2nd generation freefall

Monday, March 18, 2002 11:18 AM
How does the freefall(ex.My.Hydes Nasty Fall @SFWoA, Demon Drop @ CP) transport ridersforward? Also how does it hold riders and drop them? And how does it transport riders down to the station?

Thanks too anyone who can answer these questions.

Im building one of these outta K'Nex so i need to know how it works.

At least I dont call a vertical loop a "loopdie-loop"!

My take on these...hopefully someone smarter will come along soon - shouldn't be hard, LOL. The Intamin first-gen rides are the ones like Demon Drop where the "car" drops, then tilts so feet face forward, and they come to a stop along the track. Then the car moves backward until it hits a "catch mechanism" where the bottom is lowered back to the normal, upright position. It then rolls back toward the station for unloading/reloading.

The second-gen rides are like the Pitt-Fall, or the SFKK ride (Hellevator) where the seats are in rows along the outside of the tower. I could be wrong, but I'm pretty sure that's the difference as Intamin's technology advanced...

Edit: how could I forget the name hellevator....that's my generic name for all drop-rides....D'OH!

You go backwards up an elevator lift then once to the top you roll forward to right above the track then you drop roll on to your back until the brakes stop you. Then a wheel moves you backwards and you get flipped almost upside down as you are being brought back down into the station. Understand? Its really hard to explain.

None of those helped guys. Sorry, but I need to know how the "mechanisms" work. See.

Like how does the car roll backwards towards the station? I know it has that little wavey thing where the wheel of the car hits it but how does the wheel ride from the regular track to that part without getting in the way?

At least I dont call a vertical loop a "loopdie-loop"!

I think what you mean is a 1st Generation Freefall.

The car moves backward to the rear of the tower (from the station) and engages a vertical chain lift. Upon reaching the top of the tower, the car moves forward to the freefall position. Once it reaches the freefall position, the ride computer double check the blocks to make sure there are no other cars in the way before the car at the top is let go. At this point, the car is still upright and is rolling on wheels on the bottom of the car.

Once the unit is dropped, the track flattens out. At the bottom of the track, the car is laying on its back. Obviously, it will need an extra set of wheels to support it in this position. Those wheels are located on the upper rear of each car, there are two of them. They only actually function when the car isn't completetly upright, and during the freefall portion of the ride to make sure the unit stays stable. If you look in the station, these wheels are plainly visible on the cars.

If all goes well, the computer had each car come to a stop just past the "reversing drive." The reversing drive is what actually takes each unit and moves it from the brake section of the track, turns it upright again, and transfers it to the lower station track, which is also called the "slope." Feedmotors (tired attached to drive motors) push the unit backwards, but the upper riding wheels mentioned above do not go backwards, but rather down and through a kinked track, while the "bottom" of the car is lowered by a chain mechanism. The motion created os a swoop, much like a door on a hinge.

The top wheels disengage the uprighting track totally at the point. The car drifts backwards, down the slope, its speed regulated by more feedmotors, until it reaches the station, where it completes this cycle.
