The invention discloses a double-rail reinforced cart trolley of a gantry crane. The trolley comprises supporting legs, a main beam, a transverse moving mechanism and a hoisting mechanism, wherein the supporting legs are respectively arranged at two ends of the main beam, the transverse moving mechanism is arranged on the main beam, the hoisting mechanism is arranged below the transverse moving mechanism, two rows of slide rails are arranged on the main beam, sliding wheels are arranged on the slide rails, and sliding bulges in sliding fit with the sliding wheels on the slide rails are arranged at the bottom of a base of the transverse moving mechanism. According to the double-rail reinforced cart trolley of the gantry crane, the two rows of slide rails are arranged on the main beam, the sliding wheels are arranged on the slide rails, and the sliding bulges in sliding fit with the sliding wheels on the slide rails are arranged at the bottom of the base of the transverse moving mechanism; a crane trolley slides on the main beam through the two rows of slide rails, so that the weight of objects hoisted by the crane can be increased and the crane can hoist heavier objects; the sliding part cannot be damaged easily, so that the service life of the crane is prolonged; and the structure is simple, the design is novel, and the crane trolley is of a novel reinforcing structure.
