I have found a YAN lift which appears to have the original faulty grips

I met the administrator of remontees-mecaniques a couple weeks ago and asked him specifically about that lift, he said the it had been replaced with a higher capacity lift.

Can't imagine there's many (if any at all) un-modded Yan detachables around anywhere. Those grips not only have proven safety defects but they also lack any manufacturer support in this day and age.

:shifty: I was skeptical about that old YAN express lift still being there after the grip problems. But other country's with less strict safety laws may.

From what I understand Yan grips had 2 major issues:

1. the spring mechanisms were sensitive to sudden changes in temperature, especially freeze-thaw cycles.
2. they relied partly on the force of gravity to apply pressure meaning that in the event of a sudden stop on a long, steep span grip force could be reduced.

The lift in Iran appears to not be very steep and operates in a warmer climate, It should be able to operate for years to come without issue as long as parts are available.

People often blow the Yan grip issues out of proportion due to the incident in Whistler in the 90's, people often forget that this incident was the result of a rare worst case scenario: 100% downhill load on a very steep lift that crossed the freezing level on the day, the grip slip happened after several e-stops in rapid succession.

Can someone tell me what happened to the Grand Summit Express at Mount Snow. There are 6 Yan HSQ's in the east. The Grand Summit Express at Mount Snow, Barker Mountain Express at Sunday River, Superstar and Snowshed Express at Killington, and the Golden and Summit Express at Pico.

All except Grand Summit Express were modified the same exact way. They had the grips, sheaves, and other line gear replaced. They also had a Poma Challenger glass top added to both terminals. Superstar and Barker got new Poma Omega chairs in 2004. The rest kept the Yan chairs.

Grand Summit Express was modified differently. It got new grips, sheaves, and line gear, and a glass top at the summit, but the base terminal didn't get the glass top. In 2011, the Yan chairs were replaced with Poma Omega chairs with footrests and a glass top added at the bottom.

I also heard rumors that Grand Summit Express was modified earlier than the others which was actually before the Quicksilver accident. Is that the reason for the base terminal not getting the glass top or is it something else. I will note that Grand Summit Express is the only Yan HSQ in the east that is top drive. Maybe they didn't think they needed the glass top at the return, but the other bottom drive lifts got it because the return would be exposed to more harsh weather conditions, but they wanted all the drive terminals to be covered.

You cant blame them they made the lifts cheaper

But since this one is on barely an incline it makes since it would be safer

Yeah it does. I also noticed that is has similar colors to Ski Bromonts lifts.

I really want to ride an unmodified Yan detachable so I can say I survived it.

I believe this instagram account shows the same lift, many interesting photos.

Apparently, it may have come from Silver Star ....

Even one of the Yan detachable quads from Silver Star lives on; you can ride it at Nazhvan Park in Iran where faulty grips may be the least of your worries.

Nope. Still there.

The person who said that lift was taken out might be referring to Friendly Giant at Lake Louise. It got the new Pol-X-West grips that worked in the same terminals, so it still had all the Yan line gear and chairs. It was taken out after a newer Leitner HSQ made it redundant and unnecessary.

Interesting, we got in to talking about Yan lifts, he found them quite interesting since they're not common in Europe and mentioned that an unmodded Yan detachable quad had been removed and replaced with a 6 pack, can't imagine there's too many Yan detachables in Europe...

Never quite understood that, basically there were 2 lifts, the Friendly Giant and the Glacier running side by side, the Friendly Giant basically made Glacier redundant until Glacier was replaced with a Leitner detachable which then in turn rendered the Friendly Giant redundant. Why install a second similar lift to replace a a fully functional one? are Yan parts really so hard to come by that it's justified? Even with Yan being long gone I wouldn't have thought the cost of maintaining a Yan lift would be that expensive compared to buying a new lift.

With Lake Louise it may have something to do with park permits and having a lift in place to negotiate removal of for something else. I think this is why they still have the two old double chairs in place at Louise but not functioning.

Generally regulations regarding the operation of heavy equipment such as cranes and excavators in national parks are quite strict which explains why many of Lake Louise's now derelict lifts remain standing, there are 3 that I know of Eagle has several towers and the drive terminal, Olympic pretty much looks like it could still run other than the top controls having been vandalized and an incredibly rusty haul rope and the old Von Roll gondola still has a few towers standing.

I suspect something a little more complicated with Friendly Giant, Lake Louise seems to be pushing to remove all of their Yan lifts for whatever reason, Ptarmigan, which was a Yan fixed grip quad was replaced with a Poma fixed grip quad a few years ago and I believe I read somewhere that Paradise was either replaced or modified for this year, haven't been to Louise this season yet so I can't confirm this.
