Modern theme park, fairground, and amusement park rides are heavily dependent on hydraulics. Without hydraulics, some of the most popular rides around the globe would be unable to operate. These hydraulic systems' commencements result from large tanks filling with compressed nitrogen gas along with hydraulic fluid. The tanks pressurize the nitrogen gas to 290 bar, or 29 MP. The devices beneath the tanks open a number of valves once the nitrogen gases reach the desired pressure. The fluid is then propelled to the motors which power large drums and winches that are located underneath the roller coasters' tracks. These winches then pull on the catch cars by steel cables and the trains shoot across the tracks at astonishing speeds.
KingdaKa, at Six Flags Great Adventure (in Jackson, NJ, United States) uses a hydraulic launch with seven pumps, four tanks/accumulators, and 32 motors. Launch types that may be used on other rides instead of the hydraulic include pneumatic, linear induction magnet, and catapult. The linear induction magnet launch (LIM) is used on the roller coaster Batman and Robin at Six Flags Great Adventure as well as the Tomorrowland Transit Authority at Walt Disney World (in Orlando, Florida, United States.) These systems use electromagnets along the launch to propel the trains forward without using catch cars. LIM launches are not very popular among fast roller coasters since they can never possibly attain accelerations as high as hydraulic launches.

LIM launches are not very popular among fast roller coasters since they can never possibly attain accelerations as high as hydraulic launches.
Catapult launches, commonly powered by diesel engines or large counterweights that are dropped to propel the roller coasters, are very similar to LIM launches. Like the LIM launches, these are incapable of attaining hydraulic launch speeds. The Rockin' Roller Coaster at Hollywood Studios in Disney World uses this type of catapult launch.
Presently the highest competitor to the hydraulic launch systems, the pneumatic launches are able to produce acceleration just as fast as hydraulic launches while reaching great maximum velocities. However, many roller coaster designers prefer hydraulic launches due to the loud volume of pneumatic launches. Dodonpa (located at Fuji-Q Highland Amusement Park in Fujiyoshida, Yamanashi, Japan) is one of the fastest pneumatic launches in the world. It’s launch accelerates riders from 0 to 107mph in 1.8 seconds; an acceleration of 2.7 G's. Hypersonic XLC in King's Dominion (in Doswell, Virginia, United States) used a pneumatic launch which accelerated riders from 0 to 80mph in 1.8 seconds but closed 2007.
Within every one of these thrill rides’ systems are hydraulic motors. Within these motors, there are seals to keep them functioning properly. High quality seals from Colonial Seal have been proven to improve reliability of roller coaster motors and reduce downtime across amusement parks worldwide.
