根据国家相关规定,起重机制造许可包括产品型式试验和制造单位许可。产品型式试验的制造许可的程序为:申请—受理—型式试验—备案—公告;制造单位许可程序为:申请—受理—型式试验—鉴定评审—审查发证一公告。由此可见,起重机制造许可过程中型式试验是起重机制造许可的重要环节和必要条件,同时它也决定着制造许可证的最终许可范围。为此,现在对起重机型式试验的要求与以往按推荐性标准规定的型式试验要求发生了重大的变化。从目前情况看,很多制造企业对此了解甚少,从我单位进行的桥门式起重机型式试验来看,也发现了许多问题,造成一次通过率极低,整改时间偏长(有的需要几个月),有的甚至无法整改导致 According to the relevant state regulations, crane manufacturing license includes product type testing and manufacturing license. The procedures for manufacturing license for the type test are: application - acceptance - type test - filing - announcement; manufacturing unit permitting procedures: application - acceptance - type test - accreditation review - examination and certification of a public notice. It can be seen from the above that the type test in the process of crane manufacturing license is an important link and necessary condition for crane manufacturing license and at the same time it determines the final permit scope of manufacturing license. For this reason, the requirement of type test of the crane now and the type test requirement of the past according to the recommended standard have undergone major changes. Judging from the current situation, many manufacturing enterprises have little understanding of this. From the type tests carried out by our unit on the bridge crane, many problems have also been found, resulting in extremely low passing rates and long rectification time (some require a few Months), and some can not even lead rectification
