Diagram comparing a standard lift hill and the B&M pre-drop lift hill. Early Bolliger & Mabillard coasters feature an element known as a "pre-drop", a short drop after the top of the lift hill and before the start of the first drop, designed to reduce stress on the lift chain.
A lift hill gives the train potential energy by raising it to the highest point in the track (and not significantly accelerating it). A launch track gives the train kinetic energy by accelerating it to the maximum designed speed (while not significantly raising it). A launch track normally includes some form of brakes.
The launched roller coaster is a type of roller coaster that initiates a ride with high amounts of acceleration via one or a series of linear induction motors (LIM), linear synchronous motors (LSM), catapults, tires, chains, or other mechanisms employing hydraulic or pneumatic power, along a launch track.
A slipway, also known as boat ramp or launch or boat deployer, is a ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on trailers towed by automobiles and flying boats on their undercarriage .
Large (high amplitude) half-pipes make possible many of the aerial tricks in BMX, skating and skateboarding. For winter sports such as freestyle skiing and snowboarding, a half-pipe can be dug out of the ground or snow perhaps combined with snow buildup. The plane of the transition is oriented downhill at a slight grade to allow riders to use ...
Launcher/Kicker – A curved bank a rider uses to launch into the air. Roll-in – A long sloping ramp used to gain speed. Step-up/Eurobox – A funbox type ramp consisting of a bank with a flat at the top and a second, higher flat after it; in other words a bank-to-flat setup with a section removed from the bank part.
A mega ramp, or megaramp, is a large vert ramp structure, often used in skateboarding and freestyle BMX. First built in the 1990s and 2000s, megaramps are twice or more the size of earlier vert ramps. MegaRamp (styled with title caps and without a space) is the name of a mega ramp event organization and promotion company.
The typical height of a vert ramp is 11 ft (3.4 m) to 14 ft (4.3 m) with anywhere from 6 in (150 mm) to 2 ft (0.61 m) of vertical on top. Vert skating ramps can be made with 6 in (150 mm) to 1 ft (0.30 m) of vertical while vert skateboarding ramps are typically made with 1ft to 2 ft (0.61 m) of vertical in order for the skateboard to launch ...
