A hydraulic launch is a type of launch that propels trains to high speeds. It consists of several hydraulic fluid chambers, compartments separated by a piston and several launch cables attached to an engine. The engine is a large wheel that pulls the launch cable.
History[edit | edit source]
The first installation with a hydraulic launch was Xcelerator at Knott's Berry Farm, built by Intamin. Subsequently, Vekoma introduced their motorbike roller coaster, which was powered by a hydraulic pump.
Hydraulically launched roller coasters have suffered from extended downtime due to maintenance issues with the launch system. As a result, the technology has fallen out of fashion, with Intamin favoring LSM powered roller coasters instead.
