Expedition Everest drop, in excess of 100ft!

[animal_king1990]

Major modifications were made to the brake systems, including the one section in the accident. Ooops! Disney however didn't consult with Intamin and Intamin even pointed that out saying Knotts would never do that (hisss!). Apparently, its common practice to inform the manufacturer of adjustments you make to a ride. In some states, like New Jersey, its illegal to made modifications without the manufacturers approval (New Jersey has the highest standards btw).

I'm more of an Intamin fan. Per Disney and Intamin together -- see Screamin'. Rode it when it opened, and many times thereafter -- much smoother than what RNR brings you (and RNR is in a climate controlled environment!

I don't buy the whole upkeep argument. Why would the amusement industry globally disregard Vekoma coasters, but pay attention to others? Bah. Build quality is build quality. You don't get a bad reputation solely based on conspiracy!

What worries me about the new Vekoma track (which is old news for RCDB watchers) is a) its new and untested at this scale and b) if Disney uses climate control to give the effect you are in a cold environment during segments of the ride -- I would imagine that fudges with the welds. During the summer, this could be a problem no?

Hmm.

Regardless -- hope to ride it as soon as it tests for the public. That way I'll experience a smooth ride.

Joy!

How do they use climate control for EE?

Basically, the interior of the mountain will feel cold, and there will probobly be snow in some areas. At least that's the way I understood it.

This knowledge is going way back to my metallurgy classes in college so I might be incorrect, but I don't the temperature difference that would be encountered in the "cold room" portion of the ride would be significant enough to cause metal fatigue in the welds. If it was the bigger issue would be frost bite for the guests if the ride was to go 101 with a train in that portion.

True. Also, temperature CHANGE is usually the culprit due to continual expansion and contraction, not a constant temperature in one location.

Its not the weld quality that I'm concerned about, its the basic expansion/contraction you get when you have temperature varriances. Welding is important to keep a track in place and not move (see Chunnel rails -- what would have happened had they not welded the track).

For example, would you think they are going to have a cold room on all night?

What about when the ride was constructed -- were certain elements of the track built during hot parts of the year, then others during a cooler part?

I'm sure Vekoma has thought of this, and if you look at joints in Barnstormer you can see they allow for tolerances. Just curious if these temperature changes a) are important and if so b) what does a coaster manufacturer design into the track to compensate for heat variances.

Expansion and contraction happens all the time day and night -- I'm not concerned about the quality of weld as I'm concerned about the effects of the Florida summer heat outside on the track, rain, the somewhat rapid cooling off through the rain, and the cold room being switched on and off throughout the week. So you have parts outside, parts inside, climate controlled.

I just think it would be interesting to see how they compensated for that if it was a problem (and no one knows this except engineers). The rest of us can guess and surmise.

I don't think the temperature differences are going to be extreme enough or happen fast enough for it to be be huge issue at least no more of an issue than what a coaster would have to experience due to normal weather changes.

As any coaster builder would...

Right... Let's keep it that way... :lol:

 

[Rotel1026]

Coaster building is not a new science, look at all the parks building coasters in the north in snow and then operating them in summer heat.

I'm going from memory here, but if I remember my CivEng welding design correctly, the welds are designed with maximum temperature variations of the connected steel taken into account. Therefore, the QUALITY of the weld is of upmost importance factor when looking at variations. The inspections look at the design requirements and check the weld to be sure they meet the requirements. As long as they are met, then the variations will not matter.

Plus, the stress created by the moving train will be much higher than temperature variance stress. The key is to design the weld for worse case temperature variation at the SAME time as the worse case stress from the train. Those two combined stresses are then used to create a stress design factor that will be used when desiging the weld.

Been a while since those classes so I may have a cloudy recollection! :lol:

It's cheaper to keep a room cold all night then to shut it off and recool in the morning.. Right?

 

[LSUxStitch]

After reading some things about the temperature change and whatnot, I was wondering about what will happen when it rains? I'm pretty sure the ride will be shut down during storms, which would put it on the same level as TT. I sure hope its not shut down more than it is open though because as all of us know, the rain storms during summer can be rather annoying lol

I would think it would follow BTM more that TT when it comes to rain. I have never really payed much attention to it but what is BTM's rain policy.

I dunno, never ride it . For some reason, that was never one of my fav. rides, I find it rather boring. (Unless you are on the back row and look back the whole time!, now that is fun)

I <3 sitting in the back row of BTM! You get whipped around a lot more back there.

The backseat is almost always the most intense seat in the train. Often, parks have different lines for people who want to sit in the front or back. Think about the airtime you can get on EE!

A 112 ft drop won't make you as sick as you think it will. I've been on larger coasters like Montu or Kumba and they don't make you that sick except theres a bit of head banging!

Nah I was j/k about the vomitting thing lol. Drops don't make me sick at all...it's the corkscrews that get me.:hurl: :hurl: :hurl: Well...going upside-down in general I guess.

Everytime I get off of Montu or Kumba I feel like my brain is splashing from side to side in my head. Dueling Dragons probably made me the most sick out of all the coasters I've been on though.
