Yea probably. I will post some pictures of links and belmont tommaorw. You can tell these yan lifts are slightly different then the others. Pretty cool knowing ive ridden their first lifts :)

Do they (Belmont and Links) have the angular carriers built from 1" square tube? Those are the earliest Yan carriers I've seen in Colorado, on lifts built before 1979.
L/E also supplied the towers and return terminal, as well as the profile, for Blackjack in 1996. For some reason we put a Doppelmayr hydraulic tension unit on the return that same year, and not a Yan product. So Blackjack, while not being a completely new Yan lift, still has relatively new Yan parts.

Yep 1"
Tops have been changed to a "3" tower design.
Some older assemblies still still have POMA sheaves (metric).
Baileys Beach was a double.
Hanson gearbox
Riblet service brake
YAN e-brake
YAN dog brake

As to smooth the Yans aren't bumpy chair lifts at all a great ride.
I talked to a couple lift mechs at Alta and they couldn't be more positive on the Yans they simply love them.

What exactly is in those Yan Operator boxes? I tried to look in the one at blackcomb, but I could only see a phone and paddles, Also, the old base 10 controls were in the yanbox right, not the operator box? Does anyone have any pics of the Base 10? Thanks

Ryan, did those lifts have e-brakes when they first opened? Squaw had a problem with Exhibition (rollback) and a few people go hurt.
The history of problems
that plague Squaw Valley
Squaw Valley and its aristocratic Boston-born owner Alex Cushing have been plagued by safety problems for more than a decade.
Depite the ski resort’s prestige as the largest Tahoe ski area and the site of the 1960 Winter Olympics, a state industrial safety board in 1974 ordered fines of $6,700 for safety violations.
Most of the fines were for failing to have operative emergency brakes on the ski lifts.
The resort has had at least seven serious chair lift accidents since the 1960 Olympics, resulting in scores of injuries.
In 1965 Cushing was charged by the state with not complying with safety regulations after a life gave way and several skiers were injured when the chairs began to run backward.
In 1971 a state safety inspector shut down the Gold Coast Chair Lift when he found it was operating without a bull wheel brake. Cushing paid a small fine on that.
And in 1973 an accident on the Exhibition Chair Lift resulted in misdemeanor charges against Squaw Valley.
The biggest fuss over Squaw Valley safety, however, occurred after a 1974 accident on the Exhibition lift in which seven skiers were injured.
The bull wheel emergency brake was found by state inspectors to be badly worn and oil soaked.
Safety violations were also alleged on the KT 22 Gold Coast and Emigrant lifts.

It sounds like Squaw's fines and accidents were completely maintenance-related. Oil-soaked e-brake pads? Come on! Someone didn't clean up their mess or fix their leak. And I wonder if the lift without an e-brake (1971) had a problem with that brake, and Cushing told the maintenance crew to run without it...
Our Yans run smothly as well. We keep tweaking them to fix some of the inherent Yan issues, but in general, they're great lifts. As Ryan B has mentioned in earlier posts, many of Yan's problems have been blown out of proportion due to the simple fact that bad news spreads five times faster than good. If a lift runs smoothly for its entire lifespan, it doesn't make headlines.
We have four lifts with the Base 10 low-voltage controls; I will try to get some pictures of them. In general, the drive and the low-voltage cabinets are in the motor room regardless of manufacturer. You can put them in the shack, but then you have to build a bigger shack.
