Intamin Question

Monday, June 17, 2002 8:44 PM
On all Intamin coasters do the lifts "speed up"? I know Millennium Force does because of the elevator lift system. SROS at dl speeds up as soon as the ride attaches to the lift. Its really cool because its totally silent. "Click, Click, Click, Click, VROOOOMMM!!!" the clicks are when the train is attaching. After that its quiet. Do the other intamins do that?

I think what your talking about on SROS would be none other that the first car starting to drop.

Not at the top of the hill. At the bottom.

Ooooooooo ok, it most likely happens once the full train is on the lift. Looking at pictures, I can see that theres a tight turn before engaging the chain. The train is probobly traveling slower when half is on the lift and half is still in that turn, becasue the chain is dragging the train throught the turn to get on the lift. Once the train is straightened out I would think the chain would be able to get going to its normal speed.

I think the motor itself goes fast becuase you not only feel it but you here the motor get louder and more powerful. I think this is because if the train goes to fast getting on the lift it may not connect properly. But as soon as its all on it speeds up. It adds a thrilling effect to the ride. My friend "Danny this thing sure goes fast!" (me) "Just wait" (lift motor) "vroom!" (my friend) "Oh no i'm gonna die!" lol He hated it. He rode predator all day and that was about it. The firsts words were "that drop was nausiating" after I informed him of the technicologically advanced magnetic brakes.

I think lift spped is also determined by the position of the previous train. If the train has not cleared a certain spot the lift is slower, as soon as the previous train clears that spot the lift speeds up.

As far as I can tell, all Intamin and B&M hypers have 2 speed lifts. A slower speed for idle and a pretty quick speed for actually lifting.

The turn is not what makes the difference because S:ROS@SFNE does the same thing.

The WWW woodie at WB Germany also goes at normal speed (which already is quite fast), but after the first half of the lift, the train is being pulled into the first drop with an even greater speed.

It adds something cool to the ride. The cablesystem on EGF and Goliath also speeds up when the whole train is on the lift.

But I really noticed when I rode my first time on SROS that as soon as the entire train was on the lift, that the lift sped up considerably. (you notice it more in the front than the back)

I guess it is just Intamin's signature.

Yeah, I rode S:ros in Darien Lake a couple of years ago, I noticed that it did speed up too. Millennium Force speeds up when you're about halfway there.

It is all in the blocks - this was going around in a thread a week or so ago - MF is all one "block" and the train on the hill goes slow until the one currently on the track reaches the brakerun. This way, if it valleys for some reason, the lift can be stopped until the problem is fixed. When the train reaches the end of the block, the lift speeds up. It's an Intamin signature, but also a very smart safety mechanism.

Most coasters do this .. Arrow, B&M, Intamin .. Even the Intamin built American Eagle, and the in-house Viper at Six Flags Great America. It's nothing special (probably energy/mechanics saver).

Not saying the reasoning is wrong, PittDesigner, but the timing certainly is.

On Mem.Day weekend, S:RoS at SFA... One train would reach the breaks and come to a complete stop on the break run while the other train was still in the station. The train in the station would dispatch (with the other train on the b.r.) Upon reaching the lift, the train would start to climb slowly, and then, not far into the lift, it would speed up considerably.

Yes, Millennium Force does not follow that pattern at all. When a train enters the final mag-brakes into the station is right about when the first train is being pulled into outerspace by the lift. It's about 2/3 of the way up when the lift kicks into high gear... long after all trains are in their new block.

Well, if the train didn't stay slow for very long, I'd say this ... the beginning of the lift is always designed to be slow. At some point partially up the hill (probably right where it picked up in your example) the computer starts checking to see if all operating trains are out of the block. If they are, it speeds up the lift. This would explain why with the other train in the brake run, it started slowly. This also would make sense for 3-train operation (not sure if thats possible on S:RoS, never seen it before) because like MF, there is almost always a train in the brake run, its the 3rd train thats the problem. Hopefully that was clear enough ... it's been a rough day at work already and its just now lunch time ... I'm fried ...

Well yes MF does follow that pattern, it has to since I've seen it that way and I've never seen a train even fully out of the station before the other is fully through the first brake run, and secondly if it wasn't for someone on here who works on MF, I wouldn't know any of this - I got the info from him and did a little investigation that confirmed.

Well, for the SRoS @ SFNE, they all have to be in the blocks to engage onto the lift, the comp won't let the train go onto the lift without the other train being on the block. I witnessed this when a ride op tried to dispatch the train before the other train was in the block, the train was completely loaded, everything, and the train just sat there for 10 seconds while the other completed the circuit.

Yes, on SRoS @ SFNE and BDK and BTR they all have energy saving lifts. This is when the chain speed slows down when the train is not on the lift. BTR has had some problems with the sensors at the top being sensative and detecting the train when it was not quite there, causing the lift to stop prematurely.

Being a regular rider of the back seat on S:RoS at SFA, I can tell you that the lift speed never picks up until the final car of the train gets onto the chain. I know that the slower chain motion is to reduce the amount of energy used by the ride and I think that the reason that it waits for the last car to engage the chain is to avoid putting too much stress on any one part of the chain...in other words, think about how much stress would get put on a small section of chain if the chain sped up as the first car engaged, that small section of chain would have to "yank" the entire car by itself....If it waits for the last car to engage, each section of the chain only "yanks" a small part of the train. I hope that explanation makes sense.

As far as anything with 3 train operation, S:RoS at SFA will never have three train operation....it doesn't have a third train....and the second train is always idling in the brake run when the next train dispatches.

Happy Coastering!
