The LE (Lift Engineering or Yan) Type 7 was the type of high speed quad that had the problems. It was the flat design on the Yan section above

[SkiBachelor]

It looks like the Friendly Giant at Lake Louise.

I had more pictures of this lift, but I can't find them. DANG

They got very creative. I like it, personally, it looks nice. If they made one Keystone would have bought it, if anyone. To have both terminals like that they would need a vault drive.

Keystone needs too much uphill capacity to cater to the numbers that ski there. Although it would be nice if they had put in a couple of HSDs to limit the number of skiers on the mountain.

OK, thanks for the explanation.

I think yan had a few other models of hs lifts but the type 7 was most common. The J6 drive seemed to be unique taking on the very familiar boxy look.

[highspeedquad]

I personally don't like the look of any Yan HSQ. I don't like them in general.

The type 7 was the most common Yan detachable grip, but it was the type 11 that failed catastrophically at Whistler.

I have only seen two HSD like that, and I think they would be a pain in the ass to work on. I mean everything is exposed and if there was freezing rain or a heavy snow storm, it would take some time to get that lift operational again. It kind of reminds me of the LE Type 7.

I long time ago, TR (Formerliftforman) mentioned that the lift mechanics would have to get out brooms and start brushing and banging at stuff to get the lift moving again because everything was frozen solid. Not fun stuff.

No matter how tight your terminal is, there will be times when everything freezes solid. In December (I think) we shut down the entire mountain save the Eagle due to wind. The next day we showed up an hour early to begin cleaning snow and ice out of the Bee, Exceleator, and the Flyer. Timberline sits in a more protected location, but since we couldn't run the Flyer we couldn't get anyone to it.

This isn't the best pic of snow inside the terminal, but it's all I've got right now.

Do the snow brushes like the ones on timberline helpp keep keep snow and ice outof the terminal?

Does anyone have any photos of what the Yan grips looked like, that failed?

I don't know anything about them realy, other than I've read from some other posts that they relied on gravity or the load on the chair?

(I'm even a little surprised companies like Doppelmayr have adopted a bistable mechanism for their grips, because it leaves the possibility for the grip to have an open resting state, vs. the Poma grips which always reset-closed...)

Well there was only one Type 11 built and I doubt anyone has any pictures of the grip other than what I have posted in the past of the Yan Bubbles. That was the lift that failed so you might be able to see the grip in those pictures. But they look pretty much like the Type 7. There is also a site that shows some close up pictures of the grip too.

[Duck]

I'm more curious about how they mechanically differ from what's out there now by other manufacturers. The "Type 7" or whatever numbers don't really mean a whole lot to me...

I presume you already know how most detachable grips work and how they rely on an object to open and close the mobile jaw to detach and attach to the haul rope successfully. Yan's grips worked on this same principle, but instead of having an object that pushes something down to open up the mobile jaw, it relied on a mechisim that would push the two side arms inward. However, Yan's grips relied a lot on gravity to keep grip force. I have no clue on how gravity grips work and they are also band in most countries now. :o

So that must be why they have the terminal brushes. Is there a larger problem with the Flyer about snow because some parts of the terminal are very much exposed compared with newer lifts?

florida..if im not mistaken..what you called the omega station was wrong..the latest is the satilite series..

[SkiBachelor]

Actually, the Satellite series is not the latest L-P terminal, it's actually this kind:

These pictures came from a member of the alpin-forum.com site. Sorry, I don't remember who took them though.

[edmontonguy]

Those are definately NOT poma but infact the newest version of the Leitner terminals. They seemed to have dropped the lietnercake when this terminal was adopted. it is the successor to the one we're used to seeing in north america but has yet to be built in NA.

[SkiBachelor]

I know those arn't POMA, but I was just refering to Mike's post about how the Satellite terminal is not the newest L-P terminal design. I believe the terminal design in the pictures I posted above came out the year Leitner bought POMA or the year after. However, that terminal design is the newest L-P terminal design, even if you don't consider Leitner of Europe to be L-P like it is in North America. I'm sure you could order this terminal if you wanted from L-P of America.

I hope that clears stuff up.

[Zage]

The Satellite terminals are used on Poma lifts in Europe.
