Abstract

본 논문에서는 고소작업에 가장 널리 사용되고 있는 차량 탑승형 고소작업대의 재해사례분석을 통해 예방대책을 제안하였다. 높은 위치에서의 고소작업은 사고가 발생한 경우 치명적인 인명사고로 이어지기 때문에 이에 대한 안전 대책이 더욱 절실하다. 이에 고소작업 중 발생하는 여러 가지 유형의 사고에 대한 원인을 분석하여 유형별 안전대책을 제시하고, 나아가 사고를 줄일 수 있도록 관련법규의 제정 또는 개정안을 제안하였다. 본 논문에서는 고소작업대의 사고유형을 크게 4가지로 분류하였다. 첫째 와이어로프 구동시스템 불량, 둘째 허용 작업반경 초과로 인한 전도 및 붐 파손, 셋째 턴테이블 불량, 넷째 아우트리거 불량으로서, 가 유형별 사고사례를 분석하고 안전대책을 제시하고, 현행 규정상 고소작업대의 운전 조종에 관한 아무런 규정이 없어서 고소작업대의 운전 조종에 관한 교육 및 자격증 신설을 제시하였다. 그리고 증가하고 있는 안전사고의 예방을 위해 고소작업대의 안전인증 및 안전검사 기준을 강화하는 정책에 발맞추어 법규 개정을 위한 기초자료를 제시하고자 하였다. 본 연구 결과가 실무에 적용된다면 고소작업대로 인한 사고를 크게 줄일 수 있을 것으로 기대된다.

In this paper, we analyze various cases of accidents caused by vehicle-mounted MEWPs(mobile elevated work platforms) which are most widely used for the high position level works, review the safety improvement measures for each of them, and propose basic data for the revision of related laws. The accidents by MEWPs were caused by the high level of works, which lead to fatal personnel accidents, so the measures for safety must be thoroughly carried out and the obligatory regulations by the related laws must be strictly observed. In this paper, we classify the cases of accidents at the workshop as 4 representative types and propose measures and remedies for them. According to the current regulations, it is possible to prepare for the accidents such as the wire rope breakage by switching to the all-chain drive method which does not have a daily use time limit instead of the wire rope drive method which is widely used at present. Also, it is suggested to add the daily use timetable to the nameplate attachment duty item according to the driving class.
