The invention belongs to the technical field of steel box arch rib installation, and particularly relates to a polygonal steel box arch rib single-hook lifting appliance and a lifting method thereof. A polygonal steel box arch rib single-hook lifting appliance comprises a plane truss, an inclined supporting leg assembly and a transverse main beam assembly, the plane truss is of a frame structure and comprises longitudinal distribution beams, transverse distribution beams and first conversion joints, the longitudinal distribution beams and the transverse distribution beams are arranged in parallel, and the first conversion joints are connected between the longitudinal distribution beams and the transverse distribution beams. The inclined supporting leg assembly sequentially comprises a second conversion joint, a lead screw rotating joint, an inclined adjusting lead screw, an inclined steel pipe and an inclined steel pipe connecting pin from bottom to top, a locking nut is arranged between the lead screw rotating joint and the inclined adjusting lead screw, and the transverse main beam assembly comprises a hoisting bearing beam and a transverse movable hoisting point installed on the hoisting bearing beam. Lifting lugs are respectively arranged at two ends of the lifting bearing beam. The mounting posture of the steel box arch rib can be adjusted under the condition of single-hook hoisting, different angle changes of the arch rib can be adapted, operation is easy, and reliability is high.
