I just went to Breck on Saturday and my friend brought up the possibility that there might be two different haul ropes, with two large bullwheels in the midstation. But the drive is clearly on the top station (hence the stack) and I don't think that such a small engine could power the other haul rope (assuming there is one). Anyone know anything about that or anything else I might want to know?

No, there's only one haul rope used on the entire length of the lift. The bullwheels that are used in the mid station are used to redirect the direction of the rope. In many old lifts, it's common to have two seperate haul ropes, but as technology advances, there's no need to have this type of setup.

Well, I'm that friend and I am very curious to see how the Peak 8 super connect works. Do you think that you could tell me how everything works on that lift? Thanks!

Welcome to the forum Boeinglover.
To help you better understand what I'm talking about, here is a picture of a Garaventa high-speed quad with a mid-station similar to the Peak 8 SupperConnect at Breck. As you can see, the two bullwheels located in this mid station direct the haul rope to a different direction. I hope that clears stuff up.
Sorry about the file size of the picture, it's a big one.

Well, that's interesting. I didn't think that they could fit two bull wheels in the midstation. it really doesn't look like the Poma has the bulge like the Garaventa has, maybe there are just a bunch of sheaves on the dowside. That's what I think.

The Breck lift does infact have a sort of bulge though i am uncertain if it has 2 bullwheels. In a midstation where loading is done such as on the Peak 8 the carriers travel outwards at a 45 degree angle then turn 90 degrees as they enter the loading area. This avoids the need for skiier to make turns while attempting to load the lift and allows a more conventional loading profile. Bullwheels for turning are typicaly more effective on sharper turns. As sheaves do not have the ability to effectively turn the line within the same radius as a bullwheel, once the sheave assembly exceeds that radius it is easier to design the terminal with bullwheels.

Perhaps the bullwheels are in front of each other, instead of side by side, like in the Garaventa. I should ask for a tour.

The line turn on peak 8 is pretty small and i doubt would need the like of bullwheels. Also to facilitate a bullwheel to turn the downloading side it would have to have it's hub well outside the terminal housing. This is absent on the terminal and unless there is a complicated set of sheaves within the terminal driving the line inwards towards the loaded side, in order to travel around a bullwheel completely enclosed in the terminal, the chances are the line is turned by a set of sheaves.

No, there are no bullwheels in 4-chair's midtation. Poma uses 550mm deflection sheaves in all their terminals, and this one is no different. Here is a rough schema of the midstation: red is the haul rope, blue are the horizontal deflection sheaves, green is the path the uphil carriers take (hence the bulge on that side). The rope is also deflected downward to bring it away from the grips, but I have omitted that part for clarity.

Wow, be sure to get some great pics. I want to look at them. I think that we'll be able to see exactly how the midstation works.

It uses deflection sheaves just like liftmech stated...There are no bullwheels at the mid. The inside of the midstation is actually very empty. Just has a bunch of tires and belts and a few sheaves. Everything is PTO driven off the haul rope with belts. There are four PTO "systems"...One at each corner of the terminal.
The "bump" edmontonguy talks about is just for loading purposes.
