@ liftmech; what is the issue with the rubber mounted assemblies... I have seen them , but never had to service them.

They have to be replaced every so many years or if you have all original like my area did from 95 they wear out then you have sloppy rockers. Seem like they were starting to wear then by mid winter we had to change out several that really got sloppy on our compression towers if it starts leaning you will get tower faults from the cps. All the compression towers will have new rubber bonded bushings this year. And will be getting support towers on a schedule so we don't have this happen again. There is some benefits of these no grease in the towers and less chance falling on people, more line dampening, when changing sheave the rockers don't flop around. I guess you win some you lose some. I will post pics of some worn ones almost 20 years old don't know how they lasted so long but way worn some fell out without having to press them they got so bad. Like not having to grease that lift but when these things start to go they go.

We had them at Tamarack when I worked there . the heavily loaded break over assemblies drooped and had to be plumbed up after 2 years of operation . I also recall that the lead in sheave frame had a traditional glacier bushing and shaft (greased) to allow for proper brittle bar actuation.

Nate pretty much covered it but on my end I just don't like how fast they wear out. I have a 28-year-old detach quad with glacier-bushed line assemblies, but tower 1 was replaced with a rubber-bushed set when the bottom terminal was relocated in '99. Since then I've rebuilt both sides twice and it looks like next season will be the third time. The bushings just don't hold up (or hold alignment). Meanwhile, on the rest of the line I've only rebuilt 5 of 68 assemblies.

Back on topic, I suppose

Yeah, I've seen the tower 1 sheaves on American Flyer in the video I made of it.

I guess the resort is the party to make the call about whether or not lift towers get catwalks.
