Abstract

Purpose: This study aims to propose preventive measures for boom failure accidents in concrete pump trucks by enhancing design and manufacturing quality control and revising periodic inspection standards. Method: Recent mechanical failure accidents in concrete pump trucks were analyzed, focusing on accident characteristics and inspection criteria improvements. Finite element analysis (FEA) from prior studies was reviewed, highlighting the second boom as the most stress-prone component during operation. Result: FEA confirmed that the second boom experiences the highest fatigue stress, making it the most vulnerable. Increasing its material thickness and reinforcing it with steel plates during manufacturing is essential. Additional reinforcements are also recommended for equipment currently in use. Conclusion: Manufacturers should reinforce the second boom's upper section during production. Inspection costs should be adjusted, non-destructive testing mandated, and accountability measures for inspection agencies implemented to enhance safety.

연구목적: 본 연구는 콘크리트 펌프카의 붐대 파단 사고를 예방하기 위해 설계 및 제작 단계에서의 품질관리를 강화하고, 현행 정기검사 기준을 개선할 필요성을 제안한다. 연구방법: 최근 1~2년 사이에 발생한 콘크리트 펌프카의 기계적 결함 사고를 조사하고, 사고의 특징을 분석하였다. 또한 펌프카 장비의 검사 기준 및 조종원의 자격과 기능교육 기준 마련의 필요성을 검토하였다. 붐대의 안전성을 확인하기 위해 선행연구의 구조적 안전성 평가와 유한요소 해석 자료를 재분석하였으며, 특히 2단 붐대가 타설 과정에서 가장 큰 하중을 받아 파손 가능성이 높음을 확인하고 검증하였다. 연구결과: 유한요소 해석 결과, 펌프카는 타설 과정에서 발생하는 진동으로 인해 피로 하중을 받을 수 있으며, 가장 취약한 부위는 2단 붐대임이 확인되었다. 이에 따라 2단 붐대는 제작 단계에서 부재 두께를 증가시키고, 상단부에 철판을 보강하는 것이 필요하다. 또한, 현재 사용 중인 장비에 대해서도 추가적인 철판 보강이 요구됨을 확인하였다. 결론: 펌프카 사고를 방지하기 위해 제조사는 2단 붐대 상단부에 보강판을 부착하는 방안을 설계와 제작 과정에 반영해야 한다. 또한, 정기검사 비용의 현실화와 비파괴 검사의 의무화를 제안하며, 사고 발생 시 검사 기관의 책임을 명확히 하는 제도 마련이 필요함을 제언한다.
