The invention discloses a gantry crane double-speed motor control system which comprises a handheld remote control transmitter, a wireless receiver installed on a gantry crane, a relay assembly used for controlling a double-speed motor and a three-phase alternating current contactor assembly. The output end of the wireless receiver is electrically connected with the input end of the relay assembly, the output end of the relay assembly is electrically connected with the input end of the three-phase alternating current contactor, and the output end of the three-phase alternating current contactor is electrically connected with the input control end of the corresponding double-speed motor. The relay assembly comprises a lifting relay control assembly, a walking relay control assembly and a variable amplitude relay control assembly. The output end of the wireless receiver is electrically connected with the input end of the lifting relay control assembly, the input end of the walking relay control assembly and the input end of the variable amplitude relay control assembly. The device is reliable in operation and simple and convenient to operate.
