In Korea construction industry, researches are being conducted to reduce the disasters related tower crane due to the increase of tower crane's usage and accidents continuously. Although the usage amount of remote control tower crane has been increasing recently, the research on remote-control tower crane is insufficient. In this study, the importance ranking of remote control tower crane's accident factors derived by AHP analysis. AHP questionnaire was conducted to engineers (or operators) like construction site engineer, construction manager, safety engineer, and tower crane operator, who have more than 10 years career. The results of AHP analysis reveal that top ranking factor of remote control tower crane's accident is lifting work for materials. Therefore, the high importance factors should be managed, and taken the priority measures for reducing the tower crane accidents by using the results of this research.

국내 사업의 현대화와 아울러 건설에서는 고층화가 이루어지고 있으므로 이에 따른 리프트 및 크레인이 다양하게 많이 사용되고 있고 더욱 사용빈도가 빈번하게 이루어지는 추세이므로 이에 따라 산업재해도 여러 형태로 빈번히 발생이 되고 있는 경향이다. 또한 장치 산업인 산업설비가 발전함에 따라 고압압력용기가 초고압으로 변하여가고 있으므로 이에 따라 발생되는 사고의 영향은 이미 많은 사고 사례에서 볼 수 있는 것과 같이 중대재해가 발생된다. 이에 대한 사고 방지를 위한 검사 기준도 새로운 현실에 적합한 기준개정이 필요하게 되었다. 그러므로 유해·위험한 기계·기구 및 설비의 검사 기준인 리프트, 크레인 및 압력용기 제작기준·안전기준 및 검사기준을 최근 새로운 국내의 실정에 따라 이에 적합하도록 개정이 필요하게 되었다. 특히, 지진 등으로 인한 대형사고를 예방하기 위하여 지진하중 등에 관한 검사항목을 보완한 것에 대한 개정전후의 비용편익분석을 실시하여 개정으로 인하여 관련사업장의 미치는 영향을 확인하고, 편익분석을 함으로서 손익을 정확히 판단하는 것이 기업주나 정책입안자에게 매우 필요하다 하겠다.(중략)

영국의 "기업과실치사법", 캐나다 및 호주의 기업처벌을 강화하기 위해서 형법을 개정하였음에도 불구하고 산업재해 감소 효과는 미미하다. 건설 현장의 불안전한 상태 방치 및 가설구조물에서 강도 높은 안전사고가 다수 발생하고 있다. 본 연구에서는 이러한 안전사고 예방을 위해 안전관리 실명제의 중요도 순위를 전문가 설문으로 도출하였다. 건설현장 전문가를 대상으로 AHP모형을 통해 중요도 분석한 결과 상위계층은 건설기계가 가장 중요하다고 보았으며, 하위계층의 안전시설물 관리에서는 개구부, 건설기계에서는 타워크레인, 관리실명제에서는 "산업안전보건법" 상에 의한 관리, 안전관리조직에서는 CEO의무가 가장 중요하다고 보았다. 안전관리실명제의 기대되는 역할은 중대재해처벌법이 예방에 힘쓰기 보다는 방어에 온힘을 다하느라 예방의 기능이 저하되고 있다. 이러한 역 기능을 바로잡기 위해 안전관리실명제는 중요하다.

현재 건설 현장에서는 유압 굴삭기를 이용하여 굴삭 작업뿐 아니라 비교적 가벼운 물체의 크레인 작업도 병행하고 있다 그러나 국내의 경우 유압 굴삭기를 사용한 크레인 작업은 법으로 못하게 하도록 규제되어 있다. 그럼에도 불구하고 작업 현장에서는 필요에 의해 불법으로 작업을 하고 있으며 이로 인한 사고가 증가하고 있고, 그 비율이 전체 굴삭기 작업 재해의 약 38％에 이르고 있다.(중략)

Poor expertise in equipment operation and installation, coupled with unpredictable natural disaster, usually directly leads to disastrous accidents of large lifting equipment such as tower cranes. For example, 52 tower cranes fell down due to the unstable support in Korea at the attack of Typhoon "Maemi" in 2003, which damaged property and caused loss of life. In high-rise construction projects, top-slewing or luffing-jib tower cranes needs checking the stability of lateral-support in addition to the bottom support such as the foundation. In this study, the optimization algorithm for lateral-support of tower cranes is conducted, which is expected to enhance the structural stability of tower cranes and save the cost in conflict with the safety.

The number of horizontal tower cranes, major hoisting machineries for lifting approximately 50% of entire materials in construction projects, is rapidly increasing, but a number of accidents related to the tower cranes are being continuously occurred in construction sites as well. In particular, telescoping works in the horizontal tower cranes have showed the greatest safety concerns such as falls and collapses. It is due to the fact that tasks inserting a new mast in the space made after raising telescoping cage by fluid pressure and ascending it to the required height in the telescoping works include a series of dangerous factors in safety aspects, and might cause very serious and unexpected accidents in construction sites. The primary objective of this research is to propose two conceptual models for automating the telescoping work in horizontal tower crane and conduct their technical feasibility analyses. In this study, a design concept, a position control system using hydraulic cylinders is suggested as a better alternative for automating the telescoping work. Its potential safety improvement rate compared to the conventional method is also analyzed and presented in this study.

Although various policies have been conducted on safety work of construction equipment such as lifts, tower cranes, and mobile cranes, institutional and managerial problems, and improvement measures, accidents are still not decreasing. This study tried to identify differences in the viewpoints of supervisors, safety managers, and construction machinery operators and to obtain survey data on the awareness and necessity of related safety education. In conclusion, accidents would be reduced when workers received effective training on accurate work methods, safety rules, and recognition and removal of risk factors.

The purpose of this study is to analyze current status and propose improvement scheme of safety management on the heavy construction equipment operation. The research method invloves interview and questionnaire survey for the analysis of practical use status of heavy construction equipment. The results of this study are as fallows: 1) The problem of safety management status on heavy construction equipment operation is surveyed not wearing safety helmet, not keeping work regulations, and not preparing the work before start. 2) Proposed improvement scheme of safety management on heavy construction equipment operation includes strengthening 5 minutes safety education before start, strengthening safety action against falling materials, and strengthening enough preparation before start.

As recent construction projects aim to build higher and bigger buildings, lifting operation is getting increasingly important in construction sites. Accordingly, as tower cranes get higher and higher, disasters involving tower cranes are also on the rise. According to occupational incident statistics of the Korea Occupational Health & Safety Agency (KOHSA), most of such incidents occur in installation, dismantling and climbing phases of tower crane. Therefore, it is essential to develop preventative measures to secure safety of tower crane operations, with critical focus on installation, dismantling and climbing of tower crane. Hence, this research attempts to measure criticality of key risk factors in installation, dismantling and climbing phases of tower crane on construction site and propose necessary safety measures. As a result, conclusions herein will contribute to minimize disasters and incidents involving tower cranes in high-rise building construction sites.
