초록

본 연구에서는 크레인 작업시 발생하는 재해발생 사례를 토대로 호이스트의 중량물 이탈 방지에 대한 연구를 수행하였으며, 안전고리의 결합으로 구성된 종래의 체결방식을 벗어나 구조물의 무게에 의한 자동 체결 및 결합 방식의 후크 및 특수목적을 가진 X-jog를 설계 및 제작하여 현장에 적용하고자 하였다. 주요 기구부의 3차원 상세설계와 구조해석을 통해 Safety Hook와 X-jog의 미소변형과 허용응력 이하의 구조안정성을 확인하였으며, 안전율은 일반적인 구조설계시 고려되는 안전율 1.2를 상회하는 평균 1.5를 나타냄을 확인하였다. 따라서, 본 연구에서의 Safety Hook와 X-jog는 구조물이 호이스트와 크레인에 부착되어 운용되어질시 구조적 안정성은 충분할 것으로 판단된다.

In this study, we performed a study on prevention of the escape hoist heavy objects on the basis of the case of a disaster occurring during crane operations. A safety hook of the automatic fastening and coupling method by the conventional coupling method, the weight of the outside consisting of a combination of a safety ring structure was designed and manufactured. The main mechanism three-dimensional detail design and structural analysis confirmed the structure and stability of small strain than the allowable stress of the Safety Hook with X-jog through. Safety factor was confirmed to represent the average 1.5 to 1.2 higher than the safety factor to be considered in the general design structure. Therefore, Safety Hook and X-jog in the present study is to be operated upon structural stability is a structure attached to the hoist and crane are considered sufficient.
