A safety protection device for preventing a portal crane from falling belongs to the technical field of safety protection of portal cranes and comprises a main beam track and a trolley on the main beam track, and four groups of main beam end supports and trolley end supports are symmetrically mounted at two ends of the main beam track and two ends of the trolley respectively. A plurality of falling protectors are arranged between each group of corresponding main beam end bracket and trolley end bracket, and two ends of each falling protector are respectively connected with opposite surfaces of the main beam end bracket and the trolley end bracket. The safety protection structure is arranged on the premise of not influencing the operation of the trolley of the gantry crane, so that the purpose of intrinsic safety is achieved, the great hidden danger of high-altitude falling faced by mounting, overhauling, checking and monitoring operators of the gantry crane is eliminated, and the operation safety is improved.
