Editing Yan Lift (section)

===1985–95===
Lift Engineering entered a new market of [[Detachable chairlift|high-speed detachable chairlifts]] in the 1980s. Whereas other ski lift firms spent as much as four years developing these lifts, Yan installed its first after only one year of research and development, at [[June Mountain ski area|June Mountain]] in California.<ref>{{cite web  |title=Yan High Speed Quad Retrofits 20 Years Later |date=March 15, 2016 |url=https://liftblog.com/2016/03/15/yan-high-speed-quads-20-years-later |access-date=April 5, 2022 }}</ref>

By the late 1980s, Lift Engineering was one of the largest suppliers of ski lifts based in North America.

Lift Engineering also was an important player in the [[funitel]] market in the late 1980s.  The quad mono cable, or QMC, was invented by Kunczynski (US Patent 4,848,241). The lift consisted of four separate loops of cable, strung between the upper and lower stations. Two cables were run in the uphill direction, and two were run in the downhill direction. The cabins would be mounted between the cables. But, because the cables were looped, once the cabins reached the upper station, the cables would loop back downhill not carrying a load. Only one of these lifts was ever built, and first opened to the public in 1988 at [[June Mountain]].<ref>{{cite web |title=QMC Debuts at June Mountain |url=https://www.seilbahnen.org/de/index.php?section=downloads&cmd=266&download=12217 |access-date=April 5, 2022 }}</ref> The owners allegedly had difficulty getting the cables to run in synchronicity. The lift also developed the same grip problems that occurred on the Yan high-speed quads, and ceased operation in 1996.
