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.
