The invention provides a lifting appliance for lifting a fragmented bent cap. The lifting appliance comprises a frame body, a rope winder and a hydraulic pump station. Longitudinal swing hinge points are arranged at the bottoms of the two sides of the frame body correspondingly, the longitudinal swing hinge points are connected with hanging bases through pin shafts, the longitudinal swing angles are adjusted through longitudinal hydraulic cylinders, the hanging bases are connected with hangers through pin shafts, a transverse swing hinge point is arranged on the upper middle portion of the frame body, the transverse swing hinge point is connected with a connecting base through a pin shaft, the transverse swing angle is adjusted through a transverse hydraulic cylinder, the connecting base is connected with a sling through a pin shaft, the rope winder is arranged at the upper end of the frame body, and the hydraulic pump station is used for driving the longitudinal hydraulic cylinders and the transverse hydraulic cylinder. According to the lifting appliance, the damage and breakage of a prefabricated part caused by local abnormal contact and extrusion during alignment installation can be avoided, and the engineering quality is ensured.
