The present invention relates to a tong-key of a tongs crane for slab transport, and particularly, to a multi-stage separation type tong-key of a tongs crane which allows an upper joint and a lower body of the tong-key to be separated and also allows the lower body to be separated into upper/lower cams, case, etc. by improving a conventional structure of a tong-key formed into a one-piece body by welding so that, as a result, as a replacement work of a tong-key has been simplified, productivity due to reduction of labor and work time has been improved, not only that, industrial disasters can be also reduced due to the simple replacement work. Moreover, the present invention is capable of replacing components and performing an internal inspection of a tong-key in a state in which the tong-key is mounted in a tongs crane, thereby enabling an economical maintenance.

    본 발명은 슬래브 운반용 통스크레인의 통키에 관한 것으로, 특히 종래 용접에 의하여 단일체로 형성된 통키의 구조를 개선하여 통키의 상부 조인트와 하부 몸체가 분리되도록 함과 아울러 하부 몸체 또한 상/하부 캠 및 케이스 등으로 분리되도록 함으로써, 결과적으로 통키의 교체작업이 간소화됨에 따라 노동력 절감 및 작업시간 단축에 따른 생산성 향상은 물론이고 용이한 교체작업으로 산업재해를 줄일 수 있을 뿐만 아니라, 통스크레인에 통키가 장착된 상태에서 통키의 내부점검 및 부품교체가 가능하여 경제적인 유지관리가 가능한 '통스크레인의 다단 분리형 통키'에 관한 것이다.
