이동식크레인은 높은 사망률에 기여하는 기계로 최근 6년간(2016~2021) 사고사망사례 중 건설업 2,574건을 분석한 고위험 요인(SIF)정보에서 이동식크레인의 사고는 총 61건의 재해가 발생하였다. 현장의 안전대책에도 불구하고 제대로 활용이 안되고 있다. 본 연구에서는 표준 리스크 평가 지수를 제시하여 사고예방에 기여하고자 한다

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.

As the construction projects become higher, larger and more complex, they become more dangerous, especially vertical transportation activities. So this study analyzed 122 critical accident cases reported to the KOSHA(Korea Occupational Safety & Health Agency) for construction cranes by types of cranes, patterns of accidents and causes. It is expected that the results of this study can be used as useful basic data or material when preparing for special safety education and training for preventing crane accidents.

As buildings become larger, higher and more complex in most construction sites, construction projects have to deal with transportation of more materials, labor and equipment, necessitating more use of construction equipment. Notably, in the high-rise building and plant construction projects mobile cranes are adopted more frequently among different types of construction machinery, which also results in serious industrial accidents relating to the use of crane. To reduce serious industrial accidents involving cranes, researches on its stability is in need. The research herein aims to study how to select sling and lug of mobile crane and review its stability. The research outcomes herein will make considerable contributions to selecting mobile cranes efficiently and ensuring their stability.

타워크레인은 빌딩, 아파트, 교하공간이 높은 교량, 플랜트 공사 등 고소작업이 이루어지는 공사에서 유익하게 사용되는·건설장비이다 타워크레인은 단면에 비하여 그 설치높이가 높아서 매우 세장한 구조물이며, 마스트 상부에 설치되어 있는 상부구조물(타워 해드, 지브, 카운터 지브, 카운터 웨이트, 기계장치 등)의 자중이 매우 크기 때문에 하중균형, 풍하중, 인양하중 등에 아주 민감한 강구조물이다. 따라서 이러한 타워크레인의 특성에 대한 이해의 부족과 안전한 작업방법의 불이행 등으로 인한 사고가 가끔 발생되고 있으며, 타워크레인의 사고는 곧바로 중대재해로 이어지고 있다.(중략)

Purpose: Mobile cranes are machines that contribute to high mortality, and the High Risk Factor (SIF) information, which analyzed 2,574 accidental deaths in the construction industry in the past 6 years (2016~2021), resulted in a total of 61 mobile crane accidents. Despite safety measures in the field, it is not used properly. In this study, we present standard risk assessment indicators that contribute to accident prevention. Method: Through expert interviews, fatal accident case analysis, field analysis, and literature research, we present the standard risk assessment index method of the 4M risk assessment method. Result: As a result of analyzing the risk assessment of eight sites, it was concluded that it cannot make a significant contribution to disaster prevention and should be applied as an improvement measure of the Standard Risk Assessment Index Law. Conclusion: Switching to the standard risk assessment index method at construction sites has been proposed to make it easier for health and safety personnel and workers to use, contributing to the reduction of accidents.

As buildings become higher, larger, and more complex, safety issues for construction workers working at such environments become more important. We analyzed 140 critical accident cases reported to the KOSHA(Korea Occupational Safety & Health Agency) for construction cranes and lifts by types of cranes and by patterns of accidents and causes. By finding out the accident's types and causes, we expect to develop an efficient measure for preventing similar accidents in the near future. The cases will be studied further and reexamined using the FMEA(Failure Mode and Effect Analysis) as a quantitative analysis method.

As buildings become higher, larger, and more complex, safety issues for construction workers working at such environments become more important. We analyzed 83 critical accident cases reported to the KOSHA(Korea Occupational Safety & Health Agency) for construction cranes by types of cranes and by patterns of accidents and causes. There are more number of accidents related to mobile cranes than that related to tower cranes, but the numbers of dead were similar in both cases. The most dominant cause of crane accidents was "fall of materials". We also analyzed the cases of crane accidents using the FMEA(Failure Mode and Effect Analysis) in order to set up a priority for safety management and also to prioritize research and development items relating tower cranes. In the process, we tried to eliminate subjective indexes such as an expert group survey and use objective and quantitative indexes. As a result, it was found that critical crane accidents occurs most during the "lifting and translating" activity.
