The invention provides an aircraft hoisting appliance and belongs to the technical field of structural design of aviation ground equipment. The aircraft hoisting appliance is used for hoisting work in the aircraft production and installation processes. A hoisting beam body is fixedly connected through hoisting beam connectors to be of a closed framework structure. Hoisting bolts are of an integrally formed structure with one ends of threaded rods fixedly connected with lugs. The hoisting beam connectors of a hoisting beam are fixed to the hoisting points through slings, the hoisting beam connectors are connected with the hoisting bolts through the slings, and the hoisting bolts are in threaded connection with an aircraft body of an aircraft. The aircraft hoisting appliance reduces the bending moment of accessories of the hoisting beam due to the characteristic of plane stress of a triangular truss; the additional bending moment of the hoisting points of the aircraft body is eliminated through the hoisting bolts with corners, the stress level of the hoisting area structure of the aircraft body structure and the hoisting appliance is reduced, the design weight of the aircraft body structure and the hoisting appliance is reduced, and the safety of the aircraft body hoisting process and the aircraft body hoisting portability are improved.
