Dr. NO wrote:Did Sugarloaf with actual temps of -22, wind chill at -80. They finally closed because the upper lifts, including the T-Bar, closed down due to mechanisms freezing up. I could see Wildcat with the same problem, sub zero temps and wind chills exceeding the level the equipment can handle. Also, more isolated than other areas so why keep the place open for the 10 people that showed up for the day.
I think a lot of us have skied in -20 to -25 below. (Air temp) I know I have. All the lifts seemed to work fine. FYI wind chill does not affect machinery, only the air temp does. Wind chill affects the rate of cooling, but the ultimate temperature the machinery cools to is still the ambient temperature. Having driven a car at 40 below, I can tell you weird stuff started happening at sub 30 below. Grease froze. Rubber no longer flexed. Brittleness of some materials went through the roof. With all the rubber tires on a detach, I wonder what the lower limit is for them to operate.
