Zusammenfassung: | Disclosed is a stacker crane with an electric fall arrester, which can prevent damage to a product or an accident. The stacker crane with an electric fall arrester according to the present invention comprises: a mast to which a lifting-up-and-down carriage, in which distribution object is seated, is connected to be movable upward and downward; a fall arrester unit that is provided in the lifting-up-and-down carriage and is provided to enable an operation between a normal situation in which upward and downward movements of the lifting-up-and-down carriage are possible and an emergency situation of preventing a fall of the lifting-up-and-down carriage when a wire or belt connected to the lifting-up-and-down carriage is broken down; a breakdown detection sensor unit that detects a breakdown of the wire or belt connected to the lifting-up-and-down carriage; and a fall arrest control unit that is electrically connected to the breakdown detection sensor unit and the fall arrester unit to control the fall arrester unit so that the fall arrester unit is operated in the emergency situation of preventing a fall of the lifting-up-and-down carriage when the breakdown detection sensor unit detects the breakdown of the wire or belt.
전기식 추락방지장치를 구비하는 스태커 크레인이 개시된다. 본 발명에 따른 전기식 추락방지장치를 구비하는 스태커 크레인은, 물류품이 안착되는 승하강 캐리지(carriage)가 업/다운(up/down) 이동 가능하게 연결되는 마스트; 승하강 캐리지에 마련되며, 승하강 캐리지의 업/다운(up/down) 이동이 가능한 정상상황과, 승하강 캐리지에 연결된 와이어나 벨트가 파단되었을 때 승하강 캐리지의 추락을 방지하는 비상상황 사이로 동작이 가능하도록 마련되는 추락방지유닛; 승하강 캐리지에 연결된 와이어나 벨트의 파단을 감지하는 파단감지센서유닛; 및 파단감지센서유닛과 추락방지유닛에 전기적으로 연결되어 파단감지센서유닛에서 와이어나 벨트의 파단을 감지한 경우 추락방지유닛이 승하강 캐리지의 추락을 방지하는 비상상황으로 동작하도록 추락방지유닛을 제어하는 추락방지제어유닛을 포함한다. |
