A control method of a lifting apparatus for a highly-mounted device, the lifting apparatus including a main body at which a hollow drum for winding a wire rope and a driving motor for giving a rotating force to the drum are installed, a lifting body suspended from the wire rope and having a device coupling portion provided at a lower end thereof, and an upper contact point and a lower contact point respectively provided at the main body and the lifting body to make contact with each other when the lifting body ascends and is coupled to the main body by winding the wire rope, the control method comprising: (a) outputting a descending signal in a state where the main body and the lifting body are coupled; (b) determining whether the lifting body is normally released downward from the main body according to the descending signal; and (c) stopping the driving motor or executing the step (a) again when the lifting body is not normally released downward, wherein in the step (b), when a weight of the lifting body is applied to the wire rope so that a guide roll configured to support the wire rope is moved due to the weight of the lifting body to press a limit switch, it is determined that the lifting body is normally released downward, wherein the control method further comprises: (d) outputting an ascending signal in a state where the lifting body is lowered; (e) determining whether the lifting body ascends and is normally coupled to the main body according to the ascending signal; and (f) stopping the driving motor or executing the step (d) again when the lifting body is not normally coupled to the main body; operating the driving motor to give a rearward rotation so that the lifting body is caught by a stopper, after the lifting body is lifted and then stopped; and determining whether the lifting body is normally caught by the stopper by checking whether the weight of the lifting body applied to the wire rope is released; and wherein it is determined that the lifting body is normally caught by the stopper, when the weight of the lifting body applied to the wire rope is released so that the guide roll supporting the wire rope returns and is separated from the limit switch due to the release of the weight of the lifting body. (a) outputting a descending signal in a state where the main body and the lifting body are coupled; (b) determining whether the lifting body is normally released downward from the main body according to the descending signal; and (c) stopping the driving motor or executing the step (a) again when the lifting body is not normally released downward, wherein in the step (b), when a weight of the lifting body is applied to the wire rope so that a guide roll configured to support the wire rope is moved due to the weight of the lifting body to press a limit switch, it is determined that the lifting body is normally released downward, wherein the control method further comprises: (d) outputting an ascending signal in a state where the lifting body is lowered; (e) determining whether the lifting body ascends and is normally coupled to the main body according to the ascending signal; and (f) stopping the driving motor or executing the step (d) again when the lifting body is not normally coupled to the main body; (d) outputting an ascending signal in a state where the lifting body is lowered; (e) determining whether the lifting body ascends and is normally coupled to the main body according to the ascending signal; and (f) stopping the driving motor or executing the step (d) again when the lifting body is not normally coupled to the main body; operating the driving motor to give a rearward rotation so that the lifting body is caught by a stopper, after the lifting body is lifted and then stopped; and determining whether the lifting body is normally caught by the stopper by checking whether the weight of the lifting body applied to the wire rope is released; and wherein it is determined that the lifting body is normally caught by the stopper, when the weight of the lifting body applied to the wire rope is released so that the guide roll supporting the wire rope returns and is separated from the limit switch due to the release of the weight of the lifting body.
