The invention discloses an anti-explosion electric single beam crane. The anti-explosion electric single beam crane comprises an anti-explosion electric block, a metal structure bridge frame and a cart running mechanism; fixing supports are arranged at the two ends of the metal structure bridge frame, the cart running mechanism is arranged on the fixing supports, and a guide rail is installed at the bottom end of the metal structure bridge frame; the upper end of the anti-explosion electric block is connected to the guide rail in a sliding manner through installation of a pulley body, and the cart running mechanism and the anti-explosion electric block are each provided with an anti-explosion electric control system; and the bottom end of the metal structure bridge frame is further provided with an electric block protection support, the electric block protection support is provided with a plurality of waved fulcrum bars connected in an intersected manner, and small pulleys are arranged at the positions of intersecting points of the fulcrum bars in a connected manner and are connected to the guide rail in a sliding manner. By means of the above manner, the stability of the crane can be guaranteed, the waved electric block protection support is connected to one end of the anti-explosion electric block, and the stretching stress of the anti-explosion electric block is improved.
