What roles do hydraulic fluids play in roller coasters?

Best Answers

Coasters use hydraulics in a variety of ways. Perhaps the most common is in restraint locking systems. Because fluids are non-compressible, mechanical or electrical valves can be used to control fluid flow in locking cylinders. When fluid can flow, the piston can move; when the valve closes, the piston is locked in place. read more

The one place where hydraulics are generally NOT used on roller coasters is in the braking systems. That may seem odd, considering that most automobiles have hydraulic brakes. But there is good reason. Coaster brakes usually involve a braking surface crashing violently into a fixed brake unit, generally a metal fin entering a closed caliper. read more

Hydraulic fluid is forced into cylinders using massive pressure. When this pressure is released, the fluid spins a cable drum which is attached to a catch car, which pushes the train forward. This system provides an extremely fast and intense launch. read more

Go to roller coasters and they still use low tech pneumatic or hydraulic brakes to grip and slow or lock the car. Sarum Hydraulics is good on manual over ride pumps for braking systems but roller coasters are not something that we have ever designed for. read more

Some roller coasters use hydraulics as a launching mechanism. For example, two of the fastest coasters in the world, Top Thrill Dragster (Cedar Point) and Kingda Ka (Six Flags Great Adventure) use a hydraulic launching mechanism. Essentially, hydraulic fluid is pumped into a piston that compresses a chamber of nitrogen. read more

Most roller coasters rely on fear-inducing heights and speed from gravity to excite riders. Top Thrill Dragster, at Cedar Point, Sandusky, Ohio, is no exception. However, instead of relying on a chain or cable to laboriously pull the coaster up its first hill -— in this case, a 420-ft hill — Top Thrill Dragster relies on kinetic energy to propel coasters up its hill in mere seconds. read more
