Lift hill and launch question

This is a potentially stupid question, but I am tired of wondering so here goes:

Is there a launch on the lift hill? I have read that there are 2 launches on the ride (obviously there's the mid-launch in the tunnel), but "lift hill" to me says that the train is "lifted" up the hill, not launched. Before the announcement everyone was talking about a LIM lift hill, but I thought that was similar to the MF lift hill - am I totally wrong? On the POV animation it does seem like the train moves up the hill at a somewhat fast pace, but is this really a launch?

Thanks.

It is an LSM lift hill... the same motors that propel the launch as well. However the lift will be much slower than the launch, however from what I hear, faster than a traditional or cable lift (20-30 mph)

^Josh got it before me, but if you need to read it again, my post will do. :)

The lift hill is powered by LSM motors at a slow speed. When I say slow I mean less than 20mph. Maverick's lift seems rather fast, maybe faster than MF even. The tunnel will also use the same type of LSM motors, but will launch the train out at 70mph. *** Edited 9/8/2006 7:09:47 PM UTC by Gomez***

^ I love simultaneous posting.

Gotcha. Thanks Josh and Gomez!

I wonder how E-Stops on the lift hill will work on this kind of coaster...

If you can jog a coaster back and forth using LIMs / LSMs, I imagine they can use them to bring them to a stop as well... Stopping on a Dime, Im not sure, but I think they can stop a train with them.

Are there any anti-roll back devices on the lift hill? I didn't see any on the POV...so what prevents the train from sliding back down the lift during a power-outtage?

California Screamin', a ride that uses a very similar method of a lift system, has brakes running the entire length of the lift. One thing to note is that CS uses clamping brakes, and on Maverick's stats page, it says non touch brakes. So, I really it is still a mystery at this point. Maybe email T&T or use the feedback page on CP's website and they might mention it in the coming weeks/months. We still have almost 230 days left of construction; we need something to wonder about in the offseason.

In one of the videos or something on Maverick's page, it says that the LSMs work as brakes too. Actually, now that I think about it, Intamin said that in their write-up. That's why Intamin thinks LSMs are going to be the wave of the future when it comes to rides. Basically, the same wave that magnetic brakes are.

So, I'm guessing the lift hill will ONLY have the LSMs up the center.

Quoted from funworldmagazine.com: “Each has its advantages and disadvantages,” explains Kernacs. “The LSM coaster is a more complex design and requires more sensitive sensors, but it produces twice the force as the LIM for the same amount of energy, and you don’t need brakes because the LSM system acts as the brakes. The LIM is easier to design and maintain, but it only produces half the torque, and you must have an anti-rollback system because the LIMs will not brake. Eventually, I believe the LSM coasters will be favored over LIM coasters because of their higher efficiency.”

i want some LSM brake pads for my car.

To my knowledge Mf's elevator lift is 15 mph which pulls up rather fast. If its going to be considered to be a launch i would think it would have at least 20 mph or a little more.

The lift hill is NOT considered a launch. Only the tunnel is considered a launch.

No, on Cedar Point's website, the lifthill is cited as a launch.

I can't find where it actually says the lift hill is infact a launch. But, it does say there are two launch sections, so you may be right. If so, that would be tight as h3ll!!!

I have a question while this topic is here. What does LSM and LIM actually stand for? I know what how they work, I'm just not sure what they stand for? To Answer your question guys, to me it seems like the launch will be like 20 mph and from there the train picks up more speed to reach the 57 mph hour that it's suppossed to achieve.

(don't kill me on the spelling)

LSM - Linear synchronis motor - Magnetics all pushing in same direction. (Is this why that also act as an anti-rollback?)

LIM - Linear Induction Motor - Magnetics pushing and pulling in sequence to propell you.

If that's not technical enough. I'm not your man. You could try google or wikipedia.

^Whoops. You got it backwards.

Other than that, you're correct :).

Where's Dave at? He'd be able to give us a full thesis on the topic.

I'm rusty with my physics...errr...never understood it. Given we know the drop height and final speed of the first drop, can anyone figure out the initial speed of the lift?
