履带式吊管机的吊臂是其施工过程中的主要受力部件,按照相关标准,DGY40型吊管机配置6.5m吊臂,DGY70型吊管机配置7m吊臂,DGY90型吊管机配置7.5m吊臂。上述各型吊管机也可根据客户施工需要配置加长吊臂。最近,国外客户要求我公司为其2009年购买的2台DGY70型吊管机制作2根长度为11m的吊臂,其连接尺寸要与原机长度为7m的吊臂通用。我公司此前没有制作过11m加长吊臂,为此公司技术中心立即组织了技术攻关,
Crawler pipe crane crane is the construction process of the main force components, according to the relevant standards, DGY40 type pipelayer configuration 6.5m boom, DGY70 type pipelayer configuration 7m boom, DGY90 type pipelayer configuration 7.5m boom. The above types of pipelayer can also be configured according to customer needs to extend the long boom. Recently, foreign clients asked our company to manufacture 2 jibs of 11m in length for two DGY70 pipelayer purchased in 2009. The connection size should be common with the jib of 7m in length. My company had not produced 11m longer jib, for which the company’s technology center immediately organized a technology research,
