一起流动式起重机倾覆事故的原因探讨

Causes Analysis on Overturning Accident of a Mobile Crane

以一起流动式起重机倾覆事故作为分析对象,通过现场勘查测量与理论计算,对倾覆原因进行具体的技术分析,得出由于关闭力矩限制器致使严重超载,以及无吊装方案、选型不当等原因,是造成起重机整体倾覆的主要原因;并对起重机的制造和使用提出建议。

Taking a mobile crane overturning accident as an analysis object, a detailed technical analysis of the reason of overturning is carried out through site survey measurement and theoretical calculation. It is concluded that closing the torque limiter results in serious overloading, as well as improper lifting scheme and selection, which is the main reason for the overturning of the crane. Recommendations for the manufacture and use of cranes are proposed.
