Disclosed is a lifter with a pneumatic fall arrester capable of preventing accidents and damage to a product. The lifter with a pneumatic fall arrester according to one embodiment of 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 pneumatic fall arrester unit that is provided in the lifting-up-and-down carriage and is provided to enable a pneumatic 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 pneumatic provision unit that provides air pressure to the pneumatic fall arrester unit to allow the pneumatic fall arrester unit to be operated in the emergency situation of preventing the fall of the lifting-up-and-down carriage when the breakdown detection sensor unit detects the breakdown of the wire or belt.

    공압식 추락방지장치를 구비하는 리프터(Lifter)가 개시된다. 본 발명의 일 실시예에 따른 공압식 추락방지장치를 구비하는 리프터(Lifter)는, 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 마련되되 공압으로 동작하는 공압식추락방지유닛; 승하강 캐리지에 연결된 와이어나 벨트의 파단을 감지하는 파단감지센서유닛; 및 파단감지센서유닛에서 와이어나 벨트의 파단을 감지한 경우 공압식추락방지유닛이 승하강 캐리지의 추락을 방지하는 비상상황으로 동작하도록 공압식추락방지유닛에 공압을 제공하는 추락방지공압제공유닛을 포함한다.
