The invention provides a rotary lifting appliance suitable for double-crane lifting. The rotary lifting appliance comprises a balance beam. At least two lifting points are formed below the balance beam. The rotary lifting appliance is characterized in that distribution beams are further arranged above the two ends of the balance beam, the middles of the distribution beams are provided with vertical distribution beam through holes, and vertical shafts penetrate through the vertical distribution beam through holes; one end of each vertical shaft is provided with a first lifting appliance body, and the other end of each vertical shaft is connected with the balance beam through a second lifting appliance body; the two ends of each distribution beam are provided with a first distribution beam lifting point and a second distribution beam lifting point. According to the rotary lifting appliance, the distribution beams are arranged and connected through the vertical shafts, so that the lifting weight is reasonably distributed to first walking trolleys, second walking trolleys and third walking trolleys of two portal cranes through the distribution beams; and besides, the vertical shafts and the distribution beams are in clearance fit, the distribution beams can rotate freely, and the lifting requirements of the positions of the walking trolleys and hooks of various portal cranes are met.
