If that were the case, Yan probably also supplied the hydraulic tensioning. The chairs and “Y” lifting frames are defintely not of the same vintage, so they were probably added by Yan during the relocation. All the Yan lifts that I have ever seen with this style of chair don’t have any lifting frames.
Yan did not supply the tension- it was purchased new from Doppelmayr and installed as part of the lift’s relocation from old I-lift. The same happened at Mountain Chief the previous year and Sierra the following.
Blackjack was built using parts left over from old “I Lift” (Motor Room and machinery, sheave assemblies, tower tubes, grips and chairs, return carriage, etc) and new parts (Y cross arms, tension system, new bull wheels, etc) purchased from Lift Engineering. It was installed by Copper’s in-house Installation Team. The lift was designed to be converted to a triple if needed.
Are they redoing the bottom terminal of this lift? If you watch the video on Twitter that Copper Mountain posted of the Three Bears Chair, you can see a newer looking terminal next to the new Three Bears one.
They replaced the bottom terminal of Blackjack this summer to make room for the Tucker Mountain Lift. I believe it is similar to the A51 Lift’s bottom terminal at Keystone.
It is indeed getting a Skytrac tension return though slightly refined from A51 as it has more walkways and handrails. I completed concrete for the return, the lift shack and tower 2 in September. I also helped to shorten the existing tower 3 to adjust the profile so as not to overload the assemblies. Tim and Alan set steel in October, so short of some handrails that got misallocated but should arrive soon to the terminal is done and the lift should be load testing the mods soon.
Why is the Tucker bottom terminal concrete projection so tall? I don’t remember making that compensation when we installed original Blackjack bottom terminal.
The location of the new Tucker lift is southeast of the old 4 foundation so to reach the ground the foundations got tall; a tremendous amount of fill was taken from autobahn trailand around the new 4 bottom to get the grade under the tucker terminal.
Due to the Y-Crossarms, I believe that Yan helped with the relocation of this lift in 1995. It must have been one of their last relocation projects.

What are cross arms actually used for?

If you’re talking about the Y part, that’s a lifting gantry for changing sheaves or removing and installing sheave assemblies.

Lifting frames are used to jack up the cable using a winch to lubercate the sheaves. Older lifts dont have them and the towers get real loud.

That’s not why they get loud. We still lube everything on towers without lifting gantries, it’s just more of a pain.

Looks like it was supplied by Skytrac. https://twitter.com/CopperMtn/status/1184870806830096384

Like all the other lifts in the Copper Bowl, Blackjack has a capacity of 1200. It also has a length of about ~2260 ft.
