The invention discloses a lifting appliance for a crown block and an automatic hooking and unhooking method of the lifting appliance, solves the problem of how to realize automatic hooking and removing of a high-altitude lifting hook, and belongs to the field of lifting hooks. A left lifting plate and a right lifting plate which are parallel to each other are fixedly arranged on the top end face of a vertically-placed lifted box body (2), and the two lifting plates are identical in structure and are both provided with square lifting holes and rectangular through holes; a traditional method that an anti-falling clamping tongue is arranged in an opening of the lifting hook is changed, the anti-falling clamping tongue is replaced by the turning plate, and the movable turning plate is arranged on the outer side of the opening of the lifting hook; the two lifting hooks are connected to the two ends of the triangular frame lifting beam in a lifting mode with the openings facing inwards, so that the triangular frame lifting beam vertically falls or ascends, and automatic hanging connection and automatic separation of the lifting hooks and the upper square lifting holes are achieved through cooperation of the lifting hooks, the turning plates, the square lifting holes and the rectangular through holes. According to the invention, the operation of automatically hanging the lifting hook and automatically releasing the lifting hook on a high and large box body or a high and large plate type transported workpiece which is vertically placed is realized.
