The invention relates to an electric block type double-rail and single-main-beam crane. The electric block type double-rail and single-main-beam crane comprises a main beam. An upper wing plate is welded to the top of the main beam. Webs are welded to the lower surface of the upper wing plate. Traveling rails are arranged at the lower ends of the webs. An upper wing plate strengthening plate is welded between the upper wing plate and the webs. Web strengthening rib plates are welded between the upper wing plate strengthening plate and the webs. An electric block is installed in the main beam and connected with an electric block base. A trolley frame is connected with the lower portion of the electric block base. The trolley frame is provided with walking devices which are internally provided with walking wheels. The walking wheels are connected with drive motors, and the electric block is connected with a pulley block. The pulley block is connected with a lifting hook. Buffering devices are arranged at the front end and the rear end of the trolley frame. Limiting devices are arranged at the lower portions of the front end and the rear end of the main beam. The electric block type double-rail and single-main-beam crane has the beneficial effects of being reasonable in design, simple in structure, convenient to detect and maintain, large in lifting height, good in lifting performance, safe, reliable, stable in operation, long in service life and high in working efficiency.
