Abstract

One aspect of the present disclosure provides a construction machinery including a hydraulic pump, a working device including a boom, an arm, and a bucket, a hydraulic actuator that is operated by a working fluid discharged from the hydraulic pump and includes a boom actuator, an arm actuator, and a bucket actuator that operate the boom, the arm, and the bucket, respectively, a manipulation lever that outputs an electrical manipulation signal in response to manipulation by a worker, a pressure sensor that detects a pressure generated by the hydraulic pump or the hydraulic actuator, and an electronic controller that controls an operation of the hydraulic actuator based on the manipulation signal output by the manipulation lever, wherein, when the pressure detected by the pressure sensor during an excavating operation of the working device is higher than or equal to a boom driving start pressure, the electronic controller controls an operation of the boom actuator to perform boom-up driving.
