suspended coasters with ostrs?

Why dont they just put in lap bars, it would make it so much more fun! I mean theres no loop, and it would be safe

Oh so true, but even if there were loops there is no need for OSTR's. Even though out of the 3 suspended coasters I've ridden, I've had little to no headbanging. However headbanging or not, lap bars always give a much more open feel.

There is something they call 80°-90° banking on Arrow suspended coasters. Without OTSR restraint system, your entire upper torso would be yanked out and hanging off the side wall of the car. Either that or you sprain your neck. So there IS a reason why they're built into the design. Don't get so ignorant people...

Use a lap bar like on B&M speedcoasters. And lots of coasters with more than 90 banking have Lap Bars. Of course, there you arent swinging.

That's the problem. The swinging chasis is constantly transitioning from left to right and those motions are in addition to the track banking.

Yes I am seeing your point. Unlike other coasters, suspendeds swing from side to side quickly what I'm guessing would give you whiplash when you only have a lapbar. Thanks for pointing that out to me.

I know that coming off that second turn on Top Gun at PKI you get over 90 degrees. Great feeling

Why do B&M dive machines have OTSR's? They never go upside down. It doesn't really make sense to me.

Now I am guessing that since it is a vertical drop that your upper body would hang and be uncomfortable. The OSTR's are there to hold your upper body up for less back strain. This is especially needed if there is a holding brake for the drop, like in RCT but I'm not sure if it has one.

THe only reason Arrow Suspended coasters have OTSR is because the tub was made from the Arrow Looping coasters. So instead of spending extra money redesigning it, they just put the OTSR on.

The swinging of the car on suspendeds could be just as well handled with a contour seat as with OTSRs. The loads aren't the heavy, and if the OTSRs were really supporting your head, then your head would be hitting them. If the OTSRs aren't touching your head then they aren't transfering any forces to your head. The angle of the banking doesn't result in any lateral forces since the car is aligning itself with the force vector when it swings. Only the shock absorbers that prevent excess swinging result in any lateral forces and these are quite minimal.

Certainly, the lateral forces are much lower than you normally experience on many woodies. Ride Twister at Knobels some time if you want to try some lateral forces several times as great as anything on a suspended with not OTSRs, Jephry may well be correct that the OTSRs are left overs, or it may just be that they are there to keep nervous parks and insurance companies happy.

On the topic of Suspended Coasters... I find them very fun rides, I wish Arrow still made them. A hyper-suspended would be awesome! I wish I could have ridden Top Gun at PKI, but when I was there, they were doing maintinence.

I think Suspended Andrew said even if there were loops there is still no need for otsrs. Yes there is. I went on Batman the ride in the front seat. on the first drop I was completely on the restraint because there was not enough speed yet for me to be in my seat. Same with the loops. So there is a rwason for otsrs.

Here is a topic I started at Guide to the Point a long time ago asking the same question. Thats where my answer came from

First of all Batman is not a suspended coaster, it is an inverted coaster. Big difference. And although I believe that inverted coasters should always have OTSR, if you had a lap bar on a looping coaster (of which there are many around the world) the lap bar keeps you in your seat. You said that you came out of your seat and were completely being supported by the OTSR, you don't think that an elaborate (FoF) or tight locking (shuttles) lap bar system would have held you down? In my opinion only inverts and stand ups NEED OTSR.

As far as the topic goes, I don't think that suspendeds need OTSR. I never hold onto anything while riding them and I never hit my head. That leads me to believe that they are not required, especially since the only part of my body that touches the OTSR is my gut/pelvis which is exactly the same place that would be in contact with a standard lap bar.

Jephry is correct about using the same basic tub design as their loopers. Also because Arrow originally planned on including inversions on the suspended design. It quickly became apparent that the swinging combined with inversions would be too great of a strain on the trains and/or riders, so the inversion idea was scrapped. Arrow did build a working scale model of a looping (corkscrew actually) suspended coaster. I saw that video on a website, but alas, I cannot remember the link.

"X" marks the spot in 2001!

Alpenflung was the only Suspended with lap-bars, built by Swarzkopf it only ran for 7 days.

Big Bad Wolf was originally supposed to have lap-bars, but Swarzkopf went bankrupt and Arrow had to finish it, that is why BBW is the most intense suspended.

Even with inversions, there would be no real need for lap bars on a suspended coaster. By there basic design, suspended coasters must never go to any real negative G's or they would tear themselves apart. The car would go to one side or the other to the limit of its movement them hit the stop hard. This would be no fun for the riders and would result in serious damage to the car and track.
