I think everyone used chains before they found a reliable way to get the tyres to take the carrier around the contour

yep

Is that at Brek ?

[SkiBachelor]

I don't know.

Looks alright, good for its age

[Eric]

That doesn't look like the first HSQ found in the world

[SkiBachelor]

I wasn't sure, but it does look old.

That pic is not from Breck. I'm 100% sure that is not breck.

Not the same grips, not the same towers, not the same chairs, it's not this lift.

Conveyor chains were the first method of moving chairs around the contour, as Cameron noted. I don't know how maintenance-intensive Doppelmayr's are, but Poma's take a week per terminal to work on in the summer. Then there's the small problem of the cadencing system being a 'passive' system, instead of the more modern 'active' tyre banks. A passive system means that the chair comes into the terminal and either is caught by the chain or not. An active system, on the other hand, constantly fine-tunes the spacing of the carriers as they come through, eliminating (or almost) chair collisions.

Does the Orange (formerly Quicksilver) chairlift have gravity grips????

[floridaskier]

I dont think so. I think it had the box-style grip in use until about '94 (?).
(no actual info on this, don't hold me to it)

[Dr Frankenstein]

It's not DS grips.

[liftmech]

The former Quicksilver doesn't have DS grips? It must have been retrofitted, then, because the DS grip was the first detachable grip and it was on the Quicksilver when it was at Breckenridge,

[floridaskier]

The chain spacing system on the older Doppelmayrs like at Vail looks pretty simple. The chair is caught by two sort of hook things that are spaced out as far as the distance between the chairs should be. The chains catch the chair. But what would happen if one of them missed the chain hooks and the next one crashed into it?

We discussed this a while back with the POMA Angel terminals. If the lift operator was able to see that the chair missed and stopped the lift in time, he would be able to put it on the rail, but if he missed , well there would be a problem. Doppelmayr's seem not to have this problem from what I have seen.

The operator at St-Sauveur was going crazy because he didn't wanted to stop the lift! He was running in all the ways!

Do you mean he would put it on the maintainance rail and put it back next time the spot came around, or push it back into the chains that it missed?
