TSG Q7001—2006《起重机械制造监督检验规则》(以下简称《规则》)中关于起重机械主要受力构件是指“主梁、主副吊臂、主支撑腿、标准节”。而主梁是构成桥门式起重机械的重要受力部件,其质量的优劣将直接影响到整台起重机的使用寿命及是否能正常运行,所以在主梁的制造过程中,必须对其重要环节进行严格控制。根据《规则》的规定,对构成主梁隐蔽件的检验属A类项检验,隐蔽件在封闭前须由监检人员到达现场检查合格,并由监检人员对制造过程中形成的报告和记录进行签字确认后,方可流转至下道工序。
TSG Q7001-2006 “Lifting Machinery Manufacturing Supervision and Inspection Rules” (hereinafter referred to as “the Rules”) on the main mechanical components of the crane means “the main girder, main jib, main support leg, standard section ”. The main beam constitutes an important force components bridge crane, its quality will directly affect the quality of the entire crane’s service life and whether it can operate normally, so the main beam in the manufacturing process, it must be its Important aspects of strict control. According to the “Rules”, the inspection of hidden parts forming the main beam belongs to the category A inspection. Before the closure, the hidden parts shall be inspected by the inspectors and qualified by the inspectors. The inspection personnel shall report and record the formation of the hidden parts in the manufacturing process After signing the confirmation, can be transferred to the next process.
