Hybrid electric power source device for crane and method for controlling hybrid electric power source device for crane

摘要

Even when hayeoteul load is rapidly increased, the hybrid crane capable of preventing the deterioration of the fuel economy of the engine generator provides a control method for a hybrid power supply for the power unit and a crane. An engine generator 10 and a power storage device 40, the power storage device 40 and the power unit for a hybrid engine generator having a crane control apparatus (2) for controlling (10) (1), the controller (2 ), the charge pressure to obtain the engine power based on the required power and the charge electric power of power storage device 40 for supplying electric power to an external calculating unit (2a) and a burden borne engine power calculated by the power calculating unit (2a) calculating the number of the output torque and rotation on the basis of, and an instruction signal transmitting section (2b) for generating a torque command signal and the rotation speed command signal.
