Editing Yan Lift (section)

===Whistler, British Columbia, accident (1995)===
Yan detachable lifts were subject to a series of accidents, most notably the Quicksilver lift at [[Whistler Blackcomb|Whistler Mountain]] in British Columbia, Canada. The Quicksilver accident killed two and injured eight on December 23, 1995.<ref>{{cite web |url=http://www.geog.uvic.ca/dept2/undergrad/honours/nixon_e.PDF |title=Disaster and Emergency Management: The Quicksilver Chairlift Incident |last=Nixon |first=Emily |publisher=[[University of Victoria]], Geography Department |date=April 2004 |url-status=dead |archive-url=https://web.archive.org/web/20080408210447/http://www.geog.uvic.ca/dept2/undergrad/honours/nixon_e.PDF |archive-date=April 8, 2008 |access-date=March 17, 2015 }}</ref>  The accident occurred when the emergency stop was used repeatedly.  A chair started sliding downhill and struck the next chair which got stuck on a tower. This continued several times before a total of four chairs fell.<ref>{{cite news | first=Larry | last=Pyn | title=Minimizing the risks on B.C.'s ski lifts | date=February 9, 2008 | publisher=[[CanWest Global Communications|Canwest Interactive]] | url=http://www.canada.com/vancouversun/news/story.html?id=60e7f2b3-fad4-4b5e-ab6d-85b4248c69f6&k=68164&p=2 | work =[[The Vancouver Sun]] | access-date = February 29, 2008 }}</ref> The main problems with the Yan high-speed lifts were the chair grips.{{citation needed|date=June 2016}} These were designed so that in order to stay connected to the cable, the chair had to be subject to gravity. The Yan grips, unlike most operating today, did not have high-tension coil springs, but rather rubber "marshmallow" springs that exerted much less force on the cable. The repeated emergency brake application was enough to shake the chairs free of the cable. The majority of government safety inspectors failed to detect these problems.{{citation needed|date=June 2016}}

The Quicksilver chairlift, which served the Whistler Creekside base area, was replaced by the Creekside Gondola in 1997, built by [[Poma]].{{citation needed|date=June 2016}}
