타워크레인은 아파트, 빌딩 등 고층건물 건설공사에서 가장 많이 이용되는 건설 기계로서 건축물의 높이가 높아짐에 따라 설치·상승·해체 작업이 자주 일어나고 작업 특성상 고도의 기능과 안전관리가 필요한 건설기계이다. 법에서 정한 검사제도에 의해 검사를 시행하고 있음에도 불구하고 해마다 타워크레인에 대한 중대재해가 끊이지 않고 있으며 그로 인한 피해가 가중되고 있...
타워크레인은 아파트, 빌딩 등 고층건물 건설공사에서 가장 많이 이용되는 건설 기계로서 건축물의 높이가 높아짐에 따라 설치·상승·해체 작업이 자주 일어나고 작업 특성상 고도의 기능과 안전관리가 필요한 건설기계이다. 법에서 정한 검사제도에 의해 검사를 시행하고 있음에도 불구하고 해마다 타워크레인에 대한 중대재해가 끊이지 않고 있으며 그로 인한 피해가 가중되고 있는 실정이다.
본 연구에서는 타워크레인의 국내외 검사제도 조사와 타워크레인 검사의 부적합 요인을 분석하고 타워크레인 임대업체에 부적합 원인에 대한 설문조사를 통해 얻은 결론은 다음과 같다.
타워크레인 검사의 부적합이 지속적으로 발생하고 늘어나는 이유는 검사기준이 육안검사가 대부분임에도 임대업체의 정비인력이 부족하여 장거리 출장과 점검시간의 부족으로 검사준비가 소홀하였고 설치 후 자체점검 미실시가 주 원인으로 조사되었다. 타워크레인의 재해예방을 위한 근원적 안전성을 확보하기 위해서 사전검사와 자체검사를 신설, 타워크레인 관리시스템 구축, 건설기계관리법 시행규칙 및 규칙의 별표를 개정, 타워크레인 검사대행자 협의회 구성, 안전성 확보에 도움이 되는 장치 개발 및 보급이 필요하다.
앞서 제시한 제도적, 관리적, 행정적, 교육적, 기술적 측면에서의 근원적 안전성 확보방안을 종합적이고 체계적으로 시행하여야만 타워크레인 검사제도가 개선되고 안전사고를 예방할 수 있을 것이다.

An average of 7.8 workers have died in the past five years due to the use of the tarmac, and this risk is higher than any other hazardous machine used in the industrial field. According to the analysis of the causes of the Tower Crane-related disasters, 78.8 percent of the total installed and disinfected work, 9.1 percent of the daily operations (rescue operations), 9.1 percent of the defects in maintenance inspection, and 1.2 percent of other (natural disasters) This study examined the definition and structure of the Taworrain and compared the domestic and overseas inspection system. In addition, it was intended to prevent safety accidents by analyzing the causes of nonconformities in the last six years and presenting improvement measures to compensate for the problems of the inspection system through surveys on the causes of nonconformities with the trucker. The conclusions resulting from the survey and analysis are summarized as follows: First, in order to secure the fundamental safety of the use phase as an institutional measure, a pre-examination and self-inspection of the truckers should be newly established. Because preliminary inspections are mainly comprised of non-destructive testing, fairness and reliability can be secured only if they are entrusted to an inspector who is registered in a non-destructive testing project. Self-inspection shall be institutionalized every month after installation so that only those qualified by self-inspection personnel can perform the inspection. Such institutional improvements should be implemented first to prevent fundamental safety accidents.
Second, as a management measure, the construction machinery management information system shall be an independent system of the Taworkane to collect and manage data such as the status of installation use, manufacture year, and maintenance record. If this information system is utilized, information can be shared between inspection agents and shall be thoroughly managed by establishing an efficient Tower Crane Management System such as statistical management.
Third, the Schedule of Enforcement Rules and Rules of the Construction Machinery Management Act should be amended as an administrative measure. The list of equipment in Annex 9 of the Enforcement Rules shall be revised to conform to reality, while adding a type report and manual among documents submitted for inspection. Only when these relevant laws are amended can the defects of the inspection be resolved and efficiency increased.
Fourth, it is necessary to form a regular Tower Crane Test Agency organized by the Ministry of Land, Infrastructure and Transport as an educational measure. With the formation of a consultative body, it will play a direct role in the prevention of Tower Crane accidents by enhancing the capabilities of inspectors and improving the quality of the inspection by exchanging information among exam takers.
Fifth, as a technical measure, the government should revise domestic standards and apply them to the project sites by investigating the manufacturing and safety standards of advanced Tower Crane. Although it does not apply to legal standards such as hook cameras and collision prevention devices, it shall be developed and distributed through public-private cooperation to maximize the safety performance of the Tower Crane.
In addition to the five measures mentioned above, user-level measures should be continuously taken to ensure accuracy in analysis of causes of accidents and establishment of countermeasures, including the installation of a Tower Crane, the introduction of a decommissioning qualification system, and the concept. The safety accidents will be eradicated only when continuous research by safety experts is conducted and measures are taken against Taworlane that threatens workers' safety due to the high risk of accidents.
