The invention discloses a maritime work crane motion control system and a using method thereof. The maritime work crane motion control system comprises a man-machine interaction unit, a control unit, a sensor unit, a control valve group and other function groups, the man-machine interaction unit comprises a touch screen, a control panel and an electric control handle group; the control unit comprises an IO module, a PLC, a proportional valve, a relay and a remote module. The sensor unit comprises an encoder limit switch, a temperature sensor, a liquid level switch, a pressure switch, an angle sensor, a weight sensor and an anemograph; the control valve group comprises a lifting control valve group, a variable amplitude control valve group and a rotary control valve group; in application, a control signal sent by the electric control handle set is collected by the remote module and then transmitted to the PLC, the PLC generates a given signal, detects the system state at the same time, gives a corresponding control curve according to a speed mode and transmits the control curve to the proportional valve, and the proportional valve controls the control valve set to perform corresponding actions. Therefore, according to the design, the operation efficiency is high, and safety is achieved.
