    The location of the counterweight on this lift is crazy. Another example of this is Argentine in keystone.

      Yan was pretty innovative in the mid 70’s with counterweight locations. There was no place to hang a big concrete rock behind the lift so he found a “remote” location. Alpine was pretty straight forward with a deflection sheave arrangement on the rear mast. Old “Hotel” lift at Union Creek had a unique setup where the counterweight cables deflected 180 degrees off the rear mast, ran inside the main horizontal beam and the deflected out the uphill side to the remote location!😜

    Copper has proposed in their Master Plan replacing Alpine with a high speed quad that would start at the same location as the current lift, but would be extended uphill to the top of Copperopolis.

      When do they plan to have it installed?

        Not any time soon. Just because it’s in the plan does not mean it will happen at all, in fact. The current plan is to maintain it as it is, with the exception of a drive and control upgrade (happening now) and moving the bottom terminal uphill to make way for a development (happening next summer).

          Keeping the counterweight setup in the relocation converting to hydraulic? We gave High Point the hydraulic conversion when it came up north to us.

          This sounds like “Skytrac or Doppelmayr completely replaces the loading area”, which is what they did with Blackjack to make room for Three Bears.

          Donald, we may just keep the current terminal and convert it to hydraulic with Blackjack’s old stuff. Wouldn’t be difficult, and it would be cheaper for sure. As I said, that’s next year and there are too many things happening now for us to worry about that.

    does it cause extra strain on the towers to have the counterweight so off center like that? seems like especially with such a long lift the lateral forces on that bottom terminal would be pretty high.

      No. The counterweight on any lift is isolated from the towers. Also, there is simple geometry at work here- when you’re working with a steep lift gravity is your friend, in that the tension force required for traction on the drive bullwheel is aided by the sheer weight of the installation. In this case we’re talking 12,000′ of haul rope at roughly 4 pounds per foot, plus 205 chairs at 88 pounds apiece, multiplied by 1726 vertical feet. That’s not the full formula but you get the idea. The counterweight comes in at 27,000 pounds, lighter than many smaller lifts.
