Nice pics
Wonder why they made those breakover sheaves so big

[KZ]

I dunno but they sure look neat. They must weight a lot because the look pretty solid.

Hole N Wall has counterweight across the street. I suspect counterweight ropes could take a while to inspect.
Wall lift top terminal is on edge of cliff. No room for extra tower. Larger sheaves have bigger bearings and axel for added weight. Notice Riblet style swing gaurds. Picture taken shows rock band with 50' of snow below!
YAN was a major owner of this area.
The Reut (root) lift was named for Dick Reuter a retired Mt. Manager of Kirkwoood. Dick worked also at Squaw Valley during the 60s.

I think its kinda funny that the Reut (the run) is located off of chair 6, not 11 (the reut). Ryan, when did LE let go of the area?

Now these are for sure the largest sheave wheels ever. Compare the wheel size to the tower.

We have the same sheaves on our lifts, we call them Gondola sheaves... I don't really know why :) You're right they are quite big. Great pics, again!!

[floridaskier]

Do they make it any smoother, or require less maintainance, or is it one of Yan's different ideas that didn't make it on too many lifts?

[Kelly]

Strength issue only. Used on many lifts since early 70s. Just more apparent in posted pictures. Yan pulled out of Kirkwood in 93-94.
Riblet also used larger sheaves (complete line) on some of its bigger lifts. Most went to beer fund from the scrap yard. Um I mean went to buy NDT kits.

So do we- it must be a Yan term. Supposedly they made one or two gondolas, but I couldn't tell you where they were or of they still exist.

You never rode a Hall!

[KZ]

No, they are bigger. Anyways, one gondola was at squaw

[liftmech]

Yan's 'Gondola' sheaves are bigger than Hall's standard line sheaves. I believe Hall built theirs to 16" in diameter, the same as many others. Their depression sheaves were only 12", though, so they make the regular sheaves seem larger. The 'Gondola' sheaves on Yan lifts are 20".

[edmontonguy]

To gain some perspective regular hall sheaves would be like the rims off an old Honda Civic whereas the Yan Gondola sheaves would look more at home on an Escalade

[KZ]

well some upgraded rims on an escalade. The standard rims are probably 16 or 18, so some "dubs"

In this picture you can see the size difference between the two size YAN sheaves.

I'm sure not. I compared the support sheaves of the Belle-Neige quad (Dopp) with the double (Hall), and they are really bigger.

[KZ]

Allan, are those the gondola sheaves? If they are, the ones at kirkwood were almost twice that size.

[skier2]

At Keystone hall built a gondola where the river run dopp/ vonroll gondola is now...
as usual with yan's detachable lifts, it had problems and was removed.

[skier2]

sorry, i meant at keystone, yan built a gondola... it was removed

Those are the Gondola sheaves... Those are the 20 inchers, I didn't think they got much bigger than that... I'll get a picture of one in my arms, then we'll see ;)
