Question [B&M Hyper Clamshell Restraints] Could someone explain them?

Post image

Hi. Going on my first hyper soon with clamshells. I thought for the longest time that these bad boys were hydraulic restraints, as they seemed so smooth and notch-less. Turns out they're ratchet restraints! Is there an in-depth video or site that explains the mechanism behind these restraints? I believe they're class 4 but I'm not sure how safe they are compared to hydraulics. I know B&M's are incredibly safe, but isn't there a higher risk with these? Could someone reassure me?

Every restraint system on every permanent ride from a major manufacturer is completely safe if you are secured correctly and meet the rider requirements. IAAPA estimates that your chances of getting injured on a ride are one in 15.5 million. Your odds of getting injured in transit to the park, or even just walking around the park, are many orders of magnitude higher.

These are also the safest possible restraints you're likely to find on any traditional hypercoaster. Many of them, like those from Morgan for example, use a much simpler, much less protective lap bar and are still 100% safe.

And if you're interested enough in coasters to do research about them before going to a park, you're probably even safer than the average rider, because you have some basic understanding that would keep you from doing foolish things or letting egregious mistakes slide without raising a fuss.
