The present invention relates to a steering device for heavy equipment using a joystick to supply hydraulic pressure to left and right rollers installed on a driving wheel of heavy equipment. A load detection signal path of an orbital valve that supplies the hydraulic pressure supplied from a preceding valve to a left-hand roller or a right-hand roller is connected to a proportional valve to control an on-off operation of the proportional valve so that the on-off valve of the proportional valve is closed to block the hydraulic pressure supply by operating the joystick while the steering wheel that drives a first direction switching valve of the orbital valve is operated. By simplifying a technical configuration of the steering device using a joystick, the time and cost required to manufacture the steering device can be reduced.

    본 발명은, 중장비의 구동휠에 설치되는 좌현실린더 및 우현실린더에 유압을 공급하는 조이스틱을 이용하는 중장비용 조향장치에 있어서, 선행밸브로부터 공급되는 유압을 상기 좌현실린더 또는 상기 우현실린더 측으로 공급하는 궤도밸브의 로드감지신호유로가 비례밸브에 연결되어 상기 비례밸브의 온오프 작동을 제어하므로 상기 궤도밸브의 제1방향절환밸브를 구동시키는 스티어링휠이 조작되는 동안에 상기 비례밸브의 온오프밸브를 폐쇄시켜 상기 조이스틱의 조작에 의한 유압공급을 차단하는 것을 특징으로 한다.
