  2. Roller coaster wheel assembly - Wikipedia

    en.wikipedia.org/wiki/Roller_coaster_wheel_assembly

    Some older wooden roller coasters utilize steel wheels throughout the assembly. The benefits of the polyurethane or nylon/polyurethane blend are low rolling resistance, high load endurance, smooth ride, and high durability. [2] Some manufacturers' coasters have a larger gap between the up-stop and/or side friction wheels and the track.

  3. Underfriction - Wikipedia

    en.wikipedia.org/wiki/Underfriction

    A roller coaster wheel assembly. The underfriction wheels are on the bottom. The three sets of wheels clamp onto the track. On a roller coaster train, the underfriction, up-lift, or up-stop wheels are a device to keep the train from jumping off the track under intense movement. [1] The design was patented in 1919 by John A. Miller. [2][3]

  6. Roller coaster train - Wikipedia

    en.wikipedia.org/wiki/Roller_coaster_train

    Roller coaster wheels. Roller coaster trains have wheels that run on the sides (side friction or guide wheels) and underneath the track (upstop, underfriction, or underlocking wheels) as well as on top of it (road or running wheels); these lock the train to the tracks and prevent it from jumping the track. The side wheels can be mounted on the ...

    A brake run on a roller coaster is any section of track that utilizes some form of brakes to slow or stop a roller coaster train.The most common type is the friction brake, often called a fin brake, which involves a series of hydraulic-powered clamps that close and squeeze metal fins that are attached to the underside of a coaster train.

  8. Side friction roller coaster - Wikipedia

    en.wikipedia.org/wiki/Side_friction_roller_coaster

    A side friction roller coaster is an early roller coaster design invented by Edward Joy Morris. The design introduced side-friction wheels to help prevent trains from derailing during curved portions of the track. In addition to weight-bearing wheels traditionally located on the underside of each train car, friction wheels were added to both ...

    en.wikipedia.org/wiki/Lift_hill

    Lift hill. A lift hill, or chain hill, is an upward-sloping section of track on a roller coaster on which the roller coaster train is mechanically lifted to an elevated point or peak in the track. Upon reaching the peak, the train is then propelled from the peak by gravity and is usually allowed to coast throughout the rest of the roller ...
