浅析轮胎吊大车平衡梁开裂成因及防控

Analysis on the Causes and Prevention for the Balance Beam Cracking of the Tyre Container Gantry Crane

对轮胎式集装箱门式起重机(RTG)(简称轮胎吊)大车平衡梁开裂事故的多种成因进行简要分析。针对轮胎吊跑道梁坡度引起的问题进行描述,并提出采用日常检查平衡梁机械挡块、大车运行变频器参数调整、程序检查排除、智能型大车制动器引入的可能性、大车平衡梁机械加固加强等措施预防管控平衡梁开裂故障。通过分析及管控措施,取得良好的裂纹防控效果。

Made a brief analysis on various causes for cart balance beam cracking accident of the rubber tyredcontainer gantry crane（RTG）. Problems caused by RTG runway beam slope were described,and the preventionmeasures such as daily check balance beam mechanical block,the operation of the inverter parameter adjustmentprogram,checkout,the possibility of introducing intelligent gantry brake,the mechanical balance beam strengthenedcontrolled balance beam crack fault. Through the analysis and control measure,good control effect of crack isachieved.
