Many ski areas are in similar situations with aging lifts nearing the end of their functional lifespans.
If one is old enough, they can recall the ski area expansion boom of the 80's. Those lifts are now +/- 40 years old , and then add in the high speed lift revolution which basically began the the mid/late 80's and had a bunch of machines installed by the mid 90's. Not only are those machines now 30-40+ years old, but since at the time they were "new technology" the industry was hoping that their lifespan would be similar to a fixed grip (call that say 50 years as a benchmark number), but now its seeming like those machines have a functional, dependable lifespan more in the 30-35yr range.
Put those 2 things together, and there are LOTS of lifts at ski resorts across the country, that are either in, or will be in, that window where the cost to replace may very well be more reasonable that the likely costs of significant repairs/maintence and questions of reliability as well of the older machines going foreward
