ABSTRACT:
An apparatus monitors the locking of the safety bar of the chairs of an aerial cableway system. A first sensor determines the occupancy of the chairs and a second sensor determines the locking of the safety bar. The sensor output signals from these two sensors are led to a control device, which is enabled to switch the chairlift system off.
