Why does the cable car and ski lifts shut down in strong winds?

Skiers and boarders have noticed that when the wind is lifted, lifts and ski lifts are shut down, although for some it is only a light wind. JP Ski Resorts of Serbia has provided an explanation of when and why there are closing of lifts and ski lifts in the wind …

“Dear skiers and boarders, during periods of high winds, we are forced to exclude certain lifts and ski lifts from use. Although it sometimes happens that the subjective feeling is such that the wind does not blow too hard, there are devices that infallibly take care of our safety. An integral part of each cableway is the device for measuring the speed and direction of the wind, which is usually located in places where wind gusts are strongest, and most often it is on the last pole of the cable car.

Wind is the only and main cause that affects the safety of a cable car during its operation. Why is this so?

Wind gusts swing the cable car seat and tow lifts. For a cable car, critical gusts of 18m/s and higher are critical, while for a ski lift, speeds of 12m/s or higher are critical. When the wind reaches such high speeds, it swings the seat and towing devices and risks the rope slipping off the roller and causing an accident. In certain lifts, when the wind is extremely strong, when gripping the seat grip on the tow rope, there is a potential for serious damage to the rope and for the seats to slip while driving.

Therefore, ski lifts have devices for measuring the speed and direction of the wind, which indicate that there is a risk of using the ski lift or ski lift. When this happens, the employees of the ski centers are obliged, in accordance with the applicable procedures and the law, to switch off installations and wait for favorable weather conditions for re-commissioning due to the safety of the skiers, their safety and the safety of the equipment.
Thank you for your understanding!” – JP Ski resorts of Serbia
