The large lifting appliance comprises a rectangular frame body connected with a lifting hook of a floating crane, the end of a cross beam is sleeved with a first U-shaped steel lifting belt used for supporting the cross beam, the inner side of the first U-shaped steel lifting belt is connected with a transverse sliding block, and a transverse adjusting oil cylinder is hinged to the bottom of the cross beam; two longitudinal beams parallel to the length direction of the rectangular frame body are arranged below the transverse beams, the ends of the longitudinal beams are sleeved with second U-shaped steel hanging belts used for supporting the longitudinal beams, longitudinal adjusting oil cylinders are hinged to the bottoms of the longitudinal beams and used for adjusting the distance between the two transverse beams, and a plurality of distribution beams are symmetrically arranged on the top faces of the longitudinal beams. And a plurality of winches are mounted on the distribution beam. The gravity center of the lifting appliance and the gravity center of a lifted heavy object can be located on the same plumb line, and then the stability of lifting operation is greatly improved; the lifting appliance can adapt to lifting tasks of lifting heavy objects with different sizes, and is high in adaptability and good in popularization prospect; according to the invention, multi-hoisting-point hoisting of the large-scale structure can be realized.
