CCI Fast Stops on Brakes

Saturday, March 30, 2002 7:43 AM

I have been wanting to ask this. How come on some or if not most of CCI coasters have sudden or fast stops on the brake systems before coming into the station? One example would be Shivering Timbers at Michigans Adventure I also think The Boss has the samething at Six Flags St. Louis. Does anyone kind of understand what I'm asking?

it has been my experience that all woodies do that. I don't know why, though, but its not just woodies either. Shockwave and Demon at SFGA (Arrow loopers) do that.

I would just assume it's coincidental considering CCI doesn't program the braking sequence, and the people who do, custom create the sequence for each individual coaster based on the different profile and entrance into the station from the last brake run.

BTW, Howdy, It's Jes, and I'll get around to answering your last e-mail later today!

Nope, coasters with the ever classic skid brakes gently come to a stop. Gotta love those skid brakes!! :)

At least partially it's because that's the simplest way to do it: When the train reaches the brakes, start a timer. The train slides into the closed brake; the timer counts more than long enough for the train to stop, then the brakes open and the train proceeds. If the ride doesn't have a PLC on it (Raven, for instance) then the brake just stays closed until the operator pushes the button to open it.

Also, the brake exerts a constant braking force, and for those of us who are more accustomed to the variable braking force found on Arrow coasters, that's just a little unusual. That's because Arrow's brakes are air-applied, and since air is compressible, the braking force is reduced a little as the fin pushes through the caliper.

I would think it depends on how the person who programs the ride sets it up.

When the Hoosier Hurricane 1st opened, it had 1 trim,3 stop brakes on the run. The train came to such a screeching halt that CCI added an extra trim, therefore, there are 5 brakes to stop the train. Maintenance can adjust the air pressure to lighten up the brakes if needed.

The CornBall's system seems more advanced and better. If the train is full, the brakes go into a "trim mode" and slow the train to a nice speed towards the station. Ironically, if the train only has a few riders the train comes to a halt then it's released to enter the station. (Why it does this I do not know.)

It probably comes to a complete stop when nearly empty because there is less weight to stop. Just as the heavier something is, its gonna take longer to stop (like the braking distance of a small Saturn compared to a big rig.)

I dont think it has anything to do with a change in pressure.
