YG40型导轨式凿岩机是天水风动工具研究所和抚顺红透山铜矿联合设计的新产品。由天水风动工具研究所于1970年试制样机四台,并与抚顺红透山铜矿一起,于同年11月1971年3月在抚顺红透山铜矿进行了三个多月的工业试验。该机与FJZ25型凿岩柱架配套,主要用于矿山采矿;配在凿岩台车上,可用于巷道、隧道掘进钻营炮孔。同时又是铁路、水利基本建设,国防建设,石方开采效率较高的凿岩设备。尤其是对于金属矿山的地下开采,采用此机能够取得较好的经济效果。它与FJZ25型凿岩柱架配套,可钻凿水平、垂直向上的炮孔,孔径40～55毫米,孔深可达15米。
YG40-type rail rock drill is Tianshui Institute of wind tools and Fushun Hongtoushan copper joint design of new products. Tianshui Pneumatic Tool Research Institute prototyped four prototypes in 1970 and together with the Hongtoushan Copper Mine in Fushun, conducted an industrial test of more than three months at the Hongtoushan Copper Mine in Fushun in November 1971 in the same year. The machine and FJZ25-type rock drill column supporting, mainly used for mining; equipped with rock drilling trolley, can be used for roadway, tunnel boring drill camp hole. At the same time it is a railway, water conservancy construction, national defense construction, rock mining efficiency higher rock drilling equipment. Especially for the underground mining of metal mines, the use of this machine can achieve better economic results. It is matched with FJZ25 rock drilling column, which can drill horizontal and vertical blast holes with the hole diameter of 40-55 mm and the hole depth of up to 15 meters.
