Apparatus for controlling and method for controlling quick-clamping of construction machine

A method of controlling a safety apparatus of a construction machine includes: 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.
