The invention discloses a portal crane with an anti-overturning structure, and relates to the technical field of hoisting equipment. The device comprises a main beam, a hanging bracket, an anti-inclination structure, a windproof frame and a windproof shed, supporting legs are fixed to the two sides of the bottom of the main beam, a trolley running mechanism is connected with winding drums through steel wire ropes, the bottoms of the two winding drums are connected with the two sides of the top of the hanging bracket respectively, and the hanging bracket is connected with the supporting legs on the two sides through the anti-inclination structure. A windproof frame is detachably connected to the supporting legs, and a windproof shed is installed on the windproof frame. When the gantry crane is used in the outdoor strong wind weather, the hanging bracket can stably run in the outdoor strong wind weather through the multiple effects of limiting of the anti-inclination structure and the windproof structure, the safety performance is extremely high, the gantry crane is very suitable for being used in the outdoor strong wind weather, the outside of the gantry crane can be protected through the windproof shed, and the safety of the gantry crane is improved. And the protective performance is high, and the use safety of the portal crane is improved.
