如何挖掘原有厂房的内在潜力,提高吊车起重等级,以少量的投资、最快的速度,满足生产使用的需要,这是当前工厂技术改造中急需解决的一个课题。某厂为生产需要,改变原产品纲领,须将厂房的吊车起重能力由250吨提高到400吨。这项技术改造任务由机械工业部第七设计研究院负责,兄弟院参加,于1980年进行的。他们根据该厂房原结构情况和400吨吊车产品构造特征,提出了吊车改型措施;对厂房的地基进行了复勘并对承重结构的强度和空间刚度进行了实测和核算,最后确定了技术改造措施方案。几年来生产使用的实践证明,这项技术改造既简易又行之有效。
How to tap the inherent potential of the original plant, increase the lifting level of the crane, meet the needs of production and use with a small amount of investment, the fastest speed, this is a subject that urgently needs to be solved in the current technological transformation of the factory. For a plant to change its original product program for production needs, the crane lifting capacity of the plant must be increased from 250 tons to 400 tons. This technical transformation task was carried out by the Seventh Design and Research Institute of the Ministry of Machinery Industry and participated in by the Brotherhood in 1980. Based on the original structure of the factory building and the structural features of the 400-ton crane product, they proposed a modification of the crane; the resurfacing of the foundation of the factory building was carried out and the strength and spatial stiffness of the bearing structure were measured and accounted for, and finally the technical transformation was confirmed. Measures program. The practice of production and use over the past few years has proven that this technological transformation is both simple and effective.
