The invention relates to a novel crane synchronous control device. The device comprises two variable frequency motors, two expansion cards, two SEOHO frequency converters, two synchronization cards, and two terminals. Each SEOHO frequency converter is connected to one variable frequency motor, one expansion card, and one synchronization card through signal wires. The two expansion cards are connected through a signal wire. The terminals and the expansion cards are respectively connected through signal wires. The two SEOHO frequency converters are connected through a communication cable.
