[3] By 1977, Thiokol had decided to stop producing ski lifts and sold their designs to two employees, Jan Leonard and Mark Ballantyne.
[5] Leonard oversaw engineering at the company's Salt Lake City facility while manufacturing was performed in Sacramento, California, where Ballantyne worked.
Prior to the merger, Garaventa had built only a few lifts in North America, including Aerial Trams at Snowbird, Utah, and Palisades Tahoe, California.
The company built the world's first detachable high speed quad chairlift in 1981 at Breckenridge Ski Resort in Colorado.
[9] In 1996, Doppelmayr's European holding company purchased the ropeway department of Von Roll, a Swiss manufacturer which had been making lifts in North America since the mid-1980s.
[11] In 2003, the company installed its first UNI-GS detachable chairlift, the Panorama Quad, at Gunstock Mountain Resort in Gilford, New Hampshire.
[15] In 2007 and 2008, Doppelmayr CTEC constructed two notable lifts at Jackson Hole, Wyoming, and Whistler Blackcomb, British Columbia.
[17] In February 2021, the new Pucci chairlift which went into service in 2020/2021 season at the Timberline Lodge ski area in Mount Hood, Oregon furnished by Doppelmayr USA[18][19] broke down due to an electronic failure[20] causing 42 people to become stranded.
