Beschreibung
Zusammenfassung:	The present invention is directed to a method of controlling a safety apparatus of a construction machine that includes a key switch, a parking switch, an FNR switch, a pilot cutoff solenoid valve, a pilot cutoff switch and a vehicle controller, the method including: applying a power to the construction machine when a key switch operation of a worker is input; receiving operation signals of the parking switch, the FNR switch, and the pilot cutoff switch; determining whether operation states of the parking switch, the FNR switch, and the pilot cutoff switch satisfy predetermined conditions; and controlling the construction machine to be available for the start-up when the predetermined conditions are satisfied. The predetermined conditions are that the parking switch is operated to be on so that a parking brake is operated, the FNR switch is operated to select a neutral so that a traveling direction of the construction machine is in a neutral state, and the pilot cutoff switch is operated to be on so that the construction machine is in a pilot cutoff state. According to the safety apparatus of the construction machine and a controlling method thereof, safety accidents that may occur during the start-up of an engine or during the operation of the construction machine can be effectively prevented.
