I asked this question on another forum and was told that this was the place to go. I checked FAQs and didn't find this, so if this has been answered, please guide me to the proper place. Thanks.

About how often do they have to be changed?

Is the time shorter for detachables because of the wear-and-tear of attaching and reattaching to the cable?

Is there a formula for cable diameter as a function of cable length that someone would be willing to describe?

Approximately how much per foot does a lift-cable go for?

I can answer a couple of these; there are others who probably know more.

A rope can last twenty years, properly cared for.
A detachable lift actually wears its rope less because the grips never stay in the same place. A fixed grip wears the same spot for six months, and every time it goes around the bullwheel it wears it a little more.
Length and diameter aren't necessarily related. The length of the rope is however long you need it to be, and the diameter depends upon how much load you will be carrying. A double may only need a 1 1/8" rope, while a sixpack can use a 2" or bigger.
I have no idea how much a rope costs as I'm on the installation end and not the purchasing.

Hope this helps.

We're replacing the rope on Catskinner this year. It's 1.5 inch and I believe the cost is $75,000 CDN. Cable length is 2,750 m.

Thanks "Aussierob" and "liftmech".

If I translate Canadian Dollars to US and meters to feet, it would appear that 1.5 inch haul rope is about 6 US dollars per foot.

Are all the Blackcomb Yans 1.5? (Crystal, and Magic)?
