Its the last tower on Lift #7 Grewhawk (sun valley). Ever since i have worked there i have always wondered who made that tower (the one on the right side). I was thinking it might have been a YAN or Doppelmayr prototype that never made production.

The first photo is from lift 10 (tower on the right) and the second is a back side of it from lift 10.

I think there is a similar tower on Yan's first HSQ at June Mt.

Mount Snow’s Grand Summit Express built in 87 has 3 of those, the banana rotates on the round cross arm, See the pictures of the top two in the lift section.

Were those lifting frames used for special sections of the lifts?

I think that type of cross arm was used because the tower loading needed an 8 sheave and the Yan S-4 came in 2, 3 and 4 sheave assemblies, so to get a 6 or 8 he used a banana (it’s what he called it) with 2 - 3’s or 4’s, this type of banana moves so the sheave loading stays equal. The lifting frames on those seem much stronger than the other ones he used, likely for the heavier loads.

Some closer ups.

We still have several of those made by Lift Engineering. They are called a "rocking banana" The plateform rotates and the sheave frames rotate to evenly distrubute the load to all sheaves. We haven't had any problens with them and not a bad design IMHP.

We also have some on an '82 fixed triple, so does Loveland on their #2 ('85? triple).

Liftmech- Yours have the box tube crossarm, not round pipe as I remember.

This is an older style of banana tower.
Picture is from our chairlift gallery.
This particular tower was installed September 2, 1980 at Mt. Rose Nevada.
The lift is named Lakeview but has no view of any lake.

Ah yes, you are correct. I had to look at the photos again.

As someone who has skied at Mt. Rose all of his life, this is tower 16 and there is a dramatic view of Lake Tahoe to the southwest as one crosses this tower to the unload station (which follows this tower).
