The invention relates to the technical field of cranes, in particular to a stable-operation electric hoist portal crane which comprises two supporting plates, lifting mechanisms used for height adjustment are installed on the tops of the two supporting plates, and a horizontal moving mechanism used for horizontal movement is installed between the two lifting mechanisms. A horizontal moving mechanism is installed on the supporting plate, an electric hoist assembly is installed on the horizontal moving mechanism, two braking mechanisms capable of conducting emergency braking are installed on the electric hoist assembly, universal wheels are fixedly installed at the two ends of the bottom of the supporting plate, and lifting mechanisms are installed on the outer walls of the two sides, away from each other, of the two supporting plates. The lifting mechanism comprises an extension plate, the extension plate is fixed to the outer wall of one side of the supporting plate, a containing groove is formed in the top of the extension plate, and positioning holes are formed in the positions, located at the two ends of the containing groove, of the top of the extension plate. The safety of the whole crane can be improved through the arranged electric hoist assembly and the brake mechanism.
