Disclosed is a control method of a lifting apparatus for a highly-mounted device, which includes 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 includes (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), it is determined whether the lifting body is normally released downward from the main body by checking whether a weight of the lifting body is applied to the wire rope.
