Rotating ski slope with Stöber and Torriani

An inclined, rotating disc with a diameter of 12 m on which 3 people ski at a peripheral speed of 30 km/h. The system is powered by Stöber drives where the rotating movement is realized with a Torriani slewing ring bearing and the inclined movement with NEFF lifting spindles. The complete drive and control system was developed and commissioned by ATB Automation.
