Kanonen ("The Cannon") thrills its customers with its extreme acceleration, reaching a speed of 75 km/h in less than three seconds with the help of 20,000 horsepower. When the Liseberg Amusement Park in Gothenburg ordered the new attraction, it turned to ÅF-Kontroll for quality assurance.

 

ÅF-Kontroll visited the manufacturer together with the client's representatives to scrutinise the production documentation that detailed the technical specifications for welding, testing and coatings. After installation ÅF-Kontroll carried out non-destructive tests using X-rays and ultrasound, and reviewed the acceptance tests with staff. This was ÅF-Kontroll's first assignment for Liseberg, but it had already inspected rides at Gröna Lund Amusement Park in Stockholm.
