The present invention relates to an aerial work system using a post-rotating device. The aerial work system is able to easily convert working space through a bucket without moving the position of a vehicle or resetting the boom angle through the free movement of the bucket position in the horizontal direction by horizontally rotating a bucket centering on a boom pole with an end bucket in a vertical state. The aerial work system comprises: a swing post part which supports an upper structure; a boom pole which is combined with the swing post part to move to the working position; a bucket which is connected to the boom pole; and a post-rotating device which is installed to the boom pole to allow the bucket to be horizontally rotated centering on the boom pole. The post-rotating device comprises: a combining plate which is fixedly combined to an end in the longitudinal direction of the boom pole; a rotary unit inner fixation shaft of which is fixated to the combining plate and outer rotary shaft of which rotates in accordance with the driving force; and a connecting element which rotates by receiving rotation force from a rotary shaft in an outer side of the rotary unit, wherein the connecting element rotates in accordance with the rotation of the rotary shaft of the rotary unit to horizontally rotate a supporter combined to corresponding connecting element and the bucket centering on the boom pole. |
