The invention provides a crane extended range type power system, a driving method of the crane extended range type power system and a crane, and relates to the technical field of engineering machinery driving. The crane extended range type power system comprises a chassis engine, a generator, a motor and a conducting ring; the power output end of the chassis engine is connected with the input end of the generator; the output end of the generator is connected with the input end of the conducting ring; the input end of the conducting ring is connected with an external power supply; the output end of the conducting ring is connected with the motor; the engine drives the generator to generate electricity and inputs electric energy to the motor through the conducting ring, and/or the conducting ring inputs electric energy to the engine by being connected with the external power supply; and the motor is suitable for converting electric energy into kinetic energy to drive an execution system of the crane. The advantages of an engine power source and a motor power source are integrated, the chassis engine can drive an automobile to walk and can provide kinetic energy for the generator at the same time, the automobile crane can walk and transition for a long distance, and therefore the energy utilization rate is increased, waste gas emission is reduced, and the obvious energy-saving and emission-reducing effects are achieved.

    本发明提供了一种起重机增程式动力系统及其驱动方法与起重机,涉及工程机械驱动技术领域,包括底盘发动机、发电机、电动机与导电环;底盘发动机的动力输出端连接发电机的输入端;发电机的输出端连接导电环的输入端;导电环的输入端还适于连接外部电源,导电环的输出端连接电动机;发动机驱动发电机发电并通过导电环为电动机输入电能,和/或导电环通过连接外部电源为发动机输入电能;电动机适于将电能转化为动能以驱动起重机的执行系统。本发明整合了发动机与电动机动力源的优势,底盘发动机既可驱动汽车行走,同时能够为发电机提供动能,使汽车起重机既能够长距离行走转场,从而提高了能源利用率,降低了废气排放,具有显著的节能减排效果。
