A video of the ride.
Kanonen ("the cannon") was a steel roller coaster located at Liseberg amusement park in Sweden. Built by Intamin, the ride featured a hydraulic launch and opened in 2005. The tightly packed layout is the result of a limited area to house the ride. On December 30, 2016, Kanoen closed permanently and will be replaced by a Bolliger & Mabillard dive coaster called Valkyria.
In 2002, Liseberg's only looping roller coaster HangOver, a Vekoma Invertigo model, was removed. The park contacted several roller coaster manufacturers with the aim of introducing a new looping ride, with the winning bid coming from Swiss company Intamin. Lars-Erik Hedin, technical director of Liseberg said "Due to the good experiences with Balder and the impressive catapult launch we decided to mandate Intamin again with the project".
After departing the station, Kanonen's 16-person trains are accelerated to 72 km/h straight into a 24 metres (78.7 ft) high top hat element. This is immediately followed by an air time hill and a 20 metres (65.6 ft) high vertical loop, the first inversion of the ride. After a highly banked turnaround, the trains pass through a heartline roll before entering the brake run, bringing the ride to an end.
As with many launched roller coasters, Kanonen was susceptible to rollbacks when the train does not gain enough momentum on the launch track in order to make it over the top-hat and rolls down backwards. Kanonen has magnetic brakes along the launch track in order to slow the train down if this happens. Rollbacks usually only happen if it is windy or the track is wet, but other factors can affect the launching system.
On June 8, 2009, the right conditions meant that a train got balanced at the top of the top-hat with 14 passengers on board.
