The invention relates to a turnover and multifunctional casting box clamp for an aviation crane, and belongs to the field of turnover multifunctional part clamps. A rotatable hook is mounted on the upper part of a hanging bracket, and travel switches are mounted on two sides of the left lower side of the hanging bracket; an electric rotating mechanism is mounted on the outer side of one end of the hanging bracket, a rotating shaft is connected with the electric rotating mechanism by a flange, a flexible rubber pad is fixed on a clamp plate of the rotating shaft, a hydraulic cylinder is mounted on the inner side of the other end of the hanging bracket, a rotatable clamp plate is mounted on a spindle of the hydraulic cylinder, a flexible rubber pad is fixed on the rotatable clamp plate, and a manual hydraulic device is mounted on the upper part of the hydraulic cylinder. By the turnover and multifunctional casting box clamp for the aviation crane, a box can move to a required place quite conveniently in real time, is overturned to a certain required position and is positioned accurately, and part of functions of a manipulator can be fulfilled. The turnover and multifunctional casting box clamp for the aviation crane is simple and practical in structure, low in cost and high in efficiency.
