    As of April 16th’s Alpine Update, Tim Pfister is scheduled to return in early May with the new assemblies. The old ones clearly did not work out for whatever reason, hence why the haul rope is derailed from two towers as shown. If/when this lift is completed for 21-22, it will be a massive lifesaver on peak weekends, tripling capacity from just Red running to the summit.

      It looked to me like only two more combo assemblies are needed. The lift already has a bunch of them and there probably weren’t enough from the old Snow Bowl lift alone. Whatever chairs had gotten stacked up previously have been removed/re-hung. Lift ahould be good to go for next season.

        Shouldn’t the initial engineering have told them it wouldn’t work? How are number of sheaves and type of assemblies determined?

          I’m not totally familiar with the process, but there are a number of formulas and calculations that are run to determine line load at any given point along the line. As we learned from out experience on the Flyer, those calculations aren’t always correct in the real world. I can see from the photos that the two deroped towers have a combo assembly on the heavy side but a two-rocker support on the light. Knowing the lift is a bottom drive, that means that the light side will be pulled tight every time the lift starts; given that the heavy side is essentially neutral (otherwise they wouldn’t have put combos there) they should have picked up that the rope would float off the assemblies on the light side. $0.02

          Pbropetech has interesting points. With the light side being the pull side, where the heavy side has a depression or combination assembly, the light side needs the same. Otherwise, the haul rope would float above the assembly, at least at each start up.

          The towers that are derailed were actually configured as hold downs. I hiked up last October to look at the lift, and they had the haulrope up but not the chairs. When the chairs were put on, the weight was too much and the haulrope hung below the sheaves. I would guess that if the lift is running, the light side is pulled up to the sheaves, but those two towers need to be combos.

          Collin- In the photos it appears the upper tower IS a combination assembly while the lower is a 2 sheave. Not debating what you saw, but in my 40+ years of installing and maintaining ski lifts I can’t remember the last time I saw a 2 sheave hold down assembly.

    Was the basic problem more terrain changes in the Black Line than the Snow Bowl? This requires more depression or combination assemblies than existed on the original. This was discovered after the lift was erected. Finding replacements was not in time to get it running for this season.

      I’m not sure exactly, but the line here is definitely different. Snow Bowl’s liftline was mellower and was pretty consistent if I remember correctly. This lift starts with a runout on Hocus Pocus, gets progressively steeper along Black Line, gets much steeper than it had gotten at Stratton on Pitch Black and then mellows out to near-flat at the top. They wanted to iron out electrical issues, construct the top ramp and add safety bars in December and January for a mid-season opening (Whether or not this was possible in the first place is up for debate), but they discovered these issues around President’s Weekend and delayed the opening to next season.

    Does this have an entirely new haul rope or did they splice in a new section? This lift is longer than it was as Snowbowl at Stratton.

    I love the 16 sheave assembly at the bottom.

      I’ve seen lifts where the heavy side was a combo and the light side was a depress. That’s the way the derailed towers on this lift were designed. The problem is the light side needed to be combos as well, since when the lift isn’t moving, the haulrope sags too much.
