본 연구는 건설현장에서 사용하고 있는 타워크레인에 대한 검사기관의 검사결과를 토대로 위험성과 중요도를 미리 검토하고 분석하여, 상호간의 검사 기준에 대한 판정기준을 정립하고 검사능력을 UP-Grade 시킬 수 있는 기회로 활용하기 위한 방안으로, 적절한 평가방법을 도입하여 객관적인 평가 모텔을 제시하는데 목적이 있다. 타워크레인은 건축물 또는 구조물 등, 건설현장에 설치되어 짧게는 2~3개월부터 2년 남짓 동안 지상에서 20~150M 이상 높은 곳으로 건설자재와 중량물 등을 실어 나르는 기계장치로, 건설 현장에서는 없어서는 안될 중요한 설비이다. 그러나 설치해서 사용하는 기간이 짧고, 건설 현장의 기술자들이 타워크레인에 대한 전문 기술력이 부족하여 체계적이고 정량적인 안전관리가 이루어지지 않고 있다. 이러한 문제점을 해결하기 위해서 전문가들의 지식과 경험을 바탕을 한 지식기반기법과 타워크레인에 적용 가능한 RBI절차 연구의 일환으로 정량적 위험우선순위를 FMEA기법을 활용하여 RPN을 적용시켜 보았다. 일반적인 RBI 80/20 Rule을 적용시켜 보았을 때, 위험도가 높은 부분은 와이어로프, 권과방지장치 및 브레이크와 권상감속기 등으로 나타났다. 하지만, 아직 타워크레인에 대한 위험분석이 제대로 이루어지지 않아 미흡한 부분이 많지만, 본 연구를 시작으로 좀 더 경험과 지식이 풍부한 전문가들이 나서서 중요 정보를 공유하고 data base화 하여, 타워크레인에 대한 활발한 RBI 기법의 보완과 지속적인 연구개발이 필요하다.

The purpose of this study is to suggest objective evaluation model as a plan to utilize as opportunity in establishing judgment standard of mutual inspection criteria and to upgrade inspection ability by reviewing and analyzing level of danger and importance in advance based on inspection results of inspection institutions regarding tower cranes used in construction fields. Tower crane is a mechanical device transporting construction supplies and heavy materials to places over 20~150M high from the ground for the period ranging from a short time of 2~3 months to two years after being installed in construction sites in vicinity of buildings or structures and is an important facility indispensable for construction sites. However, since use period after installation is short and professional technical ability of technicians working on-site about of tower crane is poor, systematic and quantitative safety management is not carried out As a part of researches on procedure of RBI(Risk Based Inspection) possible to apply to Knowledge Based System based on knowledge and experiences of experts as well as to tower cranes for solving these problems, quantitative RPN(Risk Priority Number) was applied to RPN utilizing technique of FMEA(Failure Mode and Effect Analyses). When general RBI 80/20 Rule was applied parts with high level of risks were found out as wire rope, hoist up/down safety device, reduction gear, and etc. However, since there are still many insufficient parts as risk analyses of tower crane were not established, it is necessary for experts with sufficient experiences and knowledge to supplement active RBI techniques and continuous researches on tower cranes by sharing and setting up data base of important information with this study as a starting point.

제안 방법
proper evaluation method. In order to secure objective basic data, over two HQs of con耳/nies were designate in multiple number among inspection institutions designated by Ministty of Labor out of domestic construction companies and self inspection was carried out regularly once per each three months and this study was progressed with result2) of amlyses of self inspection data(January 2003~December 2008) conducted for six years with the objects of three companies.
In this study, evaluation standard regarding mutual insjection standard was established with the objects of results of inspection of tower cranes in constniction fields and quantitative evaluation was carried out as a plan to utilize as an opportunity to upgrade inspotion capability one step higher. And by sueesting universal evaluation model of dangers, it was intended to use as an objective measurement scale,
In this study, status of failure as results of regular inspection of tower cranes(Year 1999~2004)'°)conducted by KOSHA(Korea Occupational Safety & Health Agency) for enhancing objectivity of results of analyses and result data of self inspection(January 2003~December 2008) conducted by an inspection institution KIT(Korea Inspection Technology) designated by Ministry of Labor were analyzed and RPN was calculated using FMEA technique for deciding evaluation index per each evaluation 窗ctor.
This study reviewed, in advance, dangers of tower cranes used in construction fields and applied grades of dangers using FMEA technique for qualitative danger order as a part of reseech on RBI procedure possible to apply to tower facilities. Parts with hi曲 level of danger apjeared in coiling prevention device, prevention device of excessive load, wire rope, and coil™ ing decelerator.
que, which can review potential danger in more efficient and relatively feter time m advance than other techniques, was intr(xiuced and ranking of danger necessary for carrying out RBI of tower cranes was evaluated quantitatively by calculating level of inportance from results of analyses.
성능/효과
Level of detection can have various different variables per each item but in this study, it was set by referring to only few(Five) among items judged to make a significant cxmtributicm f쟎 prevention of accidents of tower crane and it was presumed that it is impossible to detect in advance as the measurement scale is higher.
