The purpose of the present invention is to provide a safe locking apparatus for a four-post type lift, which improves safety by preventing a sudden drop of boarding trays when a wire is expanded or cut, and durability by reducing an impact load applied to a locking bar. More specifically, the four-post type lift comprises: four pillars (1) on which latching grooves (3) are formed; a pair of boarding trays (4) installed between the pillars (1); a pair of horizontal bars (5) which connect the boarding trays (4); brackets (6) arranged on end parts of the horizontal bars (5); and a wire (8) whose one end part is connected to upper parts of each of the pillars (1), and the other end part is connected to a cylinder. In addition, the safe locking apparatus for a four-post type lift, which is installed on the brackets (6) to prevent a sudden drop of the boarding trays (4), comprises: a sudden drop preventing member (10) including a roller mounting part (11) whose base end is coupled to the bracket (6) by a rotary shaft (15a), wherein a roller is mounted on a front end, a locking bar (14) oppositely extended with respect to the rotary shaft (15a) to be inserted into the latching groove (3), and eccentric segments (12a, 12b) protruding from the base end of the roller mounting part (11) to be eccentric at the rotary shaft (15a); and an elastic body which elastically pressurizes the roller mounting part (11) for pressurization of the wire (8) by the roller (21) toward a pulley (7).

    본 발명은 걸림홈(3)이 형성된 4개의 지주(1): 지주(1)들 사이에 설치된 한 쌍의 탑재대(4); 이 탑재대(4)를 서로 연결하는 한 쌍의 수평바(5); 이 수평바(5)의 단부에 구비된 브래킷(6); 및 상기 각 지주(1)의 상부에 일단부가 연결되고 타단부가 실린더에 연결된 와이어(8);를 포함하는 4주식 리프트에서, 상기 브래킷(6)에 설치되어 탑재대(4)의 급강하를 방지하는 안전 록킹장치로서, 선단에 롤러(21)가 장착되고 기단이 회동축(15a)에 의해 브래킷(6)에 결합된 롤러장착부(11)와, 상기 회동축(15a)을 중심으로 대향연장되어 지주(1)의 걸림홈(3)에 삽입되는 록킹바(14)와, 상기 회동축(15a)에서 편심되도록 롤러장착부(11)의 기단에서 돌출된 편심세그먼트(12a,12b)를 포함하는 급강하차단부재(10); 및 상기 롤러(21)가 와이어(8)를 풀리(7)쪽으로 가압하도록 롤러장착부(11)를 탄성가압하는 탄성체(20);를 포함하여 구성된 것을 특징으로 하는 4주식 리프트용 안전 록킹장치이다.
