Disclosed is a control method of a lifting apparatus for a highly-mounted device. 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.
