摘　　要：用故障树法对塔式起重机的起升机构“电动机过热”的故障进行了分析,绘制了故障树,并进行了定性和定量分析,找出了系统的薄弱环节,对提高塔式起重机可靠性及设备维修有指导意义。Analyzes the failures-lift-up equipment in ＂motor over - heating＂ of through FTA. Fault trees of lift - up equipment are established and quantitatively and qualitatively analyzed, then the weakest links in the system are obtained. It is instructive meaning towards raising the reliability and maintaining the equipment.

关 键 词：FTA 塔机 电动机过热 定性 定量
