YD30型电动凿岩机由宜春风动工具厂在天水风动工具研究所和O2单位的协助下于1973年11月完成设计并试制出样机五台,其中一台样机在中硬岩石上凿孔1500米,于1973年12月完成工业试验并进行了鉴定定型。 YD30型电动凿岩机是国防、工业建设及农田水利事业中迫切需要的一种新产品。主要用于钻凿各种不同角度的炮眼,凿孔深度最大可达4米。本机特别适用于工作地点分散、交通不便、搬迁频繁的场合。
YD30-type electric rock drill Yichun pneumatic tools factory in Tianshui pneumatic tools Institute and the help of the O2 unit in November 1973 to complete the design and trial production of five prototypes, one of the prototype in hard rock perforated 1500 meters , Completed the industrial test in December 1973 and carried out the identification of stereotypes. YD30 electric rock drill is a new product urgently needed in national defense, industrial construction and farmland water conservancy. Mainly used for drilling all kinds of different angles of the blasthole, drilling depth of up to 4 meters. This machine is particularly suitable for decentralized workplace, traffic inconvenience, relocation occasions.
