The present invention discloses a safety precaution system for a gantry crane. The safety precaution system comprises displacement sensors, a central processing unit, cameras and an electromagnetic valve, wherein the displacement sensors are respectively arranged on the two support legs of the gantry crane and for transmitting the collected support leg information to the central processing unit, the camera is used for collecting the information of the images on the front track and the rear track of the support legs and transmitting the collected image information to the central processing unit, the central processing unit judges the position of the support leg according to the position information of a plurality of the displacement sensors, judges whether the two support legs are positioned in the same horizontal direction, and judges whether the safety hidden danger exists on the track according to the image information collected by the cameras, the electromagnetic valve turns off the power of the gantry crane according to the command of the central processing unit, and when the central processing unit turns off the power of the gantry crane through the electromagnetic valve, the central processing unit concurrently controls the braking system of the gantry crane to compulsively brake so as to achieve the safe production.
