    is it just me or does the line guage on Yan high speed lifts seem smaller than leitner-poma and doppelmayr?


    • Donald Reif August 11, 2019 / 7:35 pm

      I don’t see any of that on Carpenter at Deer Valley (which was converted from a Yan, though unlike most of the Doppelmayr and Poma conversions, Garaventa CTEC completely replaced the terminals on Carpenter to do the conversion).

    Why is the line speed on this lift 900 while the other converted Yan is 1000?


    • Thomas Jett November 11, 2019 / 1:18 pm

      That may be a mistake on Peter’s part. In my experience, 1 also has has a reduced line speed.


      • Peter Landsman November 11, 2019 / 7:12 pm

        So I looked at the Yan records and 1 can actually only go 850 while 16 is 900. They were built different years.


        • Kirk November 11, 2019 / 7:46 pm

          900 fpm because, the spacing is at 90′ with 6 a second interval.


        • randomguyu March 12, 2021 / 11:20 am

          where did you get the records?

    This lift has the worst looking terminals; worse than standard CTEC hit speed chairs


    • Donald Reif January 27, 2020 / 10:17 pm

      These were refitted Yan terminals, mind you. Of course, what sets these and June’s DoppelmaYans apart from most DoppelmaYans is that on the other DoppelmaYans, the terminals were essentially modified to take on the appearance of Spacejets with no underskin (like Sun Valley and Schweitzer), or outright replaced with new Spacejet terminals (Whistler).

      As a mechanic I think they look great- lots of room inside instead of some cramped enclosure with no headroom.


      • Raj Thorp February 15, 2020 / 3:34 pm

        Mainly what I meant was the terminal skin and paint at the top


  4. Kirk March 12, 2021 / 11:53 am

    Mammoth 16, 900 fpm, 90′ spacing @ 6.0 sec interval. Mammoth 1, 850 fpm, 85′ spacing @ 6.0 sec. Both 2400 pph. This data is from the 1996 Doppelmayr conversion.

    Has Alterra said anything about this chair’s now-twice-delayed replacement?


    • skitheeast June 24, 2021 / 9:51 am

      Nothing has been said publicly.

      My two cents is that it would be nice of them to upgrade to an eight-pack instead to show that the extra delay resulted in a better lift.


      • Marcus June 24, 2021 / 11:29 am

        An 8 would be nice, but at this point it needs _something_. Of course, my preference would be to turn the existing top terminal into a midstation and continue to the top of 5, or better yet, the top of Dave’s, but yeah yeah I know.


  6. ski man October 18, 2021 / 6:00 pm

    at the top terminal you can still see the pancake terminal witch is the greenline part of it


      • pbropetech October 19, 2021 / 8:12 am

        It did. Originally, Yan’s detach terminals were basically tunnels over the conveyor equipment with a fixed-grip motor room housing the drive equipment. The returns were even more low-profile with only weather coverings on the tire banks.


        • Donald Reif October 19, 2021 / 9:39 am

          They weren’t all that different from the first generation of Doppelmayr’s UNI terminals (the ones seen on Keystone’s Outback Express, Ramcharger 4 prior to its reinstallation as Shedhorn 4, Skyliner at Mt. Bachelor, and so on).


    • Marcus October 19, 2021 / 3:11 pm

      Are you saying the top terminal is from Greenline at Whistler, or am I misinterpreting?


      • pbropetech October 19, 2021 / 4:16 pm

        Misinterpreting. He’s referring to the green-painted part of the terminal, which might be the only part of the original terminal skin left.


        • Marcus October 19, 2021 / 4:22 pm

          Ah yeah, that makes sense, thanks. I had never seen the Yan detachable terminals before..those were cool-looking lifts.


  7. skilifts4876 October 21, 2021 / 7:30 pm

    when were the safety bars added to the Yan high speed quads


  8. ski man November 19, 2021 / 6:22 pm

    here are some pictures

    I like those old colors of the terminals

    This must’ve been one of Yan’s last lifts.


  11. Marcus October 9, 2022 / 11:52 pm

    Did anyone see even one piece of evidence that any preparatory work was done this season to prepare for this lift’s wholesale replacement next year? I was expecting to see new tower footings or, like, a tree or two cut down.


    • Kirk October 11, 2022 / 7:48 am

      If it happens ?? All the work could be easily done in one summer.


    • Wes January 16, 2023 / 7:23 pm

      Yes, there is evidence of preparatory work done last summer for the new 16. The new top station will be closer to the top of 4 and thus they did a bit of work to get ready. Encore has been widened, and looks to be the new lift line. A number of trees were removed at the top of The Acts, opening the entrance up considerably. Before we got the 20 feet of snow in the last few weeks you could see a wooden stake at the top of The Acts that marked where a new tower is going in. That spot is pretty much where you used to enter the run on the left to avoid a wind stripped area. This is may not be an issue anymore as the removal of a small group of trees seemed to change the wind loading in the area.


      • Marcus February 6, 2023 / 5:30 pm

        Interesting! Does this mean they’re likely to get the chair out of the avy chutes completely? Looked like they have some clearance challenges over there with the heavy snow load this season.

    Whenever I see a picture of an unmodified Yan Hsq I have to remind myself that they are actually old and from the 1980’s. Compared to what others were offering at the time, it is very easy to see why they were so popular. You could probably fit 2.5 Yan Hsq terminals into a single CLD-260, and poma was still using poma alpha terminals as main drives in the mid 80’s. Even later in the early 90’s, Doppelmayr’s early UNI-G was bigger (and in my opinion not as good looking) as the Yan Hsq terminal. Poma did not really have a uniform terminal in the early 1990’s as they were experimenting with the challenger terminal.
