CONSTRUCTION MACHINE STARTING ASSIST SYSTEM
An exemplary embodiment of the present disclosure relates to a construction machine starting assist system including: an engine of a construction machine; an input unit which receives a key-on signal and a key-off signal of the engine; a hydraulic pump which is operated by the engine; an actuator which is operated by hydraulic oil discharged from the hydraulic pump; a regeneration valve which is switched so that a part or an entirety of the hydraulic oil returned from the actuator and a part or an entirety of the hydraulic oil discharged from the hydraulic pump are supplied for regeneration; an accumulator which is charged with the hydraulic oil supplied from the regeneration valve; a charging valve which is controlled so that the hydraulic oil is discharged from the accumulator when the key-on signal is inputted into the input unit; and a hydraulic motor which is operated by the hydraulic oil discharged from the charging valve, in which the hydraulic motor is connected to the engine and assists in starting the engine.
