A lifting tool enabling a container to overturn in the air relates to a lifting tool which enables a container to overturn in the air so that discharging of goods of an open-top container or a bulk container is convenient when the container is being hoisted. The lifting tool enabling a container to overturn in the air is composed of an outer bracket 4 and an inner bracket 3, wherein the outer bracket is composed of a horizontal top frame, an end-frame and a V-shaped end vertical frame connected together, and the inner bracket is composed of horizontal end-frames, a side frame and an n-shaped top frame connected together. Two short shafts in the same horizontal axis are installed on the outer end face of the two horizontal end-frames of the inner bracket and are supported in bearings which are installed in the bottom hole of the end vertical frame of the outer bracket. The inner bracket can rotate flexibly in the outer bracket. The lifting tool enabling a container to overturn in the air has the advantages of reasonable structure and capability of overturning the container by 180 degrees to pour goods at a fixed place without re-transportation, reloading and re-charging, reducing contacting space and time of the goods with the outside and pollution to the environment, increasing working efficiency, and being widely applied to bulk containers to load or unload goods.
