These lifts can also accelerate incredibly fast with a super high top-speed. Way faster than the humans riding it would be able to handle. The main part of this system is actually developed by ProDrive, Eindhoven. I had a tour there, they have a really interesting factory. Super small, yet super efficient, automated and suitable for many many different products. Doesn't look like a factory at all, they even have research in the same building as it. I'd imagine they'd be more than happy to give you a tour and show you the way main part is built and developed (spoiler, it's very interesting).,(reply>), Square Play'n d,(reply>), I'd say it's an eddy current break (Wirbelstrombremse) as used in Free fall towers,(reply>), I do not. ProDrive, which is where I got a tour, was given the assignment to make the lift move up and down, simply said. They were told they would not have to look into a separate safety system for the case of failure, the company that gave ProDrive the assignment said they'd either invent such system themselves or get another company to do it, so ProDrive didn't know anything (or at least couldn't say anything) about the safety system for the case of power failure.,(reply>), Square Play'n Do you happen to know what makes the lifts not fall down in case of a power failure?,(reply>), I don't think acceleration would be much of a problem look at the tower of terror rides in the various Disney parks those elevators get up to 40 mph in 2 seconds and then pull back down faster than the speed of gravity which gives the riders excessive amounts of airtime (Negative G forces) So the acceleration and speeds are definitely possible and able to be handled by humans... Also the elevator moves horizontal in the Florida version of the ride
