The invention discloses a portable aluminum alloy gantry crane which comprises a main beam, two supporting legs, a lifting appliance and two nylon tensioning ratchet wheels. The main beam is a horizontal cross beam, and the two supporting legs are arranged at the two ends of the lower side of the main beam respectively. Each supporting leg comprises a vertical beam, an inclined strut, two inclined beams and two supporting feet, wherein the upper ends of the vertical beam and the inclined strut are connected with one end of the main beam through first connecting plates, the lower ends of the vertical beam and the inclined strut are connected through second connecting plates, the two inclined beams are located on the two sides of the vertical beam, the upper portions of the two inclined beams are connected with the vertical beam through third connecting plates, and the lower ends of the two inclined beams are connected with sleeves sleeving the two supporting feet respectively. The lifting appliance is installed on the main beam, and each nylon tensioning ratchet wheel is installed on the two corresponding supporting feet. By means of the portable aluminum alloy gantry crane, the self-weight of equipment is greatly reduced, carrying is more convenient, and the transfer efficiency is improved.
