Carriers (the chairs) are hung from the cable and held in place with a mechanical grip. The grip functions similarly to a vice and is tightened around the cable to keep the chair from sliding back. A chair gradually slides back a bit each season, which is why lines are often painted on the cable.
How are chair lifts attached to the cable?
Detachable chairlifts are not directly connected to the moving cable. They use grips to clamp onto the cable, which then moves them up the mountain. This allows the chair to slow down for loading and unloading by loosening the grip on the cable (also called rope).
