For some reason I remember those type of turns being called a Bachmann angle station... maybe I imagined it or maybe I'm just wrong. If I'm right it works like this picture. The rope is supported on a series of (white in this pic) pins on the bullwheel. When a grip comes in the pins get pushed up out of the way.

BACO was the original manufacturer of those bullwheels as I recall. Now "part" of POMA.

As Allan said, the chair has a special ramp on the grip to push the pins up as it enters the bullwheel. There is a ramp above the bullwheel that pushes them back down. There was a deropement on one when the upper ramp was not replaced after maintenance.

BACO (Bachmann & Co.) was a swiss enterprise. Today, BACO is the agency of POMA in Switzerland: www.baco-ag.ch

I'm pretty sure it was Doppelmayr to Poma. The old Peak chair was a Doppelmayr bottom drive. Poma made that terminal a top drive, which looks really weird with the tri leg design. Then they added new towerheads, a new Poma return and chairs.

The original lift was a 2nd hand Poma and was moved by Doppelmayr when they insatalled the new Peak chair.

The downhill side of that lift is very similar to the POMA setup on Breckenridge's Snowflake chairlift.

[skierdude9450]

That system was used on t-bars and platters long before Snowflake was even thought of.

After looking at this design for awhile--I think I've got it figured out--the returning line wraps around that outer bullwheel before coming back down the mountain. Why would they choose this design over a simpler design, say, the BACO model, with only two bullwheels?

No special bullwheels or canted assemblies, all the deflections are normal bullwheels, dead simple.

I want to know how many people wipe out on these corners in surface lifts!

You would know how many peoples fall out of the lift in cause of the turnings? That aren't so much! In Europe, particularly Switzerland there are much more surface lifts than chairlifts/gondolas/etc. Only the beginners have some problems to ski around the corner.

I am aware. I was simply pointing it out.

Actually, not many. With a T-bar, you don't really have to do anything special. It will slowly pull you until you're straight.

I find lifts that turn on the course of the line are quite interesting. I know of a few, but my true question is : How do you get that back to the same terminal?
All of the lifts i've seen that have turns do not turn where there are chairs running the down line.

(Here are some photos of lifts with turns:)

(Above: South Ridge Triple at Killington, VT)

(Above : Snowflake Double at Breckenridge, CO. To my knowledge, this lift actually makes multiple turns.)

So how exactly do these (mainly fixed grips) meet up at a common load/unload terminal?
I would imagine it's easier to have the turn on a Highspeed Lift. Here is the Riva Bahn at Vail, CO.

The cadence systems in the terminal turn the chair, not a bullwheel.

So, what exactly is the deal here?
(Sorry if this is slightly unclear)

On Snowflake, the portions of lift line above and below the turn are pretty much level since the bottom load and unload stations are a considerable distance away from the turn.

While you question isn't totally clear, I'll try to explain.
The Cadence system does turn the chairs through the terminal (they arrive, detach, convey through the angle, then re attach and exit).
BUT the cable is either "turned" by horizontal sheave assemblies OR bullwheels inside the terminal depending on the degree of the angle.
Hope this helps.

The Sunshine Village gondola (Banff) has two midstations but I think only one cable. I think the first turn (70 deg ??) is done with bull wheels but there is no loading or unloading. Cabins come off the line though. The second may not even turn at all but is for loading and unloading.

I am always amazed that bottom and top stations do not get pulled out of the ground. How much force is there on turn stations? Logic says less than a top or bottom station with 180 degree turning, but still does anyone know how much?

Village Express - Snowmass, CO
West Buttermilk - Buttermilk Mnt, Aspen

[Kicking Horse]

I can tell you for a fact that the Village Express does not turn. Along with the West Buttermilk Express.

The Elk Camp Gondi does make a turn at Snowmass....
