This Poma Delta triple is one of two main base to summit lifts here.The equipment came used from Ski Rio, New Mexico.Loading area and lift shack.The top terminal.Last tower at the summit.Looking down the lift line.View up from the base area.
I would guess ride quality, they also tended to use more sheaves than if they had been using the standard size ones, allowing a smaller deflection per sheave. I would guess this lift would have used a 10 or 12 sheave assembly if the standard size was used with the smaller sheaves it’s a 16 sheave assembly.

I have never seen Poma ring towers before. The ring tower was the last tower.

Those are “tower guards” by the way. They are commonly used on older Riblets and 80s Poma lifts but they are usually never found on the tube. They are usually on the crossarm: https://skiliftblog.files.wordpress.com/2018/08/img_9770.jpg

Why did Poma of this eara (and others like most Halls) use smaller sheaves for depression and larger sheaves for support?

I’ve wondered that for years, and I work on a twin to this one.
