DJeXeL Posted June 23, 2012 Share Posted June 23, 2012 Those devices keep the anti-rollbacks and chain dogs On the underside of the train from puncturing the drive tires. Link to comment Share on other sites More sharing options...
adrielege Posted June 24, 2012 Author Share Posted June 24, 2012 Ok, so many thanks. And why does it have a cleft? I mean, the hole which is across the piece Link to comment Share on other sites More sharing options...
coasterlover420 Posted June 24, 2012 Share Posted June 24, 2012 There are two mechanisms to carry the train up the lift: The chain dog that sits inside the chain that actually pulls the train, and the anti-rollback dog which creates the clack-clack-clack...they are on the left and right side of that slide respectively, so there's really no need for the middle.

adrielege Posted June 24, 2012 Author Share Posted June 24, 2012 Yes, i know it, but my question is why it have a cleft instead of beeing a simple piece? Link to comment Share on other sites More sharing options...
coasterlover420 Posted June 24, 2012 Share Posted June 24, 2012 Cheaper? Link to comment Share on other sites More sharing options...
Tanks4me05 Posted June 24, 2012 Share Posted June 24, 2012 ^Actually it would be a little bit more expensive because of the labor required in milling out the center, assuming it's one solid piece. I don't know why it wouldn't just be a solid surface on top either. My first guess would be to align the chain dog properly, but that's what the wheel assembly does. *Looks at it again.* DJeXel: Are you sure that's their use? Because the tires are aligned a little to the left of both the chain and the anti rollbacks, thus meaning that the chain dog would be to the right, thus not puncturing the tires.

KDCOASTERFAN Posted June 24, 2012 Share Posted June 24, 2012 Actually when the chaindog engages the lift chain it's then being pusehd,rather than pulled by the chain. Link to comment Share on other sites More sharing options...
Topdrag Posted June 25, 2012 Share Posted June 25, 2012 You guys are right about them being used to keep the chain dog and anti-rollback devices from puncturing the drive tires but really it’s to help guide them over the tire better. Less severe of a jolt to them having those in place than the tire itself hitting them full force. The reason there is a cleft is because as you can see the two sides have some bolt holes. Those pieces are replaceable since they take a lot of wear and tear from the metal rubbing on them. So they have to be replaceable. So they are bolted on. The metal plate under it is completely flat. They don’t have to mill that down at all which keeps cost as as well as maintenance costs down. Link to comment Share on other sites More sharing options...
adrielege Posted June 25, 2012 Author Share Posted June 25, 2012 Ok, many thanks to everyone. Now it´s quite easy to understand the anti-rollback and chaindog device I also have other question: as you can see in this video, Dragon Khan, in port aventura, has small leds. My question is: how can they get the electricity? http://www.pa-community.com/veronika/blog/dragon-khan-con-luces-video/0ae06fbdc51baaf71a Does anyone have a picture of that device?

Tanks4me05 Posted June 25, 2012 Share Posted June 25, 2012 ^Moving a magnet through a coil of electrically conductive wiring creates a voltage. (Or moving a coil around a magnet.) The wheels provide the movement, and there are probably copper wires attached to the wheel that rotate around a magnet. The wires are connected to a circuit that sends the electricity to the LEDs and lights them up. Link to comment Share on other sites More sharing options...
TheStig Posted June 25, 2012 Share Posted June 25, 2012 ^Very highly doubt that. Probably a simple onboard battery (or capacitor) and is charged by a buss bar in the station. Many rides with onboard electronics are powered this way, if not all. Link to comment Share on other sites More sharing options...
Coasterbp Posted June 25, 2012 Share Posted June 25, 2012 Probably not using any sort of generator in the wheels to power the LEDs. Typically, there are batteries (or a capacitor bank) located in the zero car that get charged at the load/unload area. The Hulk Coaster at IOA used to have small strobes throughout the train. They looked awesome at night. And HRRR has an incredible LED display as well on its trains. Here's a link to the company that was responsible for the onboard audio/lighting.

adrielege Posted June 25, 2012 Author Share Posted June 25, 2012 It probably would be by using a type of generator, but I think that dragon khan, is in the other way ^Very highly doubt that. Probably a simple onboard battery (or capacitor) and is charged by a buss bar in the station. Many rides with onboard electronics are powered this way, if not all. .But, my question now: where is located that device: i had rode DK several times?, and i dont't see the buss bar.. located in the zero car Is the zero car this?

spinning man Posted June 25, 2012 Share Posted June 25, 2012 ^Yes. The very first part of that train is the zero car, as you highlighted. Link to comment Share on other sites More sharing options...
adrielege Posted June 25, 2012 Author Share Posted June 25, 2012 (edited) ^Yes. The very first part of that train is the zero car, as you highlighted. ok, so the bus bar device is located under the zero car, isn't it?

Many rides with onboard electronics are powered this way, if not all. Oh. Duh. I over-think stuff like that. I was probably thinking of those new LED wheels from Maurer Soehne that light up more intensely the faster the wheels rotate. Link to comment Share on other sites More sharing options...
DJeXeL Posted June 25, 2012 Share Posted June 25, 2012 ^^Yes there is most likely a buss-bar in the station that charges the batteries/capacitors while train is loading/unloading. Since they are most likely LED bulbs, they will have extremely low power consumption so a battery will be able to run them for an entire operating day without a charge.

adrielege Posted June 25, 2012 Author Share Posted June 25, 2012 Many thanks to everyone. Do you have a picture of that bus bar? Also I have another question: In B&M sitting coasters, (Dragon Khan, Kumba, Wildfire...) how does the restraint mechanism work? Link to comment Share on other sites More sharing options...
KDCOASTERFAN Posted June 26, 2012 Share Posted June 26, 2012 Hi everyone! I'm new in this forum! I'm a roller coaster fanatic, since 2010, when I ride El Jaguar, in Isla Mágica, Spain (yes, I'm Spanish)I will ask you a lot of question, sorry if I became a bit boring! My first question is about B&M coasters: - What's that? http://imageshack.us/photo/my-images/215/sinttuloep.jpg/ (in red) - Does anyone have a picture of the lift motor on a sitting multiloop coaster (Kumba, Dragon Khan) The area highlighted in red on the leftside of the pic is just the "crap catcher" used to keep loose items from falling under the ride while the top right arrow seems to be pointing to the track connector plate which has that little recessed groove in the tie which is standard on most B&M coasters.

adrielege Posted October 30, 2012 Author Share Posted October 30, 2012 Why Dragon Khan made that sound in the loop, i mean: 0:27 I sounds like "paaam" Link to comment Share on other sites More sharing options...
Tanks4me05 Posted October 30, 2012 Share Posted October 30, 2012 Hmmmmmmm... that's actually very interesting. My first thought would be the anti rollback and/or chain dog being pushed back down after experiencing airtime, but that's more of a clank sound, not a continuous roar like that.

Ithough the same, but I think that isn't the correct answer, I mean, it sounds like the colission beetwen the rails and the wheels...
