Here are some more pics of the old yan hsq parts in the sun valley boneyard. They have the 7 Yan motor rooms lined up. Each motor room has all the original equipment inside, plus shelves full of extra parts.

WOW!!!
Its a virtual YAN museum!!!
Whats most interesting to me is, with all of YAN's innovative genius, he overlooked such simple things that meant so much. Example, you would think that any jar head would know that rubber springs are not a good thing to keep your chair attached to the cable. Your car tires freeze, right? Next is the maintenance side of things in the terminal. Sounds like YAN never even took maintenance into consideration. Kind of like having to take out a motor mount to change a fan belt in a car.

Wow, it appears that Sun Valley purchased all new Yan carriers for its HSQs just because they replaced the lifts. That's probably why Christmas (didn't have them in 88 when the lift was installed) and Frenchman's have them. I would think some of the other resorts like Pico, Mt. Snow and K-Mart, Sunday River would like to purchase some and put them on their Yan HSQs. These carriers are really nice and comfy.

So, Quicksilver went to Sun Valley? LOL. I thought they'd destroy every part of that!

As far as i understand we had the bubble chair to "test" it out to see if we wanted to buy some for our then yan hsqs. Well then things went sour on yan that year and we decided not too. I think we ended up donating the chair to our ski museum in ketchum, but dont take my word for it.
As for the extra carriers they are not quicksilver they are from our hsqs. we originally wanted to sell all of our parts after the 96 retrofit. unfortunatly everyone retrofitted too so nobody bought them. now we keep those chairs for no reason other than extra parts for christmas and frenchmans.
As for the motor rooms they make great sheds. Anything else around the boneyard thats for the yan hsqs is used as extra parts for the current yandopp lifts. even the gearboxes!!! which are still used except for lift 5 and 10

don't be too hard on yanick regarding his use of rubber marshmellow springs to provide constant force at various temperatures. he may not have realized at first that there is a lag time when the compressing force on these springs is released, when cold, which is why his redesign of the Y7 grip included coil springs.

next time you're on any poma, ctec or doppel HSQ, take a look at the springs in use on their support/commpression assemblies.

So why did Christmas and Frenchman's keep the Yan style chairs, but the other retrofitted HSQ didn't?

Doppelmayr uses coil springs, at least on the supers we've got. I've not been around CTECs that much- do they use rubber or coils?

[shoemanII]

have seen rubber springs on dopp/ctec and poma hsq support/compression assemblies. seems to depend on the year of manuf. poma has used coils and belleville washers on their fixed grips while yan used coils, leaf springs, air bags and rubber too!

i feel the designer is faced with hard choices when selecting a spring that should: provide the required and consistant forces over the deflections of the assembly, be suitable for -40 to +100 temps, be resistant to corrosion/cracking, be resistant to taking a "set", be capable of multiple cycles over many years.

Well new chairs are obviously expensive and considering the fact we retro'ed all seven lifts, we decided to go reuse some yan chairs. I think after the retrofit only a few chairs had doppelmayr chairs and they have slowly been switched over to doppelmayr chairs. Well I think we finally got to lift 3 and 8 and decided they are just fine and we have plenty of replacement parts so why spend oodles of money on new chairs we dont need. Plus rumor has it Earl Holding likes the teardrop look. (that might be the reason we bought those damn things to begin with, lol)

[CH3skier]

Thanks for answer. I was thinking cost as well. Hadn't skied there for a few years until this year and had noticed the old style chairs.

[SkiBachelor]

Well, the carriers that are currently on the Christmas Express were not the ones that the lift originally came with, rather the newer YAN HSQ carrier that came out in 1992. So I'm guessing that Sun Valley probably got the 1992 YAN HSQ carriers for free after LE shut down and installed them on Christmas and Frenchman's.

I think they were cannibalized from lift 5 (for christmas lift 3) and 8 (frenchmans) already had them (8 was built in 95 if i remember right). All i know for sure is the ones in the boneyard are the old ones from our lifts (they are the newer models post 92).

Yeah, I forgot about the bellville washers; we've got three towers with them ('81 and '85 vintage lifts). We also have several of the leaf-spring Yan assemblies still floating around.

10-4 on the hard choices. Seems to be as many kinds of compression assemblies out there as there are lift manufacturers.

[Allan]

Our YAN 4 over 4 assemblies (the ones with the looooong arms with a two-er on each end) have leaf springs and bellville washers. You have to watch the 3/4 inch bolt that goes through the arm and provides tension... they like to fail, dumping the washers, nut and bolt combination down onto skiiers at a high rate of speed.

Any new photos of the boneyard? I'm gonna go there ASAP :).

[Peter]

As of August 2007, it looked the same. Is there anything you would like pics of?

[Superchairliftfan]

Maybe pictures of the controls and more pics of the Whistler chairs.

We actually re-organized the place a fair bit in a the spring - also added all the old chairs from 1/4 and Dollar lifts.

Expect to snowshoe in, it doesn't get plowed much.

Any chance you could get one of the chairs from Whistler (lol, grip included) to B.C. (in Canada) by courier???

[Peter]

There is only one Whistler chair there.
