incident. This is the last straw for me, I don't think I'm going to get on one ever again. Intamin Drop Towers are proving just to be too unreliable! Quote
Browntggrr Posted June 12, 2008 Posted June 12, 2008 ^ Hey if you feel that way, nobody is going to change your mind. But somethings to keep in mind: Both Intamin drop ride incidents were on rides that were engineered and designed before Drop Tower and are very different from KI's version. The SFKK incident was caused from poor preventive maintenance and not from a design failure of the ride itself. If the cables would have been replaced in a timely manner we would not be talking about this at all. Quote
The Interpreter Posted June 12, 2008 Posted June 12, 2008 Actually, from what I am hearing and reading, lubrication, not replacement, is the primary issue with the cables. And operation of the E-Stop button, or lack thereof, is also a primary factor... Quote
Browntggrr Posted June 12, 2008 Posted June 12, 2008 ^ You are absolutely correct that is what has been mentioned about the lubrication. But, if the cable was frayed due to lack of lubrication, it should have been noticed that replacement was necessary. Or if the cable has not been replaced in quite some time (i.e. MF elevator lift), or if the incorrect cable and/ or supplier was not used, any amount of lubrication still may not have prevented the accident.

KIBeast Posted June 12, 2008 Posted June 12, 2008 Here's a link to the KDA report, appendix 34. KDA Report This particular section discusses the condition of the rope and possible cause of rope failure. Dave Althoff, Jr. is the original poster of the link from CB. Quote
Zorba Posted June 12, 2008 Posted June 12, 2008 Is there any requirement on replacing these cables after a certain period of time? I know on mobile rock walls they cables have to be changed once a year, regardless of their condition. They instituted the rule after some cables snapped from metal fatigue where the rope attached to the coupling. I know lack of lubrication was a contributing factor at SFKK but mandating a replacement interval accounts for miss use and neglect. It screws the places that stay on top of maintenance, but so many places don't it might be justified. Quote
