hydraulic vs LIM

Did You Know? In the midst of designing the original Schwarzkopf shuttle loop coasters, Schwarzkopf and Stengel toyed with the idea of using LIM technology for the launch? Yes! They knew LIMs way back then, but the reason cited why they re-designed for another method was that LIMs in the 70s was simply not a cost-effective solution to deliver their product to market. Just an interesting tidbit I thought I'd share...

I know that their is a small chance but what if there was a launch on both side of the track, then the ride would operate like wicked twister. I think that I am having trouble excepting that fact that I will be waiting in line for 3 hours to ride a 10 second ride.

Uh, no.

The other major thing is that hydrolic/air presure luanches go MUCH faster at a faster time. You get SHOVED into your seat for 4 seconds of time. It's MUCH more intense than LIM or LSM. That feeling you feel once they kick on is what you feel the whole launch on a hydrolic/air pressure launch.

Back to the Schwartzkopf shuttle loops, about a third of the shuttle loops that RCDB has listed in their Schwartzkpof Shuttle Loop database ( here ) are listed as weight drop. So, Jeff, we're both right and wrong. :)

Wrong. Stick to DDR. ;)

The Schwarzkopf shuttle loopers used a flywheel system. Basically, get a really heavy wheel turning really fast, then engage it to a pulley to snatch the train. It's kind of like putting the wheels of a car on jacks, getting the wheels spinning really fast, then kicking it off the jacks.

Acutally, he wasn't wrong :oP

There are some Schwarzkopf shuttles that use the flywheel system and some which use the weight-drop system:

Yeah, if you would've read the rest of the thread, you'd see that was mentioned, numb nuts. ;)

DELETED!

An interesting fact(note numbers are not exact) Each launch on WT could power 400 homes for an hour.

Ha ha, and only missed it by a post too!

The reason I was so quick to say that Schwartzkopf shuttles are weight drop is because I've only been on one of them: Greezed Viper Wave, which is indeed a weight drop model.

Thanks for the explanation of the launch system Montu. It leads me to believe this operates more like an air launch. It's compressed nitrogen that powers the ride after all. The hydraulic fluid is used to transfer the energy to the the turbine which transfers the energy to the wheel with the cable wrapped around it and the cable transfers the energy to the pulling carriage. The hydraulic pump does however charge the system. Sounds like a nice system. Hydraulic lines have been known to rupture but that could easily be prevented by replacing the lines from time to time. If they did rupture and the train didn't quite make it over the top that would be an exciting ride. lol Riders would be safe, but some wouldn't know that.

A ruptured line would make a big mess.

It depends on what line ruptures, If the pressure line went the train won't make it. But in the unlikely case of the return line giving out, it would probably increace the performance.
