jacobliford Posted August 4, 2012 Share Posted August 4, 2012 Let's say that someone is ridng Drop Tower. This cart has lifted and just released when the power goes out. What would happen? Would the ride still be able to come to a safe and complete stop? Just something I have often wondered. 1 Quote Link to comment Share on other sites More sharing options...
The Interpreter Posted August 4, 2012 Share Posted August 4, 2012 Yes. The brakes are magnetic, and the failsafe position is on. 2 Quote Link to comment Share on other sites More sharing options...

TheCrypt Posted August 4, 2012 Share Posted August 4, 2012 Even if for some reason the magnets wouldn't work due to no power, each and every ride has a backup generator to allow for the ride to run in the case of a power failure. Quote Link to comment Share on other sites More sharing options...

TheCrypt Posted August 4, 2012 Share Posted August 4, 2012 All of Action Zone, and only Action Zone, was without power. Hey, it could have happened, but I seriously doubt that only Action Zone was out of power. If another member here (hint hint) can verify wether or not Drop Tower has a generator, please say so. On another related note, I'd love to be stuck on Drop Tower! Quote Link to comment Share on other sites More sharing options...
CoasterGeek101 Posted August 4, 2012 Share Posted August 4, 2012 Yeah, each ride has a backup generator that can power it for at least a few more trains if its a coaster that needs power for the brakes, or at least 1 cycle if its a flat ride.

KI-ORIG-EMP Posted August 4, 2012 Share Posted August 4, 2012 The back up generators that the park has are for emergency use and not to power rides or attractions until power is restored. Just like if you have a back up generator at home, you use it to power your freezer, refrigerator, lights and other vital stuff. 1 Quote Link to comment Share on other sites More sharing options...
coasterfanatic83 Posted August 4, 2012 Share Posted August 4, 2012 I was in Slaughter House last year when all of the power went out in there. They just had us stay put until it came back on about a minute later.

Just like if you have a back up generator at home, you use it to power your freezer, refrigerator, lights and other vital stuff. Though I would assume that if, for example, a train was past the MCBR on any give ride, they'd use the generator long enough to get any trains that are on the track safely to a brake run.

KIfan1980 Posted August 7, 2012 Share Posted August 7, 2012 If a train is past the MCBR, then it should coast safely to the brake run - no power generation required. Any sensors required for braking should fail safe to the break condition when power goes out. 1 Quote Link to comment Share on other sites More sharing options...
TheCrypt Posted August 7, 2012 Share Posted August 7, 2012 I thought about the same thing, but what about coasters like Adventure Express or The Beast, which require electricity to the chains? Also, with rides such as Delirium, you need to raise the floors. Quote Link to comment Share on other sites More sharing options...
Mr. Christopher Posted August 7, 2012 Share Posted August 7, 2012 Brakes on coasters are designed to be fail-safe. A loss of power causes them to engage automatically. Coaster trains situated on lift hills will stop with the anti-rollback devices and are evacuated if necessary. I believe auxiliary devices such as air floors and ramps can be operated with an emergency hook-up outside of the normal air supply; backup generators assist in powering PLCs and other ride equipment for a short period of time. All rides and attractions have procedures in place in case of power failure. Redundancy is the key here. 1 Quote Link to comment Share on other sites More sharing options...

Browntggrr Posted August 7, 2012 Share Posted August 7, 2012 The anti rollbacks on coasters as well as MCBR on coasters are designed so that generators are not necessary. The last thing a park would want (does not mean can't) to do is operate a ride on generator power. This is one of the many reasons both areas of coasters are equipped with emergency exit stairs/ ladders etc. You may find some rides (i.e. sky/ lift rides, MF) that have a back-up generator. Unfortunately, these generators often fail due to lack of use which is why most rides are designed without a generator in mind and also have the ability to use a hand crank. Other rides like Giant Wheel @ CP have to be literally pushed around (20+ employees) to have all the guests exit safely: here is the trick: the guests have to be removed in a "balance" fashion or the wheel would start moving on it's own & then would have to wait until it came to a stop. Many of these emergency exit procedures were experienced in the 2003 blackout. 1 Quote Link to comment Share on other sites More sharing options...
TheCrypt Posted August 7, 2012 Share Posted August 7, 2012 Well, that's what I get for listening to the news! I remember watching a short story on 2 News, but it was awhile back. It said te park was out of power for about an hour. Anyone know what year this was? Quote Link to comment Share on other sites More sharing options...
teenageninja Posted August 7, 2012 Share Posted August 7, 2012 The park also lost power in 2010 during the 4th of July-ish timing. The rides were evacuated following evacuation procedures. As MarketingExpress stated, the rides do not have back up generators and will not complete their cycles. Coasters will stop at the next breaking area if they are on the course at the time, flat rides will stop their cycle. Delirium would swing to a stop, from there, not sure how they would evacuate. All water rides lose their pump power, so the water will drain and the flume,inner tube will stop at it's current position. Quote Link to comment Share on other sites More sharing options...

Any block brakes (not trims, I'm not sure about those) are ALWAYS "engaged" by default, in other words their resting position is closed. It takes power to open the brakes to let the train through. 1 Quote Link to comment Share on other sites More sharing options...
MarketingExpress Posted August 7, 2012 Share Posted August 7, 2012 ^You are mostly correct... I can think of at least one ride at KI that has brakes (which are not trim brakes) that remain open at all times unless engaged for an emergency (including a power outage).

Honestly, it's splitting hairs, and I'm pretty sure we all understand what was meant.One could bring up an example that the train was at the block brake, with the brakes actuating as the train is passing, then the power going out causing the brakes to be in the normal closed state. Power loss=brakes to engage. Quote Link to comment Share on other sites More sharing options...
Colonel_SoB_fan Posted August 7, 2012 Share Posted August 7, 2012 Kings Island? Jul 4th 2010 Cedar Point? Sometime in 2003 I believe Quote Link to comment Share on other sites More sharing options...
Browntggrr Posted August 7, 2012 Share Posted August 7, 2012 Cedar Point? Sometime in 2003 I believe August 14th, 2003From Wiki: At Cedar Point amusement park in Sandusky, park employees had to help guests walk down the steps of the 205-foot (60 m)-tall Magnum XL-200 roller coaster, which had stopped on the lift hill due to the blackout. Several other guests had to be helped off rides as a result of the blackout. http://en.wikipedia.org/wiki/Northeast_blackout_of_2003 1 Quote Link to comment Share on other sites More sharing options...
