Abstract

Tower cranes have an unstable superstructure, which means that there is a very high risk of accidents. It is necessary to establish preventive measures to ensure the safety of tower cranes at a time when active efforts are being made to reduce safety accidents involving tower cranes. As such, the purpose of this study is to analyze disaster cases to ensure the safety of tower cranes. For this study, 260 cases of tower crane disasters filed with the Korea Occupational Safety and Health Agency from July 2012 to July 2020 were analyzed. Through this analysis, it was found that lifting work was the most common of the work types, at 45.3%; while of the types of disasters, accidents caused by falls were the most common type, at 35.8%. In addition, with regard to the cause of accidents, work method defects was found to be the highest, at 38.8%. In the future, the findings of this study will be used as basic data to guide the establishment of policy to prevent tower crane accidents.

타워크레인은 기초 단면과 비교하여 상대적으로 불안정한 상부구조를 가지고 있어 사고위험성이 매우 크다. 현재 타워크레인 안전사고 저감을 위한 노력이 활발히 이루어지는 시점에 타워크레인의 안전성 확보를 위한 예방대책 수립이 필요하다. 따라서 본 연구의 목적은 타워크레인 안전성 확보를 위한 재해사례 분석 연구이다. 본 연구를 위해 2012년 7월부터 2020년 7월까지 한국산업안전보건공단에 접수된 타워 크레인 재해사례 260건을 대상으로 분석하였다. 그 결과, 작업 공종 중에서는 인양작업이 45.3%로 가장 높게 나타났으며, 재해 형태 중에서는 추락에 의한 사고가 35.8%로 가장 많이 발생하는 것으로 나타났다. 또한, 사고 발생원인은 작업방법 불량이 38.8%로 가장 높은 것으로 확인되었다. 향후 본 연구의 결과는 타워크레인 사고예방을 위한 정책수립에 기초자료로 활용될 것이다.
