two rollbacks today!!!

Tuesday, April 5, 2005 11:47 PM
On greased lightning at SFKK. They were having problems with the launching mechanism, the SFKK mechanics were all scratching their heads. I noticed on the control panel that it still says viper on it. I never did get to ride it, it would had been my first shwarztskoff.

For future reference, that would be spelled Schwarzkopf (good guess though).

Also Beast Tamer, in it's former life at SFOG, it was called "Viper" hence why it still has that name on the control panel.

I wouldn't exactly call that a rollback. If they don't have to get out the crane.....

This is an older model counterweight shuttle. I don't understand how it could not completely launch unless somehow the train was prematurely disengaged from the pusher bob and that seems very unlikely. Once the counterweight starts to drop it has to drop all the way--right?

I could see this happening on a flywheel model where the clutches could slip. But with this model, even if the cables and pulleys were all rusted, I would think all that weight dropping should still be enough to propel an empty train through the loop.

I think the last time I was there they were having problems with trim/brake adjustments. If they are not set right it will launch too slow or too fast and either way that can spell possible problems with operation of the coaster.

On these coasters, a speed measurment is taken at launch.

If incorrect speed is measured, the controller will adjust the launch trims to keep the train from going through the loop and successully launching.

This could be Pusher issues, break issues, or computer/speed measurement errors.

In any case no big deal to work with.

This is a 1976 counterweight model, are you sure there are computer speed measurements and adjustments? If so this must be a recent modification, I sincerely doubt they were built that way.

Jeff, I too doubt the computer speed measurements but I know what I saw couple years ago when I went right before Stark Raven Mad. They definitely were adjusting the trims to make the ride run better. *** Edited 4/7/2005 11:31:39 AM UTC by beast7369***

You are correct, my experience is with the flywheel model.

I really do not know about the weighted model for sure. I just assumed it had the same safety checks.

Maybe not!

Greezed lightnin (AW) is date 1978 and does this, or so I have been told.

Mods or original.... I do not know.
