STARTING ASSIST SYSTEM OF CONSTRUCTION MACHINARY
According to an embodiment of the present invention, a starting assist system for construction machinery comprises: an engine for construction machinery; an input unit receiving a key-on signal and a key-off signal of the engine; a hydraulic pump driven by the engine; an actuator driven by a hydraulic fluid discharged from the hydraulic pump; a regeneration valve transferring a hydraulic fluid returned from the actuator and a portion or the whole of a hydraulic fluid discharged from the hydraulic pump to be supplied for regeneration; an accumulator wherein a hydraulic fluid supplied from the regeneration valve is charged; a charging valve which is controlled so that a flow rate can be discharged from the accumulator in case of the key-on signal is inputted in the input unit; and a hydraulic motor driven by a hydraulic fluid discharged from the charging valve. The hydraulic motor is connected to the engine to assist starting of the engine.
