Millenium Force's Rollback

Tuesday, June 7, 2005 6:12 PM
How does it work? where is the chain dog for the cable lift and where are the anti rollback dogs?

I've never heard of that happening.

Crashmando, I think you missread the question. In the topic he should have said Anti-Rollback.

Millennium Force has a anti rollback system like any other coaster. THe only difference if that the 'dogs' don't bump along the anti rollback 'track'. When the train moves forward, a magnetic force pulls the dogs up under the car so theres no clicking noise. If the ride were ever to move backwards for whatever reason, the magnets work in reverse and thus drop the dogs into the anti rollback grooves.

I know this is a vague description, maybe rideman or someone else can explain it better.

The same concept is true for Intamin's other steel hyper coasters as well like Superman ROS.

i was on it last week and it stopped it seemed to have some kind of mechanism that slows the cable lift first. The train does go back a bit. It then catches on something within the track. That it what it seemed like to me.

Then again the ops were stopping it because some ass took his seatbelt off while we were going up. So for that it could be different. However Cedar Point Maintenence was quick to arrive and they then threw the perp outta the park. The funny thing was that a bunch of guys in line were chanting buckle up as he as by the photo shop area. Great job by the ops and also the fact that the guys werent mad but busting him some good times. *** Edited 6/8/2005 3:30:58 AM UTC by MagnunBarrel***

LOL, I joked with the op about getting a rollback on Force. Before he realized who he was dealing with ;), he said "that happens on Dragster, not this coaster". I shouldn't have played around. We ended up getting stuck on the lift for about 15 minutes.

In all my visits to CP I have only seen MF break down one time. It got stuck on the lift for about 15 minutes. No big deal. Ran 3 empty trains, and then back to regular operation.

Ride of Steel covered it. Rideman can probably explain it the best. I am not as technical as a lot of these enthusiests are on this board. ;)

While it's no secret TTD has many rollbacks, I have seen Millennium Force not make it over the 180-ft hill going to the island. I believe this was during a morning test run on the first Thursday the ride was open to the public.

I don't know if it was the first Thursday, but MF did valley out early on when sent for a morning test run on a windy day without the water dummies. Brother of a friend was the guy who sent it out.

My understanding is that there's a wheel that rolls along as the train is pulled up the lift hill which generates the upward force to keep the dogs off the teeth. Thus, I've heard that if it's raining, the wheel doesn't have enough friction, the dogs drop and make a terrible racket.
