In this paper, a study is done on the rubber-tired container gantry hybrid power crane in order to save energy. Because of the series structure is used in crane hybrid system and working statues of the crane change frequently, a "thermostat + power following "control strategy is used in the hybrid power system based on super capacitor. Based analyzes on the energy flows and system working statues, the super capacitor is adopted different control strategies to avoid the engine starts and stops frequently. The result shows that both the control strategy and the hybrid technology are feasible.
