The invention discloses a movable and lifting type clothes-airing or object-hanging system of a large-scale life balcony and a controlling method. The system comprises two guiding rails, two movable type clothes-airing or object-hanging mechanisms which are located at the left and right ends of the guiding rails, and a clothes-airing or object-hanging rod capable of being folded, wherein the two movable type clothes-airing or object-hanging mechanisms are capable of moving along the two guiding rails on the top. The movable and lifting type clothes-airing or object-hanging system and the controlling method are applicable to the large-scale life balcony, and movements in horizontal and vertical directions are achieved through a simple structure; compared with an existing device, the integral implement structure is simplified, and the possibility of occurrence of malfunctions in the use process is reduced; during the implementation, firstly the guiding rails are installed on the top of the balcony, the two movable type clothes-airing or object-hanging mechanisms are movably hung on the guiding rails so that the two movable type clothes-airing or object-hanging mechanisms can slide on the guiding rails, and then the clothes-airing or object-hanging rod is tightly screwed on the two movable type clothes-airing or object-hanging mechanisms as a whole so as to achieve a use state.
