Silver Bullet's brakes

Wednesday, July 14, 2004 5:27 PM
I was looking at photos on RCDB, and I came across this.

What is that? I can see the brakes in the back... Is B&M using hybrid magnet / friction brakes?

That's what its looks like, but we would need to look at Nitro and Silver Star, who both use magnetic braking on their final brakes to see if it is similar to that.

Its true, B&M has gone Magnetic. Finally, No more Friction brakes. Even though B&M has used those for so long, I think this is a good step forward. Going in the direction Intamin is, Without the snapping cables ofcourse. Static magnetic brakes should be very safe and less power consuming.

BTW, Is this a cross breed between a B&M and an Intamin. Why does that piece of track remind me of somthing.

Magnetic brakes are also quieter than friction, and Knott's has sensitive noise issues to deal with. That's why the lift will have magnetic anti-rollbacks, too.

B&M uses a combination of magnetic and friction brakes. The magnetic brakes slows the train down just a tad, enough to reduce wear and tear on the friction brakes.

Woa....magnetic rollbacks? Have those been used before? (Is that why Millenium Force is so quiet?)

Talon has them, IIRC. So does Millie, Stealth/BorgASM, and others I'm sure.

Looks like it has the regular Anti Rollback Teeth. Only the brake sections look like they have full magnetic and some friction.

Of course it has regular teeth...it's the chain dog that will be magnetic. It will only contact the teeth if the train rolls backwards, otherwise the lift should be silent.

I can't picture that Mamoosh. Can you explain sil vous plait?

Remember that magnetic brakes can never stop a train. A train in magnetic brakes is free to roll, even if it can only roll slowly. Intamin gets around this by using kicker wheels to stop a train entirely. I applaud B&M for taking the hybrid approach. Very wise!

I believe Premier Rides also do this hybrid braking on both of the Mummy coasters. Works very good IMO.

I'd guess that the "Intamin track" in that pic is just a temporary support for the track...

That "Intamin track" is supports for the magnetic brakeing: http://rcdb.com/installationgallery2536.htm?Picture=7

Well, if you know about it, share it.

'Tuan, what moosh is saying is when a train goes up a hill with a chain dog, it clicks going up(locking it "in place" from going back). On Silver Bullet the lift will not make that noise due to the magnets. In effect, it won't be hitting the Chain Dog unless it rolls back, in which case the Magnetic Chain Dog will catch it. Am I right? Rideman? Moosh?:)

Still don't get it!..Oy!! So you are saying that the magnets repel the chain dog unless there is a power failure? I guess I have to see it in action.
